摘　　要：籽粒色泽是小豆商品性的重要特征之一,研究其基因遗传信息对小豆粒色改良具有指导意义。本文应用作物数量性状主基因+多基因混合遗传模型对JN001(红粒)×B47(白粒)杂交组合的F2:3单世代的籽粒色泽明度指数(L*)、红度指数(a*)和黄度指数(b*)进行分离分析。结果表明:(1)初步推测控制小豆籽粒的L*、a*、b*性状的基因对数均为2对主基因;(2)L*、b*的主基因遗传率较高,分别为78.44%和52.18%,而a*的主基因遗传率中等,为38.77%。Seed color is one of the important commodity features of adzuki bean. It is of practical guiding significance to the formulation of seed color breeding in adzuki bean to probe into the genetic messages of its genes. The genetic parameters of brightness index （ L^＊ ） ,red index （ a^＊ ） and yellow index（b^＊ ） of seed color in F2：3 progenies from one hybridized combina- tion of adzuki bean were estimated by utilizing segregation analysis method of the mixed genetic model for major gene plus polygene of quantity traits in crop. The results showed that ： （ 1 ） It was deduced preliminarily that the number of couple of genes controlling respectively the seed traits of L^＊ , a^＊ and b^＊ was 2 couples of major genes; （2） The habitability of major genes of L^＊ , a^＊ and b^＊ was 78.44% ,38. 77% and 52.18% , respectively.
