利用树上套笼接虫方法 ,对 18个转Bt基因和凝集素基因的 74 1杨无性系进行了抗桑天牛特性鉴定 ,初步确定了P10、CC11、CC2 5、CC5 3等 4个抗天牛无性系和 1个轻感天牛无性系P2 2。
In this study, 18 clones of Bt gene and lectin gene of 18 clones were identified by the method of tree cages in the tree. The resistance of 4 clones to P10, CC11, CC2 5 and CC5 3 was initially determined Cerambycidae and a susceptible Celastrus californicus P2 2.
