在五个组合的测交 F_1,F_2、F_3和 B_1F_1中研究了普里美比和加恢061两个恢复系对 ms 农大139、ms 12057和 ms 斯达台三个 T 型不育系的育性恢复遗传.结果表明恢复力的遗传符合 wilson(1968)和 sage(1972)的三基因累加显性学说,即三个基因分别以完全显性和部分显性对育性恢复作出不同贡献。三个基因的累加作用产生了所观察到的表现型。对(ms 139×加恢061)_(-2)的一个 F_3系衍生的 F_4系统群的育性分离作了 X~2测验,验证了 F_3和 F_2的基因型.
The fertility of three T-CMS lines, ms Nongda 139, ms 12057 and ms Starota were studied in the five combinations of F_1, F_2, F_3 and B_1F_1. The results showed that the inheritance of restoring force accorded with the triple gene dominance theory of wilson (1968) and sage (1972), that is, the three genes respectively contribute to fertility restoration with full dominance and partial dominance respectively. The additive effect of the three genes produced the observed phenotype. The fertility of F_4 system derived from a F_3 system derived from (ms139 × Jiahuai 061) _ (-2) was tested by X ~ 2 test to verify the genotypes of F_3 and F_2.
