小豆种质资源粒色与生育期的相关性分析

摘要

以我国小豆主产区的107份小豆种质资源为研究对象，采用1976年国际照明委员会规定的L*a*b*表色系，研究了107份红粒小豆种质资源粒色与生育期的相关性。结果表明：小豆籽粒颜色的亮度值（L*）、红度值（a*）和艳度值（b*）均与生育期呈显著的正相关，且三者对生育期的综合效应顺序为b*＞a*＞L*，表明小豆籽粒越鲜艳，生育期就越长。在育种过程中，如以短生育期为目标，则应选择籽粒颜色稍暗的材料作亲本；如以粒色鲜亮为目标，则应选择生育期较长的材料作亲本。本研究可为小豆育种过程中亲本的选择提供理论参考。%Correlation between grain color and growth period of 107 red tablets adzuki bean germplasm resources was studied using L*a*b*color system regulated by CIE.The results showed that the L*, a*and b* of adzuki bean grain color had significant positive correlations with the growth period, the order of the comprehensive effect for growth period was b* >a* >L*, which showed that adzuki bean seed was more bright-coloured, the growth period was longer.In the breeding process, such with short growth period as the goal the grain darker color materials should be chosen as the parents, such with grain color bright as the target the longer growth period materials should be chosen as the parents.This provided a certain reference value for parental choice in the breeding process of adzuki bean.
