摘要
1987～1989年,用CmstChris单体系统为母本与恢复系R_(4489)杂交,杂种F_1代通过镜检,查出单体。对单体F_2代单株套袋并进行育性调查及统计分析,结果表明:R_(4489)有两个恢复基因,一个主要恢复基因位于1B 染色体上,另一个次要恢复基因位于4B 染色体上,还有一个育性抑制基因位于6D染色体上。
A monosomic set of CmstChris are crossed(as females)with restorer R_(4489)Monosomic plants in F_1 hybrids and seed set data from bagged spikes of F_2plants from F_1 monosomic bybrids used to identify progenies with restorer ge-nes are inspected and analysed.The results indicate that R_(4489)has two rest-orer genes-one major and one minor,the former is located on chromosome 1Bthe latter on 4B and an addilional inhibitor gene on 6B.
