对以无短绒材料为母本配置的7个转基因抗虫杂交组合进行了杂种优势和综合性状表现研究。研究结果表明:7个杂交组合霜前皮棉杂种优势突出,早熟性较好,衣分、铃重和子指比较协调;纤维长度较长,比强度中等,麦克隆值偏高,整齐度好,伸长率中等;生育期为中熟类型;具有株高中等、果枝始节位略高、结铃性较好的特性;高抗枯萎病,耐黄萎病;抗棉铃虫。
The study of heterosis and comprehensive trait performance of 7 transgenic insect-resistant hybrid combinations with no ringlets as the female parent was conducted. The results showed that the seven hybrid combinations had prominent heterosis of lint before frost, with good precociousness, better coordination of lint percentage, boll weight and daughter index; longer fiber length, medium specific strength, higher wheat micronaire value, good uniformity, Medium growth rate, medium growth rate and medium maturity stage. It has the characteristics of medium plant height, slightly high starting point of fruiting branches and good boll resistance. It is highly resistant to Fusarium wilt, Verticillium wilt resistance and bollworm resistance.
