Post The hemp seed hub: A thread for those who seek seeds and infos on hemp

I've seen that there are a few people (including myself) looking for hemp seeds. Because there is nothing on the bay or in the boutique and the only available variety in small quantities I found so far is Suomi from the VSB, I decided to start a special hemp seed thread.

I think it'll be nice to have a hub for folks seeking not only hemp seeds but also informations on hemp cultivars, feral or wild varieties, and notably a place where you can communicate that you actually have access to this and that strain and like to share/trade.

I intend to keep this first post updated and will include latter contributions from other users about hemp seeds and varieties.
So please, feel free to contribute!

---------------------------------------------------------------------------------------------------------------------------

For those who like hemp for whatever reason but don't know which one to pick, I start with some infos on mainly but not exclusively European and Canadian hemp varieties.
The variety name is in bold, the admission country/-ies for registered varieties is in italic, and general informations are in regular letters.

Dioecious hemp varieties:
- Antal: Czech Republic and Hungary, rather tall, late maturing fibre and CBD variety
- Armanca: Romania
- Asso: Italy, dioecious according to DutchHempCBD
- Bergnaturhanf Ladir: Swiss landrace from Ladir, Graubunden (east Swiss Alps), listed in the 'conservation of plant genetic resources' (Swiss National Database) as possibly to conserve variety. Robust, unproblematic plant of 2 metres, THC content 2.4%
- Bernabeo: new Italian fibre hemp variety currently only used as breeding line, some plants are CBG-rich and devoid of THC and CBD (likely due a homozygous B0 allele)
- Bredemann: The 'Bredemann' varieties (e.g. Bredemann 18, Bredemann P, Bredemann Eletta) are famous German varieties selected from Central-Russian landraces by Bredemann. Bredemann became famous for his method using fibre determination in young males allowing for early selection of male breeding stocks.
- BundyGem: Australia, short and relatively early variety descendant from Canadian hemp and developed in the subtropics, rich in anthocyanins
- CanMa: Canada, se
ed hemp cross of a 'Finola' selection and an early 'ESTA-1', smaller very uniform size and medium maturing
- Cannakomp: Hungary
- Carmagnola: Italy, Northern Italian landrace from the southern ecotype (optimal temperature in vegetative phase ~23°C), CBD rich (though originally of mixed chemotype), tall, late flowering onset, parent line of several other varieties. 'Carma' is a CBG prevalent selection of 'Carmagnola' containing a unique set of CBG derivatives.
- Carmen: Canada, small sized
- CFX-1, CFX-2 and CRS-1: Canada, rather short seed hemp varieties with medium to large sized seeds and early to medium maturing (105-110 days), cold tolerant
- Chamaeleon: Netherlands, medium sized with early flowering onset, yellow cotyledons and yellow stems
- Crag: Canada
- CS (Carmagnola Selezionata): Selection of 'Carmagnola'
- Dioica 88: France, tall variety with late flowering onset (the latest blooming and the only dioecious French variety)
- Eletta Campana: Italian cross of 'Carmagnola' x German cultivar ('Fibridia' or 'Bredemann'), tall and late flowering onset, THC 0.6% & CBD 0.8%
- ESTA-1: Canada, Ottawa valley seed hemp, flower onset at ~50 days, small (~150 -180 cm)
- Fibranova: Italy, depending on source either 'Bredemann Eletta' x 'Carmagnola' or a hybride of Turkish and German varieties with 'Carmagnola' (optimal temperature in vegetative phase ~23°C), CBD rich, tall and late flowering onset, purple stems
- Fibridia: Important hybrid of northern and southern ancestors
