Abstract: Mass selection (MS) and single character bulk selection (CS) were used for improvement of six characters of base population B1 which was composed of the sterile plant of fourteen parents transferred by Taigu sterile wheat. Base population B2 which was composed of four parents above was conducted only with backcross mass selection (BS). The results showed that no matter which selective method was used, there were greater selected effect for grain protein yield/plant, kernel number/spike, 100-kernel weight and grain yield/ plant, all of them were above 5 percent. For the improvement of single character, there was the greatest selected effect with CS, but for the improvement of population, MS was the best, and it was favourable to the greater of population variance, CS was not. For the selected phase, it was selected with the greatest selective effects in the first, second and third cycle for CS, MS and BS respectively. In the paper the use of recurrent selection method for wheat was analyzed by using Taigu single dominant male sterile gene.

Key words: Taigu male sterile wheat, Recurrent selection, Base population, Genetic advance
