国内几个主要玉米群体材料配合力分析及利用价值评价

Combining Ability and Utilizing Value of Some Main Domestic Maize Population Materials

对国内12份有代表性的玉米群体材料,按不完全双列杂交组配48个杂交组合。采用完全随机区组设计进行试验,分析了株高、抽丝期、穗长、穗行数、行粒数、倒伏率、百粒重、单株产量等8个性状的GCA、SCA、TCA。结果表明群体吉综A、辽旅综、中综3号、豫综5号、WBMC4、中综4号在东北春玉米区应用前景较好,丹340/WBMC4、丹340/中综3号、丹340/中综4号、掖478/辽旅综、掖478/吉综A、丹340/吉综A是较好的杂交模式。

For 12 domestic maize population,48 hybridized combinations were made by using incomplete dual cross .GCA,SCA,TCA of plant height, silking period, ear length, rows per ear, kernels per row, lodging percentage, 100-grain weight, yield per plant were analyzed. The results indicated that applying prospect of Jizong A, Liaolvzong, Zhongzong3, Yuzong5, WBM-C4, Zhongzong4 were better; Dan 340/WBM-C4, Dan 340/Zhongzong3, Dan340/Zhongzong4,Ye478/Liaolvzong, Ye478/Jizong A, Dan340/Jizong A were better cross models.
