An applied core collation of munbean was established to accelerate the application of germplasm in breeding. This core subset includes the elite germplsam in the national gene bank, the cultivars that are or had been cultivated widely, and the parents mostly used in breeding and their elite lines. The evaluation of agronomic traits showed that the core samples had high variations in phenotypes. Cluster analysis based on agronomic traits can divide the core samples into four groups, but the groups did not show relationship with the origins of accessions. Comparison among different origins of data showed that there were different among the evaluations of both in qualitative and quantitative traits, but the variations in quantitative traits are agreeable with the aims of genetic improvement of mungbean, indicating the core collection be efficiently used in breeding and production.
