摘要
在由 2 10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 RFL P和 SSL P标记 ,在第 10染色体RZ811～RG5 6 1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 c M,对群体变异的贡献率为 43.2 %。应用极端群体分析法 。
In a population consisting of 210 test crosses of Xieqingzao A/(Xieqingzao B/Milyang 46)F 6 , 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.
