breeding for cold resistance

[xxDR.KICKASSxx]

the winters in my part of cali are cold as *&%* so I would like to breed a cold resistance strain. can it be done?if so how do I go about doing it? if this is the wrong forum sorry. thanks for any feedback. stay up stay safe

 

[xxDR.KICKASSxx]

no one has any feedback? this site has gone to shit

G`day DR K

Patience is a virtue they say ...

Get in contact with Esben from Hybrids from Hell .
He`s up in Denmark . I`m sure he`ll have some insight regards cold climates . Alternatively try posting in the Canadian or Finnish forums . They have adapted strains for their climates .

Thanks for sharin

lol you only waited 6mins.. yeah ive heard good things about hfh.. Ive known a few Scottish outdoor growers who used their strains.

Dr.

If you wanted to start from scratch, instead of buying an already awesome hfh variety, then you should research a nice stable genome already known for its cold resistance and cross it to something which you really like. It would take a lot of work and quite a bit of space.

If you found a good female(s) and a good male(s) then you would have to search through the initial cross to find the best individuals which show a good resistance to cold. If you started with good solid stable varieties to begin with then the f1 cross will be easier to select from as you won't have as many traits to sift through (depending on what you want). If you crossed multiple hybrids which weren't already locked down for traits then it might take a long time to find the cold resistant gene. If the parents are stable then maybe half the plants would be cold resistant (if the other parent doesnt hold that valued trait already). From these only some (if any) would be potent/have good smell and taste enough to keep. You would have to select only from females as selecting for a cold resistance in males would be almost impossible. After choosing your female(s) and male(s) from the f1 cross you pollinate again for an f2 gene pool where things get tricky. The f2 gene pool will be extremely varied (more so if the initial parents are multiple hybrids or not stable) and there will be a lot of recombination of the parental genes. Out of say 200 individuals then there might be something very unique within that gene pool which is totally different from the parents used.. The f2 is a gold mine and the key to locking down traits you desire (also the f3 gene pool but less so).. after selecting from the f2's then you cross again. The f3 gene pool will show more individuals with your desired cold resistant trait. You carry on as far as you want until maybe all plants show this trait. There can be many pitfalls along the way though and if the p1 parents are crap to begin with all could be a lot of work for nothing. Each generation would also have to be grown outside so you could select for cold resistance trait.

You might find the cold resistant gene pops up a lot which will make selecting more easy (this might happen if both initial parents are already cold resistant)

Or if you didn't want to start a stable seed line you could just select from the f1 cross and keep a desirable cold resistant mother from there and just take cuts every season from her.

Personally I would start with a Nepalese or Himalayan varietal as these are very cold resistant.

Or you could just buy Bangi Haze from Ace seeds and not have to put in all this work. The Bangi is renown for its cold resistance. If your set on producing your own variety then Bangi Haze would also be a good parent to choose since it is very stable.

You might get a better answer than this from someone more knowledgeable then me if this is moved to the breeding section..

Good luck

check hybrids from hell for possible breeding stock, lots of hearty northen outdoor strains that can handle 55 degree winters so cali should be a breeze

 

[tebos]

There is a Nepalese Highland Straing from Cannabiogen, which I would choose as a starting point!

Btw, is a fast indoor finisher also a fast outdoor finisher? Are indoor and outdoor traits the same or different from each other?

hi Dr,



hybrids from hell is great option with u can try and make you own seeds from some next lingeage what u selecet and work u cross for your area.
But u need 3 or 4 sesions to optimize u own cross in coner

good luck for you project

You could knock boots with your wife in the snow all night long, or you can turn on the heater and do it indoors. Just my two cents but you'll probably get better results indoors with a heater.

first off it should have said has this site and it was more like a day but any ways,thanks for the info

apologies it was a day and 6mins.

Pakistan kush plants hold their own. Nice big fat leaves for holding in heat. Mold resistance and good end product. Curious about Erdpert myself. Hard to find those beans. Any plant that is stocky, with close nodes, lot's of leaf surrounding mold resistant buds.

Tom's X18, then PCK and Pakistan Valley are all in my cache for cold weather crosses. We get frost here and I've seen X18 hold it's own mold free into mid november.

Even a plant like deep chunk could be crossed to survive a cold wet autumn. Get enough of the paki traits into the genotypes and the pheno's will express well outside. I would think nepal plants would do well, maybe some chinese or northern indian genetics. It's just easier to get paki genes due to the kush interest.

Bangi haze would work if the right genotype. Due to the chitral and nepal gene's. I'd be afraid of long flowering genotypes so be prepared for selection. Those african genes could make outdoors difficult. Anything with sativa traits stretches a lot around here, if not full sun all day. This reduces the heat the plant holds and they can't go past mid october. I like amber trichs and get lazy leaving plants outside.

I have a few power house x eroc/dp xdc so I am going to use that to start with.i got it from esbe a few years back

 

[burmese]

try nepalese//real seed company//,, i have grown kumaoni in wood box on balcony -10C only heat was from 23w cfl.......there were also original royal purple kush //purple haze x chitral backcrossed to chitral/ and it was affected in slightly leaf deformation. Small seedlings of matanuska survived but stop growing- but i have never seen so much trichoimes males from them //half pipe creeper KO stone//.
water low only with spraying water when the temp. is not below freezing.

mazar i sharif is the hardiest plant i know of.

for hardiness go nature selected "survival of the fittest" highland landrace where it gets cold. many of the northern strains come in way too early for me; low yields from small plants. mis came in late, huge plants. lots of highland landraces. go to the landrace seed sites.

if you want to breed then breed with various hardy landraces.

i am very happy i went to landraces for outdoor grows.

 

[Easy7]

I can't seem to find a pure mazar. It's an afghan so mold could become an issue. That is one factor that allows a partial daylight outdoor spot some good. If it doesn't get full sun all day, the buds don't get as dense and ventilate better. Never tried a pure afghan outdoors around here. Some autumns are very wet, in fact most of them right before harvest. Never had a problem with a paki strain.

 

[tebos]

Here (Edit: Mazar i Sharif from Ace Seeds) you go!

 

[The Hatter]

Nep Jam and Bangi Haze are both resistant to cold and wet conditions.

 

[Thule]

Yep, it's all about selecting the right genetics.. and exposing them to cold temperatures during breeding. There are good proposals in this thread, landrace based genetics, nordic outdoors strains.. lots to choose from.

 

[xxDR.KICKASSxx]

thanks for the feedback every one. I have ace seeds bangi haze
