Breeding Cannabis Autoflowers or Ruderalis

Breeding Cannabis Autoflowers or Ruderalis Autoflower Advantage Breeders use Ruderalis genetics to create plants that grow fast (typically around 70 days) from start to finish without you having to change daylength Autoflowering Trait is Recessive Autoflowering is a simply trait to observe for growers/breeders Keep plants in 12/12 light cycle and if it stays vegetative it is an autoflower and not a photoperiod dependent trait Recessive does not mean bad or negative, it does mean the plant needs two copies (one from the material and one from the paternal line) in order for this trait to be expressed. Backcross Breeding Backcrossing is a crossing of a hybrid with one of its parents or an individual genetically similar to its parent, in order to achieve offspring with a genetic identity which is closer to that of the parent. Backcrossed hybrids are sometimes described with acronym "BC", for example, an F1 hybrid crossed with one of its parents (or a genetically similar individual) can be termed a BC1 hybrid, and a further cross of the BC1 hybrid to the same parent (or a genetically similar individual) produces a BC2 hybrid. This breeding process is more restricted to recessive traits Breeding Autoflower with True Breeding Photodependent It follows the shown pattern of inheritance All of the offspring will be heterozygotes which means… All will be Photodependent (since it is a dominate trait) *but all will be Carriers for the autoflower trait This is the F1 generation Breeding F1 x F1 It follows the shown pattern of inheritance Offspring of desired trait will need to be selected for 75% will be Photodependent (since it is a dominate trait) 25% will be Autoflowers This is the F2 generation Breeding F2 Generation and Beyond Continued breeding and selecting will increase the amount of autoflowers in the population. Keep in mind that you may also want to watch the other plant characteristics (morphology, chemical profiles,…) to ensure you do not produce an autoflower that does not offer any other benefits. Often this is done for 5-9 generations 2nd generation = 25% Autoflower 3rd generation = 50% Autoflower 4th generation = 75% Autoflower 5th generation = 87.5% Autoflower 6th generation = 93.75% Autoflower 7th generation = 96.875% Autoflower 8th generation = 98.375% Autoflower 9th generation = 99+% Autoflower Breeding Can Get Complicated Many traits are polygenic, meaning there are multiple genes involved in the observed phenotype. While the basic roles of dominate and recessive still play a role the combination of multiple genes will result in what is observed in the final plant. This is why is may take more than simply three generations of selection to stabilize the autoflowering trait, but the basics still hold true and should provide a good starting point.
