摘　　要：大豆高蛋白品种东农42和高脂肪品种东农163经NaN3进行诱变处理,在其后代品系中分别取58份和77份对农艺性状进行分析。结果表明:各品系单株粒数、单株荚数、虫食数的变异系数大,具有一定的选择潜力,而株高和主茎节数的变异系数较小;单株产量与株高、单株荚数、单株粒数呈极显著正相关;虫食率与单株荚数、单株粒数、单株粒重呈极显著正相关。High-protein soybean cultivar Dongnong42 and high-oil soybean cuhivar Dongnong163 were treated with NaN3 ,and agronomic character of 58 mutant lines derived from Dongnong42,77 lines from Dongnong163 were analyzed. The results indicated.a high level of variation was in seed number per plant, pod number per plant and number of seed with bug per plant, but a low level of variation was observed in plant height and node number of main stem; seed yield per plant had significant positive correlation with plant height,pod number per plant, and seed number per plant; number of seed with bug per plant had significant positive correlation with pod number per plant, seed number per plant and seed weight per plant.
