摘 要：
为了解不同地区粳稻资源的性状差异,并为新品种选育提供亲本材料,将来自中国云南、四川凉山州和日本的部分粳稻种质资源进行同田比较。通过对多个性状数据的测定比较,应用灰色关联度分析法分析,综合评价各品种资源性状。研究结果表明:不同地区间的品种资源性状各有差异,各品种性状优缺点共存,产量性状好的关联度排名较后,而关联度排名靠前的产量又较低,其中Y5和B130可以通过栽培技术的改进来提高产量,也可作为育种的亲本材料。

摘 要：
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.
