摘  要:
以02428、8504和CPSLO 17与籼型测验种南京11、IR36、测49和模型测验种巴利拉、秋光、丰锦测交,F_1杂种的小穗育性为78.8%~97.9%,其平均值02428为90.2%,8504为82.4%,CPSLO 17为90.9%。以CPSLO 17作对照,研究了02428、8504的广亲和性遗传,推测它们的广亲和性遗传都是由一对主基因控制的,广亲和基因与色素原基因C~+连锁位于第Ⅰ连锁群上,遗传规律符合单位点孢子体-配子体互作模式,并受微效基因的修饰作用。

摘  要:
Rice cultivars 02428, 8504, and CPSLO17 were crossed with three indica testers, i. e. Nanjing 11, IR36, Ce49 and three japonica testers, i. e. Balila, Akihikari, Toyonishiki, the spikelet fer- tility of F_1 hybrids is 78.7%~97.9%, the mean spikelet fertility of F_1 hybrids included 02428, 8504 and CPSLO17 as one parent is 90.2%, 82.4% and 90.9% respectively. It suggests that the inheritance of wide compatibility in these WCVs might be controlled by a single major gene modified by minor genes, and the wide compatibility gene not only link with chromogen gene C~+ located in linkage group I, but also its in- heritance fits to one-locus sporo-gametophytic interaction model.
