Gene recombinations were conducted in initial stocks of male sterile sesame (Sesamum indicum) by population improvement. Many desirable variants appeared in the population. A male sterile line (ms86-1), which has good synthetical characteristics, 100 sterility and 50 frequency of the male sterile plants were bred through successive inbreeding and backcrossing. The male sterile line can be used in hybrid seed production. Study on morphology proved that the male abortion is complete and the female fertility is normal. The microspore of GMS aborted at the early nonvacuolate microspore stage. The male sterility is very stable in environments. According to the preliminary hereditary analysis, the sterility may be controlled by two allelic genes. The hybrid Yuzhi9 (ms86-1 X Danbackggae) has already been used in production
