Cannabis Domestication, Breeding History, Present-day Genetic Diversity, and Future Prospects Robert C. Clarke and Mark D. Merlin CRITICAL REVIEWS IN PLANT SCIENCES, 2016, VOL. 35, NOS. 5–6, 293–327 Doi : 10.1080/07352689.2016.1267498 ABSTRACT Humans and the Cannabis plant share an intimate history spanning millennia.

Cannabis breeders combined populations from widely divergent geographical regions and gene pools to develop economically valuable fiber, seed, and drug cultivars, [...]
