Abstract:

In this paper, firstly, we review research progress of transgenic maize with insect resistant, classify and summarize main approaches of maize transformation with Bt toxin protein gene and screening of transgenic lines, then the bioassay for insect resistance and evaluation and utilization of genetic stability are introduced, too. Finally, we discuss the technical difficulties and prospect of transgenic maize with insect resistant. We hold that in order to promote better development of maize transformation with Bt toxin protein gene, the key technologies must be further study positively.
