| 摘 要： | R68是带有金黄色颖壳和节间标记的籼稻恢复系。对来源于组合中9A/R68 的F2群体的遗传分析表明，R68的金黄色颖壳和节间性状由1对隐性基因控制。利用SSR分子标记，采用隐性群体分析法，把金黄色颖壳和节间基因定位在第3染色体上，位于RM1230、RM7000和RM227、RM514之间，遗传距离分别为8.7、3.3、2.7和4.7 cM,暂将该基因命名为 gh 5。 |
| 关 键 词： | 水稻 金黄色颖壳和节间基因 |

| Abstract: | Genetic analyses were carried out for an F2 population derived from the cross between a cytoplasmic male sterile line Zhong 9A and R68, an indica restorer line with a gold hull and internode marker. The results indicated that the gold hull and internode trait was controlled by one recessive gene. Relying on simple sequence repeat (SSR) markers and recessive class analysis method, the gold hull and internode gene (gh) was mapped at an interval on rice chromosome 3 flanked by RM1230 and RM7000 on one side, as well as RM227 and RM514 on the otherside, at distances of 8.7, 3.3, 2.7 and 4.7 cM, respectively. The newly mapped gene was tentatively designated to be gh-5. |
