| 摘要: |
| 红米因其独特的营养价值日益受到人们关注.红米由两对非同源染色体上的Rc、Rd显性基因控制,且Rc、Rd基因同时存在时,水稻才表现为红米表型.本研究分别在Rc和rc等位基因以及Rd和rd等位基因影响性状的关键性位点上建立了分子标记:Rc(+5150)和Rd(+276).检测结果显示:这2个分子标记可以分别用来区别控制红米性状的Rc/rc和Rd/rd基因型.开展本研究,为今后利用分子标记辅助快速有效地选育各类红米水稻新品种研究提供了重要的帮助. |

| Abstract: |
| Red rice attracts people′s attention greatly for its special nutritional value.Red pericarp phenotype of rice is controlled by two pairs of dominant genes,Rc and Rd,on non-homologous chromosomes,and rice pericarp will be red only while Rc and Rd genes are both present.In this study we developed two molecular markers,namely Rc(+5150)and Rd(+276),directly on key loci of Rc/rc allele and Rd/rd allele affecting the rice pericarp color.The results show that the two molecular markers could discriminate the different genotypes of Rc/rc and Rd/rd.This study provides an important help for breeding red rice new varieties quickly and efficiently by using molecular marker-assisted selection. |
