Phenotypic Screening
Phenotypic screening is the methodical evaluation of observable plant characteristics—morphology, cannabinoid ratios, terpene profiles, flowering time, and yield potential—to identify desirable traits in cannabis breeding programs. Rather than relying on genotype alone, breeders use phenotypic screening to assess which plants express desired traits in actual cultivation conditions. This practice is foundational to selecting parent stock and stabilizing new cultivars. Environmental factors, nutrition, and growing methods can influence phenotypic expression, making repeated screening across multiple seasons essential for reliable trait identification.

Breeders use phenotypic screening to cull inferior plants, select breeding pairs, and verify that genetic crosses produce stable, predictable offspring. Rigorous phenotypic evaluation helps establish cultivar standards and supports seed production by ensuring only plants meeting target specifications contribute genetics to the next generation.
