The resistance to insects of the transf1enic tobacco cv 8611 expressing CPTI gene was tested. In comparitson with the control,mortality of the insects feedL1d on transgenic plants 8611.6 and 8611-11 reached 50%and 40%respectively,and the growth the:urvived insects were remarkeably inhibited.Under field condition,the in sects-damage index of progenies of 8611-6 and 8611-11 averaged 63.5%and 69.3/15 days after inoculation,averaf1ed 37.7%and 39.8%25 days after transplant,while that of the non-transformed control were 93.7%and 57%。 these results demonstrated that it was possible to obtain insect protection in transgenic tobacco expressing CPTI gene。