- Fibrimor: Italian cultivar
- Finola (FIN-314): Finland, a stabile cross originally made by Sam_Skunkman and Dr. J.C. Callaway by open pollination of two Russian landraces from Kirov @ 58°N (Northern type accessions k-313 and k-315 from the Vavilov Institute of Plant Industry VIR) in 1995 (Callaway & Laakkonen). Nowadays, mainly grown in Finland and Canada. It starts flowering when 25 to 30 days old, is the smallest (~150 -180 cm) and earliest (~100 days) industrial hemp variety, has fine fibres and gives a large harvest of small seeds. THC/CBD content in late flowering may be above legal limits.
- Fleischmann hemp (F-hemp): A legendary Italian variety from the '50 based on 'Carmagnola' and parent line to many modern cultivars in Italy, Hungary and former Yugoslavia
- Havelländer (Havelländischer Hanf): Famous German heirloom-variety based on Russian hemp, short and early flowering/maturing with high seed and biomass yield but low fibre content.
- Helvetica (several varieties): Old Swiss variety, medium THC and CBD content (occasionally above 1%, hence no EU/CH approval), rel. late flowering onset
- Kompolti: Hungary & Netherlands, selected in Hungary from 'Fleischmann Hemp', THC 0.1% & CBD 1.5%, some specimens with medium THC-content (temporarily lost EU approval), very tall fibre variety with late flowering onset, parent line of several other varieties
- Kompolti sargaszárú: Hungary, a spontaneous chlorophyll-mutation with deep yellow stems and lime green leaves found in a cross between a Finnish and an Italian variety in 1939 and inbred to 'Kompolti' (BC3F3) by Iván Bócsa ('sarga szárú' translates as 'yellow-stemmed')
- Kuhnow (Kuhnowscher Hanf): Old East German heirloom variety based on Italian hemp. Late maturing fibre type.
- Lovrin 110: Romania, THC 0.7% & CBD 1.3%, medium to very tall, intermediate flowering onset, selection of different types from the Bulgarian Silistra landrace 'Silistrenski' (a southern ecotype), suitable for essential oil production
- Novosadska konomplja: Serbia, Yugoslavian variety, an improved selection of 'Fleischmann Hemp'
- Petera: Canada, large seeds, tall (3 - 3.5 meter), late maturing
- Ramo: German variety, intermediate flowering onset, low cannabinoid content
- Rastslaviska (Rastislavicke): Czechoslovakian heirloom variety or landrace of the southern ecotype, tall growth and late flowering onset, THC 0.2% & CBD 1.8%
- Red Petiole: Italy, has red petioles and a very low THC content due to irradiation with radioactive cobalt
- Schurig (Schurigsche Hanf): Famous German heirloom-variety cultivated around Markee. Either a selection from Central-Russian variety or a hybrid of Northern and Southern ecotypes with a small portion of subdioecious individuals. Schurig's hemp gave rise to the first true monoecious hemp variety 'Fibrimon' (see section 'monoecious varieties').
- Silvana (SV.200): Romania
- Suomi: A hemp variety marketed by the Vancouver Seed Bank, likely to be 'Finola'
- Superfibra: Italian cultivar, tall and late flowering onset
- Tiborszállási: Hungary & Italy, Hungarian landrace of the southern ecotype (optimal temperature in vegetative phase ~19°C), medium tall with mid-late flowering onset, parent line of several other varieties
- X59 (hemp nut): Canada, early, shorter Canadian grain variety
- Yunma 1 to 6: China, according to the manufacturer Yunnan Industrial Hemp Inc. 'Yunma 1' is the first legal Chinese fibre and seed hemp variety. These Southern Chinese plants are adapted to 23-30°N, grow tall and fibre maturation is late, seed maturation very late (110 and 190 days, respectively), THC concentration is according to EU standards. It is said to be a mix between 50% dioecious and 50% polyoecious plants. N°2 to N°4 are true dioecious; for more infos see link above.

