Sterility
Sterility in cannabis refers to plants that produce little to no viable pollen or seeds despite appearing phenotypically normal. This condition can arise from chromosomal imbalances, genetic incompatibilities between parent lines, or environmental stress during critical developmental stages. Sterile plants are occasionally documented in breeding records, particularly in crosses between genetically distant or polyploid lines. Unlike male sterility, which is sometimes intentionally bred for seedless production, spontaneous sterility is generally considered an undesirable trait in seed programs. Understanding sterility patterns helps breeders identify incompatible crosses and maintain genetic viability in their work.

Breeders track sterility reports to avoid problematic pairings and to understand genetic compatibility barriers between different cultivar groups. In some cases, breeders intentionally work toward male sterility for seedless flower production, but unintended sterility signals potential issues with line stability or hybrid vigor.
