Abstract:

The correlation between seed color and leaf color of 126 shares of red-seed cultivated adzuki bean germplasm resources was studied with the CIE L*a*b* color order system. The results showed that seed color was closely related with leaf color for the sort of secondary early-maturing and middle-maturing adzuki bean in Beijing area. Degree of correlation between seed color and leaf color was higher in the peak period of bearing pods than in other period. It would be of more possibility to obtain the materials of fine seed color by selecting seed color indirectly by leaf color, selecting the plants of dim brightness and light green leaf in peak period of bearing pods.

Key words: adzuki bean, seed color, leaf color, correlation, germplasm resource

摘要：

采用CIE L*a*b*表色系研究126份红粒小豆栽培种质资源的粒色与叶色相关性。结果表明,北京地区中早熟和中熟类型小豆粒色与叶色存在较密切的关系;小豆盛荚期叶色与粒色相关度较高;通过叶色间接选择粒色,盛荚期选择叶片亮度较暗、绿色浅的植株,获得粒色优良材料的可能性较大。