Only ornamental cultivars:
- Panorama (the world's only ornamental hemp cultivar): A Lebanese strain selectively bread by Dr. Iván Bócsa in the '80. Here some nice infos with a picture of him and two 'Panorama' on book page 311 (PDF page 28) on Hort.Purdue.edu or an interview with him on Hempfood.com. 'Panorama' is of the mixed chemotype with medium low total cannabinoid content.
- Ermes: Ermes is actually a monoecious fibre hemp variety which may obtain EU approval in the near future. Its ornamental quality comes from the webbed leaf trait known in Italy as 'pinnatifidofilla'. 'Ermes' is an inbred line obtained from one single 'Fibranova' male plant (obtained by irradiation with radioactive cobalt) and CAN-19 aka SiMonA (a subdioecious variety from southern Italy). FYI The webbed leaf and single leaf traits are known from Italian varieties since the early 19th century but the trait in 'Ermes' is recessive and hence serves as visual marker for purity of the variety.
- Fibror 79: Relatively new yellow stemmed variety. Haven't found anything else on it so I simply stick it to the ornamentals, at least for now.

Unisex hybrids and dioecious x monoecious crosses (female predominant varieties):
As a side note: The number added to the French F* hemp varieties (e.g. Fédora, Félina etc.) corresponds to the time to maturity, all are female predominant with <1% male plants. The same holds true for Epsilon and Santhica but not for Russian varieties (e.g. USO).
- Alyssa: Canada, female predominant variety with 85-90% females, flower onset at ~60 days, small (~150 -180 cm).
- Carmaleonte: Italy, new 2016 fast retting, yellow stemmed variety, a cross between Carmono and Compolti sargaszárú
- Fédora 17, 19 and 74 (the numbers refer to flowering onset): France, 'Fédora 17' was the last variety to lose approval in Switzerland (1. June 2014), a medium sized variety with 50% females and 50% monoecious plants. 'Fédora 19' [('JUS-9' x 'Fibrimon 21') F1 x 'Fibrimon 21'] is taller, has a relatively early flowering onset, up to 1.2% CBD, but a poor essential oil quality. 'Fédora 74' has an intermediate flowering onset.
- Fédrina 74: Female predominant French variety, tall with late flowering onset, ~1.5% CBD, ('Fibridia' x 'Fibrimon 24') F1 x 'Fibrimon 24'
- Félina 32, 34: France, variety with 50% females and 50% monoecious plants, originally medium THC and CBD content but now only up to 1.6% CBD, medium sized with intermediate flowering onset. 'Félina 34' = ('Kompolti' x 'Fibrimon 24') x 'Fibrimon 24' has a low optimal temperature in vegetative phase ~13°C and shows a short flower induction (or photoperiode induced) phase making it 'autoflowering' in Southern Europe, suitable for seed and essential oil production.
- Fibriko: Hungarian variety, similar to 'Kompolti hybrid TC' but with the yellow stemmed variety 'Kompoltki Sargaszaru' as parent, phenotypically dioecious and not yellow stemmed (F2 should result in 25% offspring with yellow stems)
- Futura 75 and 77: France, female predominant French varieties, 'Futura 75' is medium tall, has a relatively high optimal temperature in vegetative phase of ~20°C and an intermediate flowering onset. 'Futura 77' [('Fibridia' x 'Fibrimon 24') F1 x 'Fibrimon 24'] grows tall with a late flowering onset and up to 1.6% CBD
- Hohenthürmer Gleichzeitig Reifender: German variety, the first female predominant variety obtained by selective breeding with a few spontaneously occurring monoecious plants in a landrace from the upper Waag valley, Slovakia. Likely hybridised with 'Schurig' and 'Kuhnow' hemp varieties.
- Kompolti hybrid TC: Hungary, F1 of the Chinese 'Kinai unisex' (dioecious 'Kinai Ketlaki' x monoecious 'Kinai Egylaki') x 'Kompolti', phenotypically dioecious, late flowering onset, high quality essential oil
- Lipko: Hungary, variety with 50% females and 50% monoecious plants, rel. late flowering onset
- Secuieni 1 and Secuieni Jubileu: Romania, 'Fibrimon' hybrides, 'Sucuieni Jubileu' is a 'Secuieni 1' selection. Female predominant with ~5% male plants, suitable for essential oil production. Unlike the latter, the former is not in the EU catalogue due to slightly elevated THC content (~0.5%). Early-medium flowering onset, hight, fibre and seed yields are medium, bast content is high.
- UNIKO-B: Hungary, tall fibre variety with rel. late flowering onset, the F1 hybride ('Kompolti' x 'Fibrimon 21') consitst of nearly only females (unisex, see below) and is used to produce exceptionally high yields of sowing seeds for the commercialised F2 fibre hemp generation (~30% male plants). BTW Unisexual and to a lesser extent monoecious cultivars aren't stable and result in an increasing mix of different phenotypical 'sexes' after a few generations.
- Unisex cultivars are produced by pollenise a dioecious mother plant with the pollen of a monoecious father. The F1 generation consists of over 90% females, 3-5% monoecious plants with mainly female flowers and only 2-3% true males. Several of the French varieties are the F2, back-crosses of such F1's to the monoecious father line resulting in approximately 50% true females and 50% monoecious plants. A nice lecture on this subject, Kompolti varieties, and the invention of UNIKO-B can be found again on Hempfood.com: Interview with Dr. Iván Bócsa and also the Journal of the International Hemp Association Vol. 2 No. 2, 1995.

