摘　　要：以5个具有抗虫基因的棉花品种(系)与6个非抗虫棉品种(系)为材料,按NCII方法配制杂交组合,对30个组合的F1代及其中三个组合的F2代的主要性状进行杂种优势分析。结果表明,F1各主要性状具有较强的杂种优势,单株皮棉量和株铃数的中亲优势分别为22.48%和16.58%;绒长和单株皮棉产量的竞争优势分别为11.90%和10.07%。F2代主要产量性状有明显杂种优势,生产上仍有一定利用价值。Crosses were made by NCII design,using five-resistant cotton cultivars(or lines)as famale parents and six traditional cotton cultivars(or lines)as male parents,to analyze the main yield characters of 30 F1 hybrid combinations.The results showed that the heterosis of F1 hybrid was higher,the average mid-parent heterosis of lint cotton yield and The number of bell were 22.48% and 16.58%;cashmere long and lint cotton yield had the higest competitive heterosis,and the numeric were 11.90% and 10.07%.F2 generatio...
