Some soybean mutants have been selected in our soybean mutation breeding program in recent years. They differed from parents (untreated) characterized by early maturity, high yield, good seed quality, and resistance to environmental stress. In the course of the selection, it was found that irradiation had obvious effects of induced variation upon the change of days to maturity and the improvement of the seed quality as well as its morphology.