Dioecious varieties from Russia and Ukraine include the dioecious southern ecotypes (e.g. Ukraine) 'Kuban' (low cannabinoid content) and 'Zenica' (aka 'Shenitsa') and the Central Russian ecotype 'Ermakovskaya Mestnaya' (likely a Siberian landrace), all other current cultivars are monoecious hybrids of central and southern hemp varieties and often begin with 'USO-', 'YUSO-' or 'JSO-' followed by a number. Notably, the Sovjet Union grew several landraces in different climate zones between 32 and 60 °N, mostly in South and Central Ukraine and 'ruderalis' type hemp around Saint Petersburg/Leningrad. With the introduction of monoecious varieties in the '60s of last century, new hybrid breeding with 'Bernburgskaya Odnodomnaya' ('Bernburger Einhäusige', that's where the O in 'USO-/YUSO-/JSO-' comes from), showing a 2-3 times higher fibre content, took over. Due to strict laws since the '80s, only a few monoecious varieties with very low THC content are cultivated in Ukraine but some old dioecious varieties are still maintained for research and breeding projects. These 'modern' varieties are extremely low in THC or even completely cannabinoid free and include the monoecious varieties 'Dneprovskaya Odnodomnaya 6 and 14', 'USO-14', 'USO-16', 'USO-31', 'Zolotonoshskaya 11, 13, and 15', 'Glukhovskaja 33 and 46', 'Dneprovskaya monoecious 14', as well as 'USO-42' and 'USO-45'. See also Canadian hemp section.

This brings me to monoecious varieties. Although having certain advantages in terms of fibre quality, harvesting, and breeding, I still don't like them. Noteworthy, new French and German cultivars are usually monoecious and extremely low in THC with a good proportion of THC-free individuals (e.g. 'Santhica' and 'Epsilon' varieties); they might be crosses of USO-31 (quod est demonstrandum)...
Nonetheless, here's a small compilation of monoecious, possibly monoecious or eventually female predominant varieties (* = I don't know which of the three) mostly with EU and/or Canadian approval (if approved, country code in italic). Problem is, many female predominant varieties are listed as monoecious even though they are for example F1 hybrids of dioecious females x monoecious 'males'; a drug type cannabis grower would say that they are 'feminised' using a 'hermie' as pollen donor .
First of all, Reinhold von Sengbusch was the one who, in the 1940s, bred the first true monoecious variety 'Fibrimon' by successifely culling males, a process called 'femeln'. He started his work for the Max Planck Institute in Markee near Berlin but the latter breeding was done in the French Pyrenees by M. Nicot this hybrid of northern and southern ecotypes (others speak of a Central Russian variety) is commonly regarded as a French variety. It is based on 'Schurig' hemp and seems to be the parent to all monoecious varieties including the famous 'Bernburger Einhäusige', an heirloom variety bred around the same time at the Akademie der Landwirtschaftwissenschaften in Bernburg, Germany. Just a few years earlier, Walther Hoffmann bred the 'Hohenthürmer Gleichzeitig Reifender', the first female predominant variety having roughly 90% females and the rest monoecious plants and males. It never became as popular as the 'Bernburger Einhäusige' and disappeared together with most other heirloom varieties when Fibrimon became and remained popular.

