howbto properly stabalozr cannabis seeds

Inbreeding depression will occur more slowly if there is an abundance of genetic material from which to form new offspring. Therefore, with smaller population sizes, inbreeding depression can occur rapidly. This is especially common in countries with a strong cannabis-using culture that have not decriminalised the means of production, such as the Netherlands where small libraries are maintained due to risk of discovery.

Well said! Kudos

Stable vs. true-breeding

It should be noted that any out breeding or back cross to the original and desired phenotype will result in an increase in genetic diversity requiring additional breeder selection and removal of undesirable traits.

you are too…..if you think your not, think again.

Thanks for sharing this knowledge. Just getting a grasp on breeding. Lots to consider, track and log and “TIME”
Cant help but hear @MotherNatures points about Sun Rain wind Organic outdoor altruism but science doesn’t stop.

Breeding cannabis and continuing a lineage in seed is not the exclusive preserve of the experts. Home growers that have acquired high-level cultivation skills and mastered the essential techniques can easily transition from grower to breeder. Creating F1 seeds and hybrids is very doable. Most of the cannabis strains that have become legends were created by home growers. On occasion even by accident.

Similarly, filial breeding can be complicated. Honestly, it’s far too demanding for the first time home breeder. By crossing a pair of F1s (first generation) the resulting progeny is the F2 (second generation). Unfortunately, these seeds will be far less stable and far more difficult to work with than the previous F1 generation.

WHY DABBLE WITH CANNABIS BREEDING AND GENETICS?

This is an old school ganja farmer’s method mostly applied outdoors. Although, breeding from the same batch has potential indoors provided the original organic seeds are genuine. If so, not only will the resulting progeny be more or less stable but you will have saved cash on seeds for the next crop.

Careful selective breeding in large numbers is required to succeed with this approach. Often it takes multiple generations of breeding perhaps until F5 (fifth generation) or even F6 (sixth generation) before the line can be stabilised.

Taking cuttings from cannabis plants is a great way to preserve a strain. Sometimes prized varieties are available in clone-only form, and the grower has little option other than continuing to take cuttings in order to preserve the genetics.

Once the plants are in the chamber, you have the option to keep them in the vegetative stage for a couple of weeks to boost their size. Alternatively, you can go right ahead and force them into flowering using a lighting schedule of 12 hours of light/12 hours of darkness each day. A few weeks into flowering, the male will grow pollen sacs which release the pollen. It lands on the females, and the pollination process is complete.

Genetically speaking, it makes more sense to only have a single male plant for breeding because one is enough to pollinate 20 or so female plants. This is called ‘intentional’ breeding. Spare a thought for the unfortunate growers who accidentally pollinated an entire crop of females with a male when all they wanted was some resinous weed.

Achieving Consistency When Breeding Marijuana Plants

Once you have mature seeds, you harvest and dry them. You can now finally grow the seeds on their own.

Now that marijuana is legal medicinally or recreationally in 33 states, breeders have more freedom to experiment. They can now focus on breeding to strengthen and purify strains, combining the desirable characteristics of strains, and enhancing traits such as potency and yield.

Once you have identified the strains you want to use for breeding, and have the requisite male and female plants , the next step is to place several females and a male into a special breeding chamber to ensure the pollen is contained. This may sound complicated, but you can create a DIY chamber by finding a suitable space and keeping it enclosed with the aid of plastic sheeting.
