应用化学诱变剂处理大豆种子,对M_1代植株的生育及形态均有强烈的抑制作用.M_1代所产生的形态变异主要是由于化学物质扰乱了植株生理而产生生理损伤所致.在M_2代植株各性状中以分枝数、株高、单株荚数的遗传变异系数较大,说明这些性状选择的潜力是大的,通过选择容易达到预期目标.诱变M_3代绝大多数性状仍在分离.加强选择,能选出早熟、大粒、农艺性状好、丰产的新品系.
The application of chemical mutagens to treat soybean seeds strongly inhibited the growth and morphology of M_1 generation plants.The morphological changes of M_1 generation were mainly caused by the physiological damage caused by chemical substances disturbing the plant physiology.In the M_2 generation The genetic variation coefficient of branches, plant height and pods per plant were larger, indicating that the potential for selection of these traits was large, and it was easy to reach the expected target by selection.Most of the traits in M_3 were still Separation. Strengthen the choice, can be elected precocious, large grain, agronomic traits, high yield of new lines.
