Abstract: Soybean mutant population was constructed by treating the seeds of soybean “Nannong 86-4” with 60Co γ rays and EMS respectively. In M3 generations, 40 mutants of leaf, stalk, flower, seed and cotyledon were obtained by treatment of 60Co γ rays, and 145 mutants by EMS. In addition, the mutants of protein and oil contents were obtained; there were 47 mutants with more than 5 percentages on protein content and 5 mutants with more than 5 percentages on total protein and oil content compared with control. These mutants will serve as new germplasm in breeding. The mutant population will be useful to study functional genomics in soybean.

Key words: Soybean, 60Co γ rays, EMS, Mutant
