摘要
Abstract
A set of representative 146 adzuki (Vigna angularis var. angularis, and var. nipponensis)germplasm from 6 Asian countries traditionally for adzuki bean production, together with an out group stand-ard rice bean (Vigna umbellata), were analyzed by AFLP methodology using 12 informative primer pairs.313 unambiguous polymorphic bands were created. According to the dendrogram by cluster analysis based onAFLP banding, 143 of the accessions were distinct and revealed enough genetic diversity for identification andclassification of accessions within Vigna angularis. A neighbor joining tree was generated using newly devel-oped Innan's nucleotide diversity estimate from the AFLP data. From analysis, 7 distinct evolutionary groups,named as "Chinese cultivated", "Japanese cultivated", "Japanese complex-Korean cultivated", "Chinesewild", "China Taiwan wild", "Nepal-Bhutan cultivated" and "Hymalayan wild", were detected. Nucleotidediversity with geographical distribution of each group is discussed, regarding the evolutionary relationships be-tween wild and cultivated adzuki beans. The preliminary results indicated that cultivated adzuki bean should bedomesticated from at least 4 progenitors in at least 3 geographical origins.关键词
