[Mapping of Sanming dominant genic male sterility gene in rice].
The mutant of "Sanming Dominant Genic Male Sterile Rice" was found from an F2 population of cross "SE2lS/Basmati370" by Sanming Institute of Agricultural Science in 2001. It has proven that the male sterility of this mutant is controlled by a dominant gene (named as SMS). By multiple backcrosses, this dominant male sterile allele was introduced into the genetic background of an indica rice cultivar Jiafuzhan (which was known as Jiabuyu). In order to map SMS, a mapping population was constructed by crossing Jiabuyu with a japonica cultivar Nipponbare and further crossing the F1 with Jiafuzhan. By bulked segregant analysis and linkage analysis using SSR and INDEL markers, SMS was mapped to a 99 kb interval between INDEL markers ZM30 and ZM9 on chromosome 8. This result will facilitate cloning of SMS.
