14份CIMMYT玉米群体材料配合力分析及利用价值评价

Combining Ability and Utilizing Value of 14 CIMMYT Maize Population Materials

对来自CIMMYT的14份玉米群体,按不完全双列杂交组配56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、结穗率、穗行数、行粒数、倒伏率、百粒重、单株产量8个性状的GCA、SCA和TCA。结果表明,群体Pob43、pob28、pob21、pob45在东北春玉米区应用前景较好,黄早四/pob43、丹340/pob28、丹340/pob45、掖478/pob21、丹340/pob21是较好的杂交模式。

For 14 CIMMYT maize population 56 hybridized combinations were made by using incomplete dual cross. GCA SCA TCA of plant height silking period ear percentage rows per ear kernels per row lodging percentage 100-grain weight yield per plant were analyzed. The results indicated that applying prospects of pob43 pob28 pob21 pob45 were better Huangzao 4/pob43 Dan 340/pob28 Dan 340/pob28 Dan340/pob45 Ye478/pob21 Dan340/pob21 were better cross models.
