摘  要:
本研究用标记基因法对水稻农垦58S光敏感雄性不育基因进行染色体定位,结果表明光敏感雄性不育基因ms~(ph)分别与属于水稻连锁群Ⅰ等11个不同连锁群的U-1等28个标记基因表现为独立遗传,而与属于Ⅵ+Ⅸ连锁群的标记基因d-1连锁,估算二者之间的重组值为28.41±3.94%。推断光敏感雄性不育基因ms~(ph)位于西村氏的第二染色体上。

摘  要:
Chromosomal location of the photoperiod sensitive male genic sterile gene ms~h inNonkeng 58s were carried out by use of Marker Gene mothed. The results indicated thatgene ms~h showed independent of 27 marker genes belonging to the 11 Linkage groupsin rice plants respectively, but the linkage relation between gene ms~h and markergene d-1 belonging to Linkage Group Ⅵ+Ⅸ was detected, and the recombination valuebetween gene ms~h and marker gene d-1 was estimated at 28.41+3.94% from the se-gregations in F_2 by the method of maximum likelihood (Hanson and kramer 1950).From the resuters, It was concluded that the gene ms~h for photoperiod sensitive malegenic sterile was on Nishimura's chromosome 2.
