Is there masculinzed seeds like there is feminized?

AgentPothead

Just this guy, ya know?
I swear this year I've had the very worst luck with seeds and they have all been male every last damn one I planted. All my clones are ladies buts I swear the seeds from this last batch all males. Anybody ever had this? Is it the environment? Did I eff something up?

yes can happen to several reasons.



look back the parental generation
error can be found there,


it is not the current enviroment, seeds gender are determined on the motherplant, not when its germinating or growing..

I bought somas “fem” somango seeds in 08, all males. I was pissed.

No, you can't get seeds that are all male. You can get random groups of seeds that are all male though, just like you can spin red 10 times in a row at a casino. Rare, but statistically, it has to happen sooner or later.

IB: The natural state in which hemp appears was and is dioecious. Monoeciousness is artificial in hemp, it can only exist with the help of man, and without selection, the dioecious state will return in two or three generations. It is therefore very hard and demanding to keep 90 to 95 % monoeciousness during seed multiplications. Apart from that, however, monoecious hemp is appropriate only when the crop is grown for so-called double use, i.e. when both stem and seed are harvested. This is the case in France and in the former Soviet Union, where most crops are grown for double use. In a dioecious crop, the male plants will be strongly deteriorated when the crop is harvested at seed ripeness, so in this case one needs monoecious cultivars. In Hungary and its neighbouring countries, like formerly in Italy, this double use is unknown. Here fibre hemp is grown as a dense crop which is harvested at the time of male flowering ("green hemp"), while seed production takes place in crops grown at a low plant density and with completely different growing techniques. For this 'classic' use monoecious cultivars are of no use, so we never bred a monoecious cultivar.
Furthermore, monoeciousness has two large disadvantages. In the first place, all monoecious cultivars which I tested over the last 20 to 25 years yielded 10 to 20 % less than dioecious cultivars. This is caused by the possibility of self-pollination and the resulting inbreeding. With model experiments and with biometric determinations we have established that 20-25 % of self-pollination takes place in monoecious hemp, and this is the cause of the lower stem yield. In the second place, in monoecious hemp, the genetic progress for fibre content is slow, because the so-called Bredemann principle can not be used. The Bredemann principle consists of the rapid determination of fibre content in male plants before they flower, so that only the males with the highest fibre content are allowed to pollinate the female plants. In a breeding garden (nursery) of one hectare, I have 15,000 to 20,000 plants and I need only the very best 50 to 100 males for the pollination. (This can be compared to breeding of dairy cows, where a few hundred extremely good bulls inseminate all the cows of an entire country.) In monoecious hemp this approach can not be used, so the rate of genetic progress is only 50 % or less of that in dioecious hemp. In spite of these disadvantages, we use a monoecious hemp cultivar in breeding, but only as a parent for unisexual hemp.

i've had other years when 3/4 of the Regular seeds i planted were female.

This year - I planted 30-40 seeds, and currently have 5 females and 5 TBD's.

got 5 males left, and already fed several males to the animals.

Anyway, WAY MORE MALES this year. and one enormous Hermie.


i still think there might be a way to tell the difference between male & female seeds. But it has to be a non-destructive test.

there is a theory on how to tell


altough i don t think it is 100% correct. give it a try next time

Masculinzed seed isn't possible. If you reverse a male and pollinate itself the resulting progeny will be regular seeds. So both male and female!

Check this thread out for more info on how to reverse males and what to expect in the progeny.

Whipedmeat, I too have seen that picture before. In that book does it talk something about pure female, mix seeds and males?

Cause like Jorge talks about in his book, I "believe" that you can alter some seeds to a certain degree with how they are treated in the seedling stage. Red light, water def, heat (?) can make them male. Blue light encourage females. Check his "bible"

yes, i read this too


it is an emergency system of some plants, i do not think these methods are able to change gender of the seeds but

are helpful to prevent hermaphroditism.


i think more important to have balanced parental lines these male overweighted batches are made with limited male stocks and it gives plants depression with the unbalanced ratio of males/females.


and than comes the bad enviroment with hot temps/ low humidity/ long light days


plants are born into the middle of summer, they can be confused and make as much males as possible

:dunno:hmm, I dont know could be. I often make my own seeds then I often use them in abondance when its practical. Not sure if its "luck" but sometimes I have a very good start and end with a lot of females and when I start mediocre because life happens. BAM, many males. It has happened a coulpe of times after I read it. Then again, maybe I find what I look after. :dunno:
