摘　　要：以大豆合丰25为试验材料,经过航天搭载与^(60)Co-γ辐射的复合诱变处理,对M2代4个株系的主要农艺性状进行研究。结果表明经过复合诱变后大豆群体株高、底荚高度、主茎节数、单株荚数、单株粒数等主要农艺性状发生不同程度的变化,存在着与对照达到显著或极显著的株系;只有1个株系主茎节数存在单株变异率,其它株系主茎节数单株变异不明显;株高、底荚高度、单株英数、单株粒数等农艺性状均有不同程度的单株变异率,可以为大豆种质创新所利用。In the research for four main strains agronomic characters of M2, using space launch and gamma radiation ^60Co-γcomposite process for the test materials Soybean HeFeng25 are analyzed. The results shown that the plant height, the first pod hight, number of node, number of plant pod and seed were significant or of highly significant level. There were only one strain has mutation rate. Other strains on number of node variation is not obvious. Plant hight, the first pod hight, number of plant pod, number of plant seed have different levels of mutation rate. It can be used for soybean breeding.
