摘要
对萍乡显性核不育水稻的遗传规律进行了研究,结果表明该不育材料的育性是由两对显性核基因Ms和Rf互作控制的。其中Ms是显性不育基因,Rf是显性上位基因。两者共同存在时,显性上位基因能抑制显性不育基因的表达,从而使有性表现可育。其不育群体的遗传组成为Msmsrfrf+msmsrfrf或MSMSrfrf+MsMRfRf,恢复系基因型为msmsRfRf。
The genetics of Pingxiang dominant genic male sterile rice was studied, the results show that its fertility is controlled by two pairs of dominant genes Ms and Rf which have epistatic interaction. Ms is a dominant sterile gene, Rf is a dominant epistatic gene. When both genes are present in the same individual, the latter can inhibit expression of the former, so that the individual changes from being sterile to being fertile. The genetic components of sterile population are Msmsrfrf+ msmsrfrf or MsMsrfrf + MsMsRfRf. The restorer line genotype is msmsRfRf.
