Phylogenetic relationships among cultivated landraces and natural populations of wild subspecies of Tartary buckwheat were investigated at the individual level by constructing a phylogenetic tree based on amplified fragment length polymorphism (AFLP) markers. Seven individuals from seven cultivated landraces and 35 individuals from 21 natural populations of wild subspecies were utilized for AFLP analyses. Three groups were recognized: (1) all cultivated landraces and wild subspecies from northern Pakistan, central and eastern Tibet, and northwestern Yunnan, (2) wild subspecies from central and southern Sichuan, (3) wild subspecies from northern Sichuan and eastern Tibet. It was concluded that cultivated Tartary buckwheat probably originated in eastern Tibet or northwestern Yunnan in China.
