Ploidy Level
Ploidy level refers to the number of complete sets of chromosomes present in a cannabis plant's cells. Standard cannabis plants are diploid (2n), containing two chromosome sets—one from each parent. Polyploid varieties, such as triploids (3n) or tetraploids (4n), result from chromosome doubling or hybridization between plants with different ploidy levels. Breeders document ploidy levels because they directly influence plant vigor, fertility, cannabinoid expression, and growth characteristics. Understanding ploidy is fundamental to predictable breeding outcomes and identifying hybrid stability in seed lines.

Breeders intentionally manipulate ploidy through colchicine treatment or selective crossing to develop plants with altered morphology, vigor, or sterility traits. Triploid and polyploid lines are often used in advanced breeding programs to create F1 hybrids with heterosis (hybrid vigor) and controlled reproductive capacity.
