摘      要：The species Vigna unguiculata L.(Walp),commonly known as cowpea,is a multi-purpose legume that has been selected into three subspecies that are divided into grain,fodder and pod(yardlong bean)***,genetic bases for distinctions are not well *** purpose of this study was to apply genotyping-by-sequencing(GBS)and current reference genome for *** to distinguish three subspecies and identify signatures of *** collection of 130 accessions included 128 cultivated from:1)***,fodder type;2)***,pod vegetable type;and 3)***,grain *** wilds genotypes from *** and ***,were used to anchor phylogeny.A total of 11,083 highly informative single nucleotide polymorphisms(SNPs)were *** accessions showed distinct genetic fingerprints and were separated from cultivated *** component analysis showed closer relationship between *** and *** compared to *** differentiation of cultivated subspecies(with Fixation Index,FST)indicated the existence of discrete signatures of *** work clarifies the population structure,phylogeny,and domestication of cultivated ***,significant genetic differences between grain and pod vegetable types can provide valuable information for future breeding in three cowpea groups.
