The mutants were induced from seeds of soybean cultivars Jidou 1 and Jidou 6 with 0.8% ethyl methane sulphonate (EMS), and the related characters of their M2 generations were analysed. The results showed that the protein content negatively correlated with the oil content, it positively correlated with the plant height, 1000-seeds-weight, days of growing stage, days of flowering season, but negatively correlated with the ratio of seed weight to stem weight. The relation values of grain protein content in M2 and M3 presented significant variation. The mutant strain in which the grain protein content was high were selected from M2 to M3 generation. The grain protein content in the mutant lines selected was higher than that in the original varieties by 2.0%-3.0%
