摘　　要：采用不同光照反应类型的大豆品种进行杂交，对其Ｆ２代进行短光照诱导，研究短光照对大豆杂交Ｆ２代群体变异的影响，并通过杂交育种等手段选育光钝感大豆新种质。试验结果表明，不同类型的杂交组合在Ｆ２代进行短光照处理后，其群体的变异明显不同；双亲均为不敏感的组合Ｃ１，其Ｖｅ－Ｒ１的天数、株高和主茎节数处理与对照相比差异不大；而亲本之一为光照敏感材料的组合Ｃ２和Ｃ３却表现出差异很大；选育出哈９１－７１１６、哈９２－４４６５和哈９２－４４９８对光照反应不敏感的大豆新种质。Effect of short daylength on variation of F 2 soybean population was studied and the procedure and method for wide adaptation germplasm breeding were discussed in this paper. The results showed that variation in F 2 was varied in different crosses after short daylength induction. V e-R 8 period, plant height and nodes of stem can be applied in photoperiodical breeding as identification traits. Ha 91-7116, Ha 92-4465 and Ha 92-4498 were developed as photoperiod insensitive germplasms.
