Abstract:
Core selection means a selected germplasm collection related to comprehensive breeding target traits，which is an applied concept based on “core collection”.The representative 154 landraces of summer-planted vegetable soybeans from major producing area in China were chosen and tested in a randomized block design with two replications.The pod length，pod width，pod thickness，100 fresh pod weight，100 fresh seed weight，number of seeds per pod and soluble sugar content were evaluated.Their phenotypic values were calculated for Euclidean distances among accessions，and then the Ward’s method of hierarchical cluster was used for cluster analysis.According to the dendrogram and analysis of variance (ANOVA)，the core selection composed of 47 landraces was established through choosing the two groups with better performances.The results showed that the landraces chosen from the core selection could retain comprehensively better traits than those from single elite traits.