Anka (CA, tall, medium/late flowering), Bialobrzeskie (AT, CZ, PL, high quality essential oil) and Beniko (AT, NL, PL, poor essential oil quality) (first and second Polish monoecious variety, respectively, both hybrids of 'Fibrimon' and southern ecotypes, tall under optimal conditions and with intermediate flowering onset), Canda* (CA), Carmono (IT), Codimono (IT), Dacia Secuieni (RO), Delores* (CA), Delta-Ilosa* (ES, seed variety), Delta-405* (ES, seed variety), Deni* (CA), Denise (RO), Diana (RO), Dneprovskaya Odnodomnaya 6 and 14 (UA), Epsilon 68 (FR, small-medium sized, mid-/late flowering), Ermes (IT), Ermo* (IT, total cannabinoid content <0.05%), Fasamo (DE, medium tall, early flowering hybrid of central and northern ecotypes, thin stalks), Férimon (DE, FR, medium and intermediate flowering onset, rich in oleic acid), Fibrimon and its selections Fibrimon 21, 24 and 56 (parent lines of most French female predominant F1 hybrids), Fibrol* (HU), Irene (RO), Ivory* (NL, fast retting), Joey* (CA), Jutta (CA, tall, late flowering), KC Bonusz* (HU), KC Dóra* (HU), KC Virtus* (HU), KC Zuzana* (HU), Marcello* (NL), Markant* (NL, fast retting), Monoica* (CZ, HU), Ratza* (RO), Santhica 23 (contains mainly CBG), 27, and 70 (FR), Silesia (CA, third Polish monoecious variety, tall with intermediate flowering onset), Szarvasi* (HU), Tisza* (HU), Tygra (PL), UC-RGM* (CA), Wielkopolskie (PL), Wojko (PL), YUSO-14, 16 and 31 (USO-14, -16, and -31, very early seed hemp varieties for colder climates (USO-31: NL)), Yvonne* (CA, tall, late flowering), Zenit (RO), Zolotonoshskaya 11, 13, and 15 (USO-11 a 'Fibrimon' hybride, -13, and -15, UA, tall varieties)
And here the remaining EU registered varieties where I haven't found any information on Google: Carma (IT, a prevalent CBG variety containing mainly the cannabigerol-derivatives carmagerol and sesqui-CBG as well as cannabivomone), Rajan (PL), Succesiv (RO, new 2017 variety), Villanova (IT, new 2017 variety)

Several of the (partially) monoecious varieties are crosses with strains selected in Germany (e.g. 'Schurigs', later called 'Havelländer', and 'Bernburger Einhäusige') though the original monoecious 'mutation' originated in Russia...

Legend:
- CBD rich means around 2-3% and medium would be around 1%. Notably, it's % of dried whole aerial parts, leaves and stems included!
- Early, intermediate and late flowering onset means flowering starts at approximatively 50-60, 70-80 and 90-100 days, respectively (if I didn't mix up something).
- The countries are the countries of origin (the original germ plasm in these varieties, as often, comes in part from somewhere else) and/or the countries of main cultivation or cultivar maintenance. Notably, these varieties are well adapted to the indicated countries climate! The main germplasms within the list above originate from France, Italy, Hungary, and Russia/Ukraine. Many are stable hybrids selected from crosses with strains developed around WWII for example in Germany.

THCV/CBDV rich varieties:

According to Staginnus et al. (publication HERE), the EU approved variety 'Szarvasi' is of Asian origin, dioecious, and contains 1-2% THC and also THCV... unfortunately, I could not get more informations regarding this variety.

---------------------------------------------------------------------------------------------------------------------------

Here some infos and resources about US feral hemp (the progeny of the legendary Kentucky hemp varieties):

Beginning 1900, the small, Christmas tree like US fibre hemp was primarily of European origin but was successively crossed with mainly Chinese varieties to obtain huge plants with minor branching. Therefore, the resulting Kentucky hemp varieties were blends from all over the world. From what I've found on the net, 'Kymington', 'Chington' and 'Tochimington' were the three best performing varieties. 'Chington' is a Chinese strain whereas the 'Tochimington' contains Japanese genes. The 'Kymington' seems to be a mix of different US lines... But, as stated by Lyster H. Dewey (link below), the favourable traits for fibre production diminished after ~10 generations (= 10 years) and the varieties needed to be crossed again with tropical strains. With the prohibition era and due to errors and bad luck, most (if not all) of these original varieties got extinct and are lost forever. What remains of them is feral hemp, known as ditch weed, growing wild at several places mainly in the Midwest. Obviously, today's US feral hemp is a wild mix of different selectively bred lines from the years ~1920 to ~1940 acclimatised for over 70 years to the local climate and containing to some degree or another genetic influences of modern varieties (industrial hemp or drug type cannabis).

Great reading is this article about the 'Fiber Wars' by David West (seems to be THE person for US fibre hemp history): Globalhemp.com
And an article about the origin of some famous US varieties: Hempology.org
The most important breeding, selecting and crossing experiments were performed at what's known as 'Arlington Farm'. The lovely thing about that is its location: It was where the pentagon now stands . Found that here (and also elsewhere): Washingtonpost.com

---------------------------------------------------------------------------------------------------------------------------

Some considerations on crossing fibre/seed hemp with 'drug type' cannabis (literature is the same as above):

- Many hemp varieties ('Carmagnola', Chilean, 'Felina 34', 'Fibranova', 'Futura 77', Kentucky, 'Kompolti', 'Tiborszállási') have a switch-point photoperiode (maximum day length for flower induction) of ~14 h. Notably, hemp reacts also to temperature causing for example 'Felina 34' to flower seemingly spontaneously in Southern Europe.

