Abstract: In a population consisting of 210 test crosses of Xieqingzao A/(Xieqingzao B/Milyang 46)F6 , RFLP and SSLP markers were assayed to determine restorer genes for dwarf wild abortive cytoplasmic male sterility(CMS) in rice. A major gene explaining 43.2% of the total phenotypic variation was mapped in the interval RZ811-RG561 on chromosome 10, with the most likely position being 4.0 cM to RZ811. The same result was obtained by linkage analysis based on sterile extremes and fertile extremes.

Key words: cytoplasmic male sterility, restorer gene, gene mapping, rice

摘要： 在由210个测交组合组成的协青早A/(协青早B/密阳46)F6群体中，应用RFLP和SSLP标记，在第10染色体RZ811～RG561区间，定位了1个控制水稻矮败型细胞质雄性不育育性恢复的主效基因，与RZ811相距 4.0 cM，对群体变异的贡献率为 43.2%。应用极端群体分析法，其定位结果一致。
