Sticky Phenotype Expression

Sticky phenotype expression refers to the observable trait of elevated resin production and surface tackiness in cannabis plants, often correlating with higher terpene concentrations and cannabinoid density. This characteristic is heritable and appears across multiple strain families, though expression varies significantly based on genetic background and environmental conditions during cultivation. Breeders working in this category have documented sticky phenotypes in both indica and sativa lineages, suggesting polygenic inheritance patterns. The trait is commonly associated with plants displaying visibly crystalline or glandular trichome coverage, though resin composition itself varies independently of surface stickiness.

Breeders select for sticky phenotypes to maintain or enhance resin production within established lines, using visual and tactile assessment as early-stage selection markers. This trait serves as a practical breeding indicator, though breeders recognize that stickiness alone does not guarantee specific terpene profiles or cannabinoid ratios.