- Breeding for high THC content in fibre/seed hemp seems more promising when crossing a THC rich cannabis female with a hemp male than vice versa. Remember, hemp is defined as A) low in overall THC+CBD content (usually <<5%) and B) a ratio of THC:CBD much smaller than 1 (sometimes ~1). Old cultivars and landraces with 2-5% THC+CBD and a ratio of 1 already in certain plants of a given population have been banned by most countries! The THC:CBD ratio is genetically determined by co-dominant alleles BT and BD but cannabinoid amount seems cytosol or mitochondria bound and hence is inherited mainly by the female part. An F1 of hemp (female) x cannabis (male) usually results in a THC:CBD ratio of 1 and a cannabinoid content either as low as in the hemp or at best intermediate but with few deviations between siblings (CBD may be higher due to a heterosis effect: Genetics.org). The favourable cross the other way round may depending on the hemp variety result in a ratio of 1 or of THC only and a cannabinoid content with higher deviations between siblings attaining 'drug' level for some individuals. With this cross, the F2 (first sibling cross) will result in an even higher deviation with a realistic chance of finding a plant or two of the BT/BT type (theoretically 25% of the plants) with a high THC:CBD ratio and also high total amount (depending on 'luck'). A lower content could also be observed and may be due to loss of the heterosis effect (Uni Halle, Dissertations online). Obviously, one can increase the chance by crossing the F1 back to the cannabis parent and test the THC and CBD content not only of the crosses but also of the F1s (even with a simple method like TLC).

- Breeding for high CBD in fibre/seed hemp is similar to the above mentioned high THC strategy. Again, cannabinoid amount (THC and CBD) is inherited by the female plant whereas CBD and THC chemotypes are sex independent and the strategy remains principally the same.

- Noteworthy for those who want to cross Canadian hemp; the three main cultivars in Canada are 'Crag' (dioecious), 'USO-14' and 'USO-31' (both monoecious Russian cultivars) and make up 90-95 % of total Canadian hemp crop (though 'Finola' is gaining in importance). Only these three varieties are exempt from regular THC testing because of there extremely low THC content (generation after generation below 0.1 % for the whole population tested so far). Therefore, for those who like to cross-breed an unknown Canadian industrial hemp with drug type cannabis, chances are high that the offspring will be extremely low in THC even in the F2 and F3 generations (without back-crossing to the drug type) not to mention eventual troubles with hermaphroditism. At least in case of 'USO-31' the former is due to the homozygous 0 allele o/o preventing any cannabinoid synthesis and strongly suppressing it in heterozygous form (CSATC.org), although there are patent claims on 'isolating the B0 allele from USO-31'. Because 'USO-31' produces not even the precursor CBG strongly supports the '0 allele' hypothesis (D. Pacifico et al.).

- Crosses with Italian and Hungarian varieties seems favourable when opting for high THC and/or CBD in the crosses because most contain either 'Carmagnola' or 'Kompolti'. These two varieties have already elevated levels of CBD (around 2-3% with some individuals even higher). Although, these two varieties are amongst the best fibre strains; they are tall, barely branched, flower late and finish late and prefer the climate of southern Europe.

- Crosses with seed hemp and northern varieties have the advantage that these cultivars are often smaller, flower and finish earlier and notably have a better ratio of flowers to leaves than pure fibre strains. On the contrary, they are often adapted to northern European or Canadian climate and may not do as well indoors (remains to be proven LoL). They also have medium sized to large seeds which doesn't disturb in sinsemilla weed .

- Crosses with the French 'Santhica' and 'Epsilon' varieties may be tricky if one tries to maintain or introduce a certain level of THC or CBD into the cross because 'Santhicas' and some 'Epsilon 68' individuals contain nearly none of both: Heard rumours that they have the B0 allele (codes for a non-functional CBD synthase) which shunts of any THC or CBD production in homozygous individuals. By the way, the B0 allele is recessive (Springer.com). It seems more likely that these varieties have the same o/o allele as 'USO-31' mentioned in the Canadian hemp section because no elevated CBG levels are found in the case of 'Epsilon 68'. The breeding line 'Barnabeo' on the other hand has individuals which likely carry the B0 allele and hence shows an elevated CBG content (D. Pacifico et al.).

