Abstract: To provide information for parental selection and germplasm improvement, forty-seven adzuki bean native varieties from Sichuan province(Table 1) were investigated based on 15 morphological characters. The results are as follows:①The growth habit of the adzuki bean germplasm resources in Sichuan province is mainly upright habit;②There is higher variability of some characters related to grain yield per plant such as plant height, number of ramification, pod/plant, seeds/pod and 100-seed weight, number of ramification, and so on;③The morphological diversity of the adzuki bean germplasm resources is higher, and its average diversity index is 1.529;④There is the remarkably positive correlation between growth period and grain yield, it is the same among pod length, pods/plant, 100-seed weight and grain yield/plant. These results suggest that the adzuki bean germplasm resources in Sichuan province can be used as parent materials for breeding program.
