In order to understand the difference character of Japonica Rice resources in different regions, and provide the parent materials for the breeding of new varieties, from Yunnan, Sichuan Liangshan Prefecture and Japan some Japonica Rice germplasm resources were compared in the same field. By means of grey correlation analysis, with determination and comparison of multiple trait data, the resource characteristics of each species were comprehensively evaluated. The results show that there were differences in the characteristics of the varieties among different regions, the coexistence of advantages and disadvantages of each variety traits, yield traits were well correlated after ranking, and the correlation degree of the top of the output was low, which Y5 and B130 can increase production through improvement of cultivation technology, but also can be used as parents in breeding materials.
