Sterility Male Female Imbalance
Sterility and male-female imbalance represent critical breeding challenges in cannabis genetics. These conditions occur when plants fail to produce viable pollen or pistils, or when populations skew heavily toward one sex during flowering. Environmental stress, genetic predisposition, and pollination failures can all contribute to these outcomes. Breeders encounter these traits when working with certain landrace lines or hybrid combinations that carry latent sterility alleles. Understanding the genetic basis helps identify which parent plants are likely to produce fertile offspring and which crosses may result in unexpected sex ratios or seed failure.

Breeders select against sterility traits when establishing stable seed lines, as even partial male or female sterility reduces breeding efficiency and seed yield. Conversely, some cultivators intentionally work with gynoecious (predominantly female) populations to minimize unwanted male plants in non-seed crops.
