View Full Version : all females through breeding?

This sounds great but I don't know enough about it.
Anyone have some input?

'Kompolti Hybrid TC' (registered in 1983) is a three-way-cross hybrid in which two selections from Chinese origin, 'Kinai Kétlaki' (dioecious) and 'Kinai Egylaki' (monoecious), and 'Kompolti' are combined. The first step of the crossing ('Kinai dioecious' x 'Kinai monoecious'), where the monoecious parent acts as pollen spender, gives a unisexual, almost pure female F1 , called 'Kinai Uniszex'. This unisexual progeny can be considered as an analogue for male sterile breeding lines. It is subsequently used as female parent in the crossing ('Kinai Uniszex' x 'Kompolti') which produces the commercial three-way-cross hybrid 'Kompolti Hybrid TC', which has again a 50/50 sex ratio.

well, I read that if you leave a female plant long enough after flowering it will start to produce its own pollen sacs, if you collect that pollen and then use it to pollinate a seperate female the chances are much greater that the seeds will produce female plants.

you have to remember to do all of the steps that i've forgotton, I guess there's a good chance of getting a lot of strange looking specimens too.

sorry, can't remember where i saw it, possibly I dreamt it.

I've read about what sombro is talking about in an article by soma. He claimed to invented the tek, and called it rodalization. Its really simple; most female cannabis will produce pollen sacs if let to flower for 10-14 days past mature point, and since these pollen sacs are created by one female plant with no males involved, they would be unable to contain male genetics. This gives a high chance of all female seeds, but it depends on how resistant your strain is to hermie traits, for this to be useful.

from what i understand, if you are to take a female plant and stress it into turning hermie (produce pollen sacks) and then use the pollen on another female plant (not stressed or hermied and preferably at the start of the flowering stage) the seeds it will produce will have a much higher rate of turning out female.

apparently the key is to get the pollen from a female that has been stressed into turning hermie. if you take pollen from a female that has turned hermie due to genetics it will cary on this gene in the seeds. whereas a plant forced into hermieng doesn't carry the hermie gene.

but i have never personally experimented or seen this with my own eyes. just my understanding from what i have been told by fellow growers.

cheers swissmj

attached pic of hermie plant, notice both pistels and pollen sacks are present. the photo is from some wild hemp growing in the area. cant smoke it and spreads pollen everywhere (sounds wrong but this hemp is actually a pest here and should all be destroyed) it sucks big time for the outdoor growers.

I'm such a dork, I go and talk about soma's rodalization after you (sombro) post a link to the whole article here on this site!

no worries, its all good.

took me about three hours to realize that it was here that i'd seen it!

Reckon I'll give this a try. There's gonna be some strange looking stuff growing this summer in the garden.

i have a few questions about what you are saying but I will got to the other thread to ask them. In the meantime, I was wondering if someone has any experience with a description like this one>>>cause to me it looks like "Kinai Uniszex" is an all female strain.

...gives a unisexual, almost pure female F1 , called 'Kinai Uniszex'. This unisexual progeny can be considered as an analogue for male sterile breeding lines.

sorry man, because it was in bold type I didn't read it, signature blindness it's called.

now that I've read it I'm sure that I cannot help in any way, I'm not even sure it's written in any known earth language.

googled a look but kept coming up with essays about detecting the genetic structure of different types of hemp for the improvement of hemp seed oil, it's out there.
