淡绿叶标记光-温敏核不育水稻叶色及育性的遗传分析

以2个淡绿叶色标记的粳稻光温敏核不育系（TS1、TS3）和4个正常叶色可育系杂交，对其F2、F3群体进行叶色和育性遗传分析，结果表明，淡绿叶遗传受2对基因控制，其中1对基因对另1对基因有抑制作用；不育性的遗传由2对主效基因及一些微效多基因共同影响；控制叶色和育性的基因各自独立遗传。应用累积分布曲线基因分析方法证明TS

Genetic Analysis of Leaf Color and Sterility in Photo-thermoperiod Sensitive Genic Male Sterile Rice with the Pale-green Leaf Marker

The inheritance analysis of leaf color and male sterility were made in F 2 and F 3 populations from two PGMS lines with the pale-green leaf marker (TS1, TS3) and four different restorer lines in japonica rice. The results showed that the pale-green leaf color was controlled by two pairs of genes, of which there was a suppressing gene, and that the male sterility was controlled together by two major effect genes with several minor genes. Both the leaf color and male fertility were inherited independently. By using the method of cumulative distribution curve we proves that the inheritance model of pale-green leaves in F 3 of the combination TS1/Waa24 gives good agreement with the two genotypes theory curve of AB. The authors think that the pale-green leave as a marker trait is caused by lacking of the dominance-suppressing gene (I).
