Frosted Phenotype

The Frosted Phenotype refers to cannabis plants exhibiting dense, visibly crystalline trichome coverage across flowers and sometimes leaves, creating a white or silvery appearance. This trait results from high trichome density and resin production rather than a single genetic marker, and appears across multiple strain families and lineages. Breeders working in this category often select parents with established frosted expression to concentrate the trait in offspring. Frosted phenotypes are commonly associated with resin-heavy cultivars, though visual frostiness alone does not indicate cannabinoid or terpene profile. The trait has become a selection target in commercial breeding programs focused on visual uniformity and resin yield. Preservation of frosted lines typically requires consistent phenotype monitoring across generations, as expression can vary under different environmental and

Breeders use frosted phenotypes as a visual marker for resin production capacity and as a selection criterion for uniform, commercially appealing crops. Maintaining frosted expression across generations requires deliberate parent selection and environmental consistency, making it a standard tracking trait in stabilized line development.
