Abstract

Two F2 populations with different kinds of spike derived from maize male sterility materials RP(3)195 (A) x S37 (inbred line) ,which had been sib-bred for many generations,were used for sterility analysis and gene location. There were 138 and 247 plants in the two F2 populations respectively. Among the 326 pairs of microsatellite primers selected,56 were found polymorphic. Linkage analysis of F2 populations with the 56 pairs of primers showed that microsatellite markers bnlg197 and umc1012 were linked with the male sterility gene. The genetic distance between marker bnlgl97 and the male sterility gene in the two different F2 populations were 7 cM and 14.5 cM respectively. The genetic distance between marker umc1012 and the male sterility gene in the 138 plants was 28.5 cM. Thus the male sterility gene was located on chromosome 3L.

[利用微卫星标记定位航天诱导玉米雄性不育基因]。
以兄弟姐妹杂交多代的玉米雄性不育材料RP(3)195 (A) × S37(自交系)为材料,对2个不同穗型的F2群体进行了不育性分析和基因定位。2个F2群体分别有138株和247株。在326对微卫星引物中,56对存在多态性。56对引物对F2群体的连锁分析表明,微卫星标记bnlg197和umc1012与雄性不育基因连锁。在2个F2群体中,标记bnlgl97与雄性不育基因的遗传距离分别为7 cM和14.5 cM。138株中标记umc1012与雄性不育基因的遗传距离为28.5 cM。因此,雄性不育基因位于染色体3L上。
