摘　　要：以水稻染色体片段代换系构建的分离群体为材料,利用微卫星标记(Simple sequence repeat,SSR)定位一个生育期基因,对水稻生育期基因的分子标记辅助选择进行了研究.结果表明,早熟显性基因(暂命名为Hd10-1)定位于第10染色体,SSR标记RM271和RM258之间,与RM271的遗传距离为1.90 cM,与RM258的遗传距离为8.40 cM,RM271与RM258位于Hd10-1的两侧.Gene mapping is the basis of molecular marker assistant selection（MAS）.In order to find the MAS basis of heading day gene,in this study,chromosome segment substitution line was used as material and one of dominant earliness genes was mapped with Simple sequence repeat（SSR） marlcer in rice.The results showed that the dominant earliness gene（Hd10-1） was located between SSR marker RM271 and RM258 on chromosome 10.The genetic distance was 1.90 cM from RM271 and 8.40 cM from RM258 respectively.The marker RM271 and RM258 were at the different sides of the Hd10-1.
