摘要
本研究将获得的导入慈姑胰蛋白酶抑制基因的新疆栽培品种（品系）和导入Ｂｔ基因的抗蚜品种，采用室内叶片饲喂法，进行了抗棉铃虫幼虫的鉴定和抗性评定。在供试的１３个Ｂｔ材料中，其中有８个材料的抗虫性优于中国农科院培育的Ｒ９３－６，表现为超高抗至中抗；导入ＡＰＩＡ的４个棉株，与对照新陆早４号相比，其中３株表现为抗，１株为中抗。采用田间罩笼法观察棉蚜在抗虫棉上的增殖量，结果为川１０９和川７７蚜量低于对照，而导入ＡＰＩＡ的棉株效果不明显。
By the method of leaf feeding in laboratory,an evaluation was made on the APIA transgenic cotton varieties or lines and aphid resistant Bt cotton varieties. Among thirteen Bt cotton lines, eight lines were more resistant to the cotton bollworm by medium to high resistance than R93 6 which was bred by the Chinease Acadamy of Agricultural Sciences. Among 4 APIA transgenic plants, three show resistance while one medium resistance when compared with CK“Xinluzao 4”.In terms of reproductive capacity of cotton aphids inside the cages in the fields, “Chuan 109”and“Chuan 77”have fewer aphids than CK while APIA transgenic plants were not different from CK.