- For those who want to breed hemp with cannabis for the auto-flowering trait, keep in mind that this trait (i.e. flowering depending on age and not photoperiod) is usually recessive. An F1 will not be auto-flowering and only 25% of an F2 (sibling cross) will show that behaviour and there is no obvious way to cheat chances. It looks like if there were no approved cultivars (besides wild C. cf. ruderalis) with that trait; all the agricultural varieties seem to be just early flowering (maybe flower induction due to size like in the 'super-auto' strains?). AFAIK, early flowering is either a multi-genetic trait and the precise inheritance unknown but can be improved successively by selective breeding (as has been done with 'Finola') or can even be dominant (strangely 100% of the F1 and F2 show early flowering: Uni Halle, Dissertations online). Obviously, one can increase the chance by crossing the F1 back to the hemp parent.

Maybe you want a high THC auto-flowering cross? Chances are at a mathematical 12.5% of getting an auto-flowering plant with a high THC:CBD ratio when crossing drug type cannabis x hemp siblings (i.e. F2) and are a good deal lower for high THC percentage (as this isn't determined by a single allele). Again, test the F1 parents and not only the F2 offspring for THC and CBD amount (what counts at the F1 level is high THC plus CBD and not only THC alone)! If you back-cross to one or the other parental line you risk to lose one or the other wanted trait. Therefore, a sibling cross or selfing seems more favourable to me.

Where to buy seeds legally?

- First of all, look at the European 'COMMON CATALOGUE OF VARIETIES OF AGRICULTURAL PLANT SPECIES' (HERE, change the EN in the URL to FR or DE if you want it in French or German; may also work with all other EU languages). At the end of the document, you'll find all European agricultural agencies responsible for agricultural hemp seed 'handling'. Although, you can't buy just a few seeds (usually bags of 25 kg for € ~250) and may require a permission.
- Browse through gene banks, for example the IPK Gatersleben, the national gene bank of Germany, has over 50 different hemp varieties from around the globe, some landraces, others standard monoecious cultivars and so on. Upon simple registration (SMTA required!) they provide small samples of mostly any crop for free (certainly to universities and institutes, but seemingly also to private persons). Genbank.at, the Austrian centre, has a small list of hemp accessions, whereas Agroscope, the Swiss centre, doesn't list any hemp cultivars but has a huge list of other agricultural plants. Should you happen to be in Saint Petersburg, contact
Sergey V. Grigoryev, curator responsible for hemp at the VIR. Better call (+79215573878) than mail (ser.grig@mail.ru) him . He is very friendly and will certainly give you some samples but unfortunately he can't ship them to you and more importantly, they had considerable budgetary cutbacks. Of the 500 listed hemp accessions only a too small part is still actively maintained ex situ and possible to share. Nonetheless, they hold the worlds largest hemp seed catalogue. All European Seed banks (not only for hemp) are re-grouped on THIS site, note that Ukraine corresponds to the VIR, Germany to the IPK, and that Hungary and Romania have huge collections too (though I'm not aware of their willingness to share seeds). The Netherlands have a national hemp and cannabis seed collection hosted at the Wageningen University; unlike most other seeds, Cannabis accessions aren't publicly listed but can be obtained on demand (should you qualify customer, they charge € 450.- per sample).
- For small quantities, have a look at your local or online garden centre. Swiss folks can find some varieties for example
@ Samen-Mauser.ch (2014: Fedora), @ Saemereien.ch (2014: Low-THC fibre hemp and Fedora), @ SwissHempShop.com (2014: Carmagnola, Finola, 'Speedy' and 'SwissMix'), or @ ProSpecieRara.ch for benefactors only (Bergnaturhanf Ladir). People from Austria have the possibility to purchase plants @ FloweryField (2014: Beniko, Delta-Llosa, Felina 32, Fibranova, Red Petiole, and Santhica 27).
- Visit a health-food shop. Many such stores in Finland have hemp seeds on offer. This is likely the least expensive version for smaller quantities of Finola. I ordered there and am very happy!
- If you have a Chinatown nearby, go there for a stroll. Many shops sell Chinese hemp seeds. These are very tall, tropical varieties which will not finish in time in Europe, Canada or Mid/Northern USA. Furthermore, these varieties are often not selected for low THC and/or CBD chemotype; be aware that such a plant could pose a legal issue not only by being a non-approved variety but also for eventually too high THC concentrations!!

