| 摘 要： | 本研究用0.2%和0.4%的秋水仙素溶液浸泡小豆京农6号(JN6)种子12 h,M_1成株率分别为26.7%和3.5%,变异率为1.24%和1.59%,结果表明处理浓度越大,成株率越小、变异率越大.0.2%秋水仙素处理12 h为较佳处理,但0.4%处理的变异类型相对丰富.M_2代与对照相比,单株粒数在5%水平上达到显著差异,百粒重在1%水平达到极显著差异;M_3代百粒重与对照相比在1%水平达到极显著差异,诱变后代中筛选出了3个高产优良株系.在M_3代共筛选到263个叶色、叶形、蔓生、多分枝、黑荚、浅红和深红粒色、大粒及早晚熟等性状变异突变体.叶形有剑叶、小密叶、肾叶突变类型;叶色有深绿、浅绿、黄化、黄斑叶变异类型.早熟和晚熟变异株分别比对照早熟10～15 d和晚熟7～10 d.

| Abstract: | In this study,we soaked the seeds of Jinnong 6 variety in adzuki bean in 0.2% and 0.4% colchicines solution to treat for 12 hours,respectively.Results from experiments showed that the rates of surviving plants in the M1 generation were 26.7% and 3.5%,while the variation rates were 1.24% and 1.59%.The results demonstrated that the concentrations of colchicines would be great,the ratio of surviving plants would be small and the ratio of variation would also be great.The treatment of 0.2% colchicines is more u... |
