Selfing Technique

Selfing is a controlled breeding technique where a single plant pollinates itself, either naturally or through deliberate intervention. This method produces seeds that carry genetic material exclusively from one parent, creating a uniform genetic line. Selfing is most commonly applied to hermaphroditic or feminized cannabis plants, where breeders can isolate and stabilize specific traits across generations. The technique differs fundamentally from outcrossing (crossing two distinct plants) and allows breeders to rapidly fix recessive traits or create stabilized cultivars. Selfing typically requires multiple generations to achieve homozygosity and trait consistency, making it a slower but highly controlled pathway in breeding programs.

Breeders employ selfing to rapidly develop stable inbred lines, test the genetic purity of parent stock, and create feminized seed lines. The technique is particularly valuable for isolating rare phenotypes, fixing morphological traits, or reducing genetic variation in breeding populations.
