Genetic diversity of cowpea landraces in Zhejiang Province,China
Zhejiang is one of the main cowpea producing areas in China.To systematically sort out and identify the cowpea landraces in Zhejiang Province,220 cowpea accessions collected in Zhejiang Province in multi-years were e-valuated on 21 important traits in the field.The results showed that these landraces had large phenotypic variation,and they could be divided into four clusters according to their phenotype data,of which,Cluster Ⅲ displayed the similar phenotypes with the current released cultivars,indicating that these accessions had high values for cowpea breeding.Using the cowpea specific core single nucleotide polymorphisms(SNPs),the genotypes of 220 landraces were also identified and their DNA fingerprinting was constructed.Based on their genotype data,these accessions were also divided into four subpopulations,and subpopulationⅢ showed the longest pods.In summary,the genetic diversity of Zhejiang cowpea landraces was evaluated from different perspectives,and the results would provide a sci-entific basis for cowpea germplasm enhancement and new cultivars development.
