Genetic Diversity Analysis and Comprehensive Evaluation of Rural Kidney Bean in Heilongjiang Province
The genetic diversity and phenotypic traits of 331 rural kidney bean resources collected in Heilongjiang Province were used as the test materials by statistical analysis,correlation analysis,cluster analysis and principal component analysis,and the results were used for resources were comprehensive evaluation of resources,in order to provide abundant breeding materials for the breeding of new varieties of rural kidney bean.The results showed that the genetic diversity of the 331 resources was rich,and the coefficient of variation was between 14.90%and 44.51%.The coefficient variation of 7 traits were more than 20%,such as PL,PT,TPL,TPB,NSCPP,NSPP,TKW.Clustering could divide resources into 2 categories and 6 groups.Five principal components were extracted with contribution rates of 24.695%,16.359%,12.152%,9.752%and 8.168%,respectively,and the cumulative contribution rate was 71.127%.The varieties z158,z155,z085,z094,z271,z224,z016,z162,z097 and z209 can be used as superior resources.
