| 摘 要： | 本研究对转觑和GNA双价基因后代植株，经南繁加代、抗虫检测、自交、单株和株系选择、纤维品质测定和产量比较试验，选育出双价转基因抗虫棉种质系BGsm16。该种质系高抗棉铃虫等鳞翅目害虫，对蚜虫有一定的抑制作用，抗虫性稳定且不随世代的增加而减弱，衣分高（48．0％左右），配合力好，结铃性强，通风透光，皮棉产量比受体材料苏棉16号增产11．1％，品质两者相当。与其配置的杂交棉组合衣分高，丰产性好，品质高于对照南农8号，有着很强的杂种优势。转＆和GNA双价基因抗虫棉种质系BGsm16的成功选育，加强转基因棉花的抗虫能力，拓宽了抗虫谱，并有助于延缓害虫对抗虫棉产生抗（耐）性；同时改变了传统对常规抗虫棉衣分低的认识，丰富了抗虫棉种质资源，对选育高衣分杂交抗虫棉有良好的应用前景。

| Abstract: | In the article,transgenic Bt+GNA insect-resistant cotton plants were studied and new transgenic Bt+GNA insect-resistant cotton germplasm line "BGsm16" with high lint percentage was derived by speeding up generation in Hainan province,insect-resistant tests,selection of individual plants and lines,determination of fiber quality and comparative experiment of yield.It showed high resistance against bollworm larvae(Helicoverpa armigera),inhibition effect on the development of aphid populations,and stability of ... |
