摘要

The semidwarf gene sd-g which has been used in indica rice breeding in southern China is a new one, nonallelic to sd-l. To map sd-g, an F_2 population derived from the cross between xinguiaishuangai and 02428 was constructed. The sd-g was roughly mapped between two mirosatellite markers RM440 and RM163, with genetic distances of 0.5 and 2.5 cM, respectively. Then nine new polymorphic microsatellite markers were developed in this region. The sd-g was further mapped between two microsatellite markers SSR5-1 and SSR5-51, with genetic distances of 0.1 and 0.3 cM, respectively, while cosegregated with SSR418. A BCA contig was found to span the sd-g locus, the region being delimited to 85 kb. This result was very useful for cloning of the sd-g gene.
