Thc Dominant Type I

Type I cannabis plants produce predominantly THC-dominant cannabinoid profiles, with THC concentrations typically exceeding 0.5% dry weight while CBD remains minimal or trace. This classification emerged from early cannabinoid research (Elsohly & Slade, 1990s onwards) and became a standardized descriptor as testing infrastructure developed. Type I genetics represent the majority of modern recreational breeding lineages, though cannabinoid ratios vary considerably between individual plants and cultivars. Breeders distinguish Type I from Type II (balanced THC/CBD) and Type III (CBD-dominant) primarily through cannabinoid quantification via HPLC or similar analytical methods. Understanding Type I classification helps seed companies and cultivators align genetics with intended breeding objectives and market applications.

Type I classification serves as a foundational selection criterion in breeding programs targeting high-THC cultivars. Breeders use cannabinoid phenotyping to stabilize Type I expression and develop F1 hybrids or elite lines with consistent THC-dominant profiles across generations.
