对国内辐射诱变育成的63个玉米突变系进行了连续3年的统一观察鉴定。研究评价了可供进一步在育种上应用的突变系:具有较高特殊配合力的早熟硬粒型突变系原武02、原齐123;早熟突变系鲁原γ M5-1 6、原辐27;矮秆突变系华风100,鲁原375、原辐17、原辐26;综合性状良好的突变系176;株形好的突变系原辐17.辐外16及原齐722;具有较好一般配合力的鲁原11-24731和鲁原1333以及特殊配合力较高的鲁原111,鲁原8-5。来源于西南玉米区的部分系因生态条件的不同,表现晚熟,甚至不能成熟,但表现抗大斑病和青枯病,可通过进一步诱变,改变光周期反应,作抗病亲本利用。
Sixty-three maize mutants bred by domestic radiation mutation were identified for three consecutive years. The study evaluated and evaluated the mutant lines that could be used for further breeding: the early maturity hard grain type mutant Wuyuan 02 with original special combining ability; the early mature mutant Luyuan γ M5-1 6 with the original special breadth 27; Stalk mutations were the Chinese wind 100, Luyuan 375, the original spokes 17, the original spokes 26; good overall character of the mutant line 176; good shape mutant line of the original spokes 17. Radiation 16 and the original Qi 722; with better general coordination Lu original power of 11-24731 and Lu original 1333 and special with a higher Luyuan 111, Lu original 8-5. Due to the difference of ecological conditions, some of the maize derived from Southwest China are late-maturing or even immature, but their resistance to leaf spot and bacterial wilt may be further mutagenized to change their photoperiodic response and be used as resistant parents.
