Sex Determination Markers
Sex determination markers are genetic indicators used by breeders to identify plant sex prior to flowering. Cannabis exhibits environmental and genetic sex determination, with XY chromosome systems commonly documented in breeding literature. Molecular markers targeting sex-linked loci enable early identification of male, female, or intersex plants during seedling stages. This trait family is fundamental to breeding programs seeking to stabilize dioecious lines, develop feminized seed stocks, or preserve heterozygous populations. Understanding sex determination genetics informs seed production, breeding efficiency, and genetic stability across generations.

Understanding sex determination genetics informs seed production, breeding efficiency, and genetic stability across generations.
Breeders employ sex determination markers to reduce cultivation costs by eliminating males early, accelerate breeding timelines, and develop reproducible feminized seed lines. Marker-assisted selection targeting sex-linked regions supports the creation of stable breeding populations and inbred lines with predictable sex ratios.
