Hermie Seeds

Is there any reason not to use seeds produced from a hermie plant?
I started two white widow plants from seed. I was hoping to get a male and a female to produce some seeds, but they are both female with nuts. Now I'm hoping to use the seeds for next years grow. Since the plants turned hermie due to environmental conditions, lighting problems in veg. phase. What are the chances of these seeds producing hermie plants, and being useless to me?

If you go by pure punnet square (straight breeding) you're looking at 25% female, 25% male, 50% herm.

which means approx 1 in every 4 seeds produced will be female.

But it's a bit more complicated than that. To get more accurate results I'd have to form a hypothetical punnet square that doesn't exist for that type of determination (though I guess I could possibly try creating one, but that's a little different given the need to express the hermaphroditic genes within the table as well as male and female.)

Best chance is to say 25% of those seeds are female, and that's optimistic side. Cautious side would be more like half that, 12.5%

Some people claim that seeds from Hermies will always be Hermies. I personally don't feel that is true, I believe that they carry the genetics to become Hermies. They doesn't mean that they will all turn Hermie on you. I ahve also read some intersting things about marijuana genetics, specifically about hermie plants. I don't know how true any of the statements are but it's maybe something to research.

Seeds are not pre-determined to be male or female. Environmental factors have a lot to do with whether the seeds will produce males or females.

If you get seeds from a hermaphrodite plant, yes most likely the seeds when grown will hemie on you due to it's hermaphrodite trait being passed on.

Feminized seeds are made from pollinating a female with hermaphrodite pollen so yes there is a chance that feminized seeds can hermie on you.

Selfing

Selfing is the ability of a plant to produce seeds without the aid of another plant and refers to hermaphrodite plants that are able to self-pollinate. Hermaphrodite plants have both male and female flowers.This usually means that the hermaphrodite plant is monoecious. Most plants are dioecious and have male and female flowers on separate plants.

Monoecious cannabis strains will always display both sexes regardless of the growing conditions. Under optimal growing conditions a monoecious cannabis strain will still produce both male and female flowers on the same plant. Under optimal growing conditions a dioecious cannabis strain will produce male and female flowers on separate plants.

Stressful growing conditions can cause some dioecious cannabis strains to produce both male and female flowers on the same plant. Manipulating an irregular photoperiod during the flowering stage is an easy way to encourage the dioecious hermaphrodite condition. Not all dioecious cannabis strains can become hermaphrodites. The dioecious cannabis strain must have a preexisting genetic disposition to become hermaphrodite under stressful conditions in order for male and female flowers to appear on the same plant.

If you find a dioecious cannabis strain that has the hermaphrodite condition you can separate this plant from the rest and allow selfing to occur. If the male pollen is viable on this plant then the hermaphrodite will produce seeds. Selfed plants that produce seeds will eventually generate offspring that:
1. Are all female
2. Are all hermaphrodite
3. Produce male, female and hermaphrodite plants because the environment also influences the final sexual expression of the selfed plant
4. Express limited variation from the original selfed plant

Breeders should note that it is nearly impossible for a hermaphrodite to create male plants although the environment can influence males to appear. Hermaphrodites usually create female-only and hermaphrodite seeds. The female-only seeds often carry the hermaphrodite trait. Selfing has become popular among those who wish to breed all-female or feminized seeds. Unfortunately feminized seeds do very little for the cannabis gene pool as the hermaphrodite condition prevents growers from generating a sinsemilla crop.

Well-informed breeders tend to shy away from producing feminized seeds. Feminized seeds should only be used for bud production and not for breeding. Generating seeds from feminized plants is only advised for personal use and not for distribution.
