Thcv Phenotypes

THCV (tetrahydrocannabivarin) phenotypes represent plant expressions selected or bred to produce elevated levels of this minor cannabinoid. THCV is structurally distinct from THC, with a propyl side chain rather than pentyl, and occurs naturally in certain cannabis populations—notably landraces from Africa and parts of Asia. Breeders working in this category focus on stabilizing THCV-dominant or THCV-rich genotypes through selective breeding and backcrossing. THCV phenotypes are commonly associated with specific terpene profiles and growth patterns that correlate with cannabinoid expression. These plants remain relatively uncommon in seed catalogs and require careful breeding documentation, as THCV content varies significantly across cultivars and environmental conditions.

Breeders target THCV phenotypes through marker-assisted selection and backcrossing proven parents, often working with African and Asian heritage genetics. THCV expression is heritable but polygenic, making stabilization a multi-generation project requiring cannabinoid testing to confirm phenotypic consistency.
