| 摘 要： | 目的]对EMS化学诱变小豆京农6号M3代材料进行筛选鉴定,以期获得有潜力、有价值的变异材料。方法]利用EMS处理小豆京农6号,对M3代叶形变异率、变异类型、农艺性状及产量构成因素进行分析。结果]浓度0.9%EMS处理24h,叶形变异类型最为丰富,且突变频率最高。综合叶形突变体农艺性状分析,各种突变类型总体表现为小叶〉肾叶〉叶缺刻〉小密叶〉剑叶〉鸡爪叶。小叶、肾叶突变体具有较低株高、紧凑直立、多分枝、多荚、单株产量高、百粒重高等优良性状。结论]该研究筛选的突变体可为小豆育种及遗传学研究提供有价值的材料。

| Abstract: | Objective]The aim was to screen and identify M3 progenies of Jingnong 6 variety induced by EMS chemical mutagenesis and obtain potential,valuable mutation material. Method]Azuki bean cultivar Jingnong 6 was treated by EMS. The mutation rate,mutation types,agronomic traits and yield components of the leaf mutants were analyzed. Result]The results showed that there is the most abundant variational type of leaf and the highest frequency of mutation treated with 0.9% EMS for 24 hours. Comprehensive analysis ... |
