本试验用~(60)Coγ射线辐照 A3681高粱种籽,在 M_2代筛选出了高于对照的高蛋白突变体82—22(13.39%),82—63(13.71%)和82—66(14.49%)及高赖氨酸突变体82—35(0.22%)、82—37(0.22%)和82—41(0.28%)。蛋白质的变异系数为15.40%,变幅是6.98—14.49%,变幅差是7.51%。赖氨酸的变异系数是12.64,变幅是0.15—0.28%,变幅差是0.13%,均高于对照。 In this experiment, the sorghum seeds of A3681 were irradiated with ~ (60) Coγ ray and the high protein mutants 82-22 (13.39%), 82-63 (13.71%) and 82-66 14.49%) and high lysine mutants 82-35 (0.22%), 82-37 (0.22%) and 82-41 (0.28%). The coefficient of variation of protein is 15.40%, the amplitude is 6.98-14.49%, the difference is 7.51%. The coefficient of variation of lysine was 12.64, the amplitude was 0.15-0.28%, and the difference of amplitude was 0.13%, all higher than the control.
