Quantitative Trait Breeding
Quantitative trait breeding refers to the selection and combination of polygenic traits—characteristics controlled by multiple genes rather than single-gene Mendelian inheritance. In cannabis, examples include plant height, flower density, terpene profile complexity, and cannabinoid ratios, which show continuous variation across populations. Breeders working in this category use statistical analysis, phenotypic data collection, and multi-generational selection to incrementally shift trait distributions within a lineage. Unlike single-gene traits (e.g., leaf morphology or seed coat color), quantitative traits require larger population sizes and longer breeding cycles to achieve stable, reproducible results. This approach is foundational to modern cultivar development, enabling refinement of yield potential, cannabinoid balance, and environmental adaptability without relying on rare monoge

Quantitative trait breeding underpins most contemporary cannabis improvement programs. Breeders employ progeny testing, phenotypic selection across multiple seasons, and sometimes genomic marker-assisted selection to accelerate gains in complex traits.
