| 摘 要： | 采用增广NCⅡ设计，以5个高品质陆地棉品种（系）为母本，5个转基因抗虫棉品种（系）为父本组配的25个杂交组合为材料，研究主要株型性状的遗传效应、杂种优势及与产量性状的相关性。结果表明，株高、始果枝高、果枝数和果节数的平均中亲优势较小，但不同组合间差异较大，均符合加性遗传模型。遗传相关分析表明，株高与株铃数、单株皮棉重呈极显著正相关；果枝数与株铃数呈极显著正相关，与铃重呈极显著负相关；果节数与株铃数、衣分和单株皮棉重呈显著正相关。株型性状与产量性状间的关联性主要是由果节数与株铃数、铃重的相关引起。研究结果为高品质抗虫棉理想株型性状的选育与调控具有一定的指导意义。

| Abstract: | The objectives of this study were to evaluate the genetic effects and heterosis of plant type characters in hybrids by crossing five Bacillus thuringiensis (Bt) transgenic cotton varieties as male parent and five high quality upland cotton varieties as female parent, and analyze the relationships between plant type characters and yield traits. The results showed the mean mid-parent heterosis of plant height, height of the first fruiting branch, fruiting branch number and fruiting node number were fairly low... |
