Abstract
Environment-sensitive genic male sterility (EGMS) Iine is useful in hybrid rice seed production. A parental line of rice, Norin-PL12, has a thermosensitive genic male sterility (TGMS) gene, tms-2. We estimated the locus of tms-2 using RFLP markers in F2 population derived from a cross between Norin-PL12 and Aus variety, Dular. As a result of quantitative trait locus (QTL) analysis using RFLP markers, it was revealed that the tms-2 is located between R643A and R1440 on chromosome 7.
