Abstract

Guangzhan 63S, a photoperiodthermosensitive genic male sterile (PTGMS) line, was one of the most widely used PTGMS lines in twoline indica hybrid rice breeding system in China. Genetic analysis indicated that the sterility of Guangzhan 63S was controlled by a single recessive gene using the F2 population derived from a cross between the Guangzhan 63S and Han 1587. Molecular mapping was performed on the F2 mapping population using SSR and InDel markers and bulkedsegregant analysis(BSA). The PTGMS21 was restricted to a 390kb region on chromosome 2 between the markers S24 and S227, at genetic distances of 0.5 cM and 1.1 cM, respectively, and cosegregated with S224.

Key words： photoperiodthermosensitive genic male sterility; genetic analysis; molecular mapping
