Popis:	For the first time, the b/c intron of the nad1 gene was characterized in 13 species of Fagopyrum and the applicability of the intron was demonstrated for identification of buckwheat species. The length of the b/c intron of the nad1 gene varied from 1217 bp in F. tataricum and F. cymosum to 1239 bp in F. capillatum. Species-specific SNPs and indels were identified. The genus phylogeny that was determined with the molecular approach correlated with phylogenetic data that are based on morphological characteristics. The NJ and MP dendrograms revealed distinct division of the analyzed species into two main groups, cymosum and urophyllum. The species of the urophyllum group were characterized by the presence of several synapomorphic substitutions and indels, including the insertion of 11 nucleotides, which is flanked by direct repeats.
