Cbd Phenotypes

CBD phenotypes represent cannabis plants selectively bred to express elevated cannabidiol (CBD) levels while maintaining lower tetrahydrocannabinol (THC) concentrations. These genetic expressions emerged from both hemp-derived breeding programs and cannabis cultivars intentionally crossed for cannabinoid ratios. CBD phenotypes are commonly associated with lineages including Charlotte's Web, Cannatonic, and AC/DC, though the trait appears across diverse genetic backgrounds. Breeders working in this category typically employ marker-assisted selection and progeny testing to stabilize high-CBD expression across generations. The phenotypic stability of CBD can vary depending on underlying genotype and environmental factors, making consistent breeding selection important for commercial cultivation programs.

Breeders use CBD phenotypes as parent material to create 1:1 CBD:THC ratios, pure CBD cultivars, and chemically diverse F1 hybrids for research and agricultural markets. Stabilizing CBD expression requires understanding whether elevated levels are monogenic or polygenic, influencing breeding strategy and predictability in offspring.
