I post when I have the time. One fellow here from Oz that used to BS me all the time is banned now, so things are better. Was a time here when my posts would just get a lot of flap.
Fems can be used for breeding if you want to breed hybrids with other males. However, the issue with fems is that to breed them correctly, you need to chemically induce herming in them, and not use natural herms. Natural herms, random herms and herms forced by stressing will have and will pass on genetic herm traits. Like your Thai. Non-natural and non-stress response herming plants will not have herm genes. Thus those are the ones you want to breed with. But that takes plant stress testing, skill, experience and the right chemicals to induce herms. They also have to be bred with another female plant, or you will get the S1 self bottlenecking of genetics. The flip side is that it is really easy to produce seeds from natural and stressed herms bred S1, and hence they tend to be common. Read: Beware. There are a lot of fly-by night seed companies out there. Personally I have only used regular seeds from a relatively few seed companies, in particular MNS, RSC/Kwik, DJ Short, and Blue Hemp (defunct now). Most all of my seeds (save for 2 strains that I bought from central Africa) I collected myself from lids, or I traded for. Some of those early California lid seeds have hermed on me though, especially local grown sinsemilla from the early 1980s. Those herms tend to be half or quarter upper cola male flowers, in mid-bloom cycle. As opposed to Thai and Vietnam Black which have late bloom cycle single male pistil 'mutant' blooms. Herming was not well known about in the 1970s or even the 1980s. Nor was a lot about breeding weed in general. Books were few and growing experience was limited. I learned how to grow sinsemilla from a Mexican from Jalisco in Carmel Valley in the later 1970s. It is easy if you know what to do. But back then few knew. Or they were not diligent.
I do not know of any "stable" Thai or Vietnam Blacks. Especially landraces from SE Asia like those available at RSC. They are genetically prone to herming. Likely that trait has been bred into them over decades or even centuries of local SE Asia growing customs. They also bloom really really late. Like into January or even February late in North America. And they tend (for me at least) to be prone to PM from blooming so late into the fall and early winter here. PM is a new world disease, and Cannabis is an old world plant. For me SE Asian males also bloom ~later~ than the females. The males are also harder to force blooms using light dep. And even using light dep, the VN Black still did not finish until December here (under lights starting in late September). I know that Thai and VN Black herming has escaped into other strains as well. Some old school top breeders have reported that to me. Pollen is a very fine dust in the air barely visible. A cat, dog, kids, or bugs can track and transport it around. For that reason I have 5 greenhouses here. The males are in one, the females in another, and the other three are used for breeding one type of male with females. This also keeps any neighbors' or hemp farm Cannabis pollen from fathering any of my plants. Hemp here in Oregon is predominately fems grown from clones (or "plugs" as they call them) or fem seeds though, so pollen drifting from hemp farms is not really an issue.
Je collecte, sèche et congèle également le pollen pour une future reproduction. De cette façon, je peux choisir parmi une plus grande variété de mâles et de souches, et élever les mâles de l'année dernière avec les femelles de cette année. Je peux également élever des plantes hybrides qui, autrement, ne fleuriraient pas en même temps. Cette année, j'élève un mâle mj que j'ai cultivé l'année dernière qui est une souche de chanvre cette année, et les deux ont un taux élevé de CBC. C'est CBC, pas CBD. Ils ont tendance à être confus. Le pollen généralement congelé reste viable pendant environ 2 ans pour moi. Pour quelque raison que ce soit. Je congèle aussi les graines et le haschisch. Congelés, les graines et le hasch peuvent durer indéfiniment. J'ai des graines de couvercle d'Oaxaca, au Mexique, que j'ai eues de la saison de croissance de 1975 et qui ont germé à un taux de 80% cette année.

iimpressionnant! je vais aussi congeler du polen!
Comment procèdes tu ?
