2 populations. Two PSGMS loci, located on chromosomes 7 and 12, respectively, were identified in both crosses. The locus on chromosome 7 was the same as pms1, identified previously in a cross between an indica PSGMS line and an indica cultivar. The one on chromosome 12 was a new locus that we designated as pms3. Both loci had major effects on fertility and acted like a pair of classical duplicated genes in controlling male sterility. Comparison of the present finding with previous results indicated a complex genetic basis of PSGMS. The implications of such genetic complexity in breeding for PSGMS lines are also discussed.
