摘　　要：研究了外源抗虫基因对转基因抗虫杂交棉正反交的影响。结果表明,转基因抗虫杂交棉的产量比常规杂交棉有了显著提高,但对纤维品质的影响不大;外源基因在母本中或父本中对转基因抗虫杂交棉的影响也不显著,对纤维品质的影响除比强度外也没有明显的差异,说明遗传性状的控制主要受核基因控制。The effect of foreign gene on cotton reciprocal cross was studied.The results showed that yield traits of hybrid cotton with foreign gene was higher than common hybrid cotton, but it had no distinct effect on quality traits. Ever foreign gene in mother or father had also not effect on yield traits and quality traits except strength and elongation. It proved that nuclear inheritance was predominated.