My wish list: Finola, Kentucky hemp, Helvetica

As it was me to start this thread, here's my hemp seed wish list:
- 'Finola' aka FIN-314: Only a few seeds and not the 25 kg which may be purchased from www.finola.fi for € 250.- (EDIT: fond it, grow it, enjoy it )
- Feral Kentucky hemp: It should be purple or otherwise highly ornamental, great smell/taste with a high essential oil content, small and Christmas tree like growing, early flowering and maturing, strictly dioecious. Best would be if it didn't came from an area where industrial hemp is cultivated nearby to avoid crossings with that one.
- 'Helvetica', ' Bergnaturhanf Ladir' or other old 'pure' Swiss hemp cultivars: The ones I tested as tea back in the '90 had a great taste!

You found a variety called Suomi? That's the local name for Finland so I would think it to be finola since nothing else is grown here.

The Vancouver Seed Bank offers suomi... speculations really are that its just Finola. Simply that I've read more than once that the suomi plants are weakly cripples... We're talking about that elsewhere: answers #14 and #15 https://www.icmag.com/ic/showthread.php?t=271195

Do you mind if I ask whether you have access to some seeds (guess it's around harvesting time anyway up north)? And as you said, every commercial field in Finland is likely to be Finola...

Access, sure It's my breakfast. This years seeds won't be out before winter but organic shops probably have some stock left. I've sent links to people in the past so I could probably look one up.

Btw, I don't think finola is a ruderalis cross.. they just share a common origin.. a long time ago.

Well, well, well... I would have found it myself if I'd searched for 'hampunsiemen'... but I don't speak Finnish (not even Swedish)... Thanks a lot though!
Now I just have to figure out how to buy it on a page where I don't know where to click; to my eyes it's as bad as a Chinese site LoL.

As said, Finola is allegedly a ruderalis cross... the one thing sure is that it originates from the VIR seed stock in Hungary and was 'created' not thaaaat long ago.
Is there a reason why you think so? Doesn't it look/taste/smell like ruderalis or what else? Either it's its appearance (my opinion doesn't count, I've only seen pictures) or the auto-flowering trait which led people believing in the ruderalis story, I guess.

Actually Vavilov institute in Russia. It's a cross of two Russian landraces, atleast one of which originates in Siberia, where you wouldn't expect to find anything but autoflowering varieties, even in hemp. Yeah, it doesn't look smell nor taste like ruderalis.. but I never saw any Russian rudies, just European ones. The thing is, when fresh, finola seeds sprout in hours after soaking. Ruderalis takes 5 months. Finola is about as domestic as it gets but there's no doubt in my mind that it originates from the Russian ruderalis genepool.. thousands of years ago.

Thanks for the correction and explanation! No idea why I thought that the VIR's in Hungary if the VIR is located in St. Petersburg, and that's obviously in Russia... Really need the week-end!
What is the smell/taste of Finola like? Would it be good for tea and seasoning?

I find it ironic that I can order all the high THC seeds I want from Europe but cannot get hemp seeds with no THC. You would think some enterprising seed bank would buy hemp seed by the kilo and then resell it to an increasing number of Americans like me who want to fool around with it for various reasons, high CBD, fiber, food, whatever. I'd like a couple of kilos of seed. Growing hemp is now legal in my state.

Out of a couple of hundred Suomi seeds I tried I could only get about five to grow to maturity. One was the most anemic, tiny male plant you can imagine. I thought maybe the seeds were just very old but your explanation, OO, in the other thread makes sense.

I'm hoping for better results with the small stash of seed I collected.

It's been a while since I smelled any but I think the smell was very piny, fresh, grassy, some fruitiness in the background maybe. People described it as pine forrest. High pinene content for sure and very distinct.

Should be ok as a tea, it has that fresh taste, oil should be good too but it's not a delicious odour compared to most drug strains. Depends on what you like really, but it was never bred to taste good.
