Abstract
Using both inoculation of corn borer eggs in the field and PCR molecular test in laboratory, the corn borer resistance and the existence of Bt gene were identified in four corn inbred lines transferred with Bt gene. The results showed that the resistance to corn borer of the four transgenic inbred lines was increased obviously and the mean of worm tunnel length was significantly decreased by 49.71% compared with the negative controls, but the resistance level was not high as the positive control. Within each population of the four inbred lines, the resistance varied from high level of resistance to high level of sensitivity. Comparing with the negative controls, the tunnel length of the resistant plants was significantly decreased by 78.40%. DNA fragments specific for the Bt gene were detected from the four inbred lines by PCR. The inbred lines with Bt gene and high resistant to corn borer were selected. These inbred lines would facilitate breeding corn hybrid with Bt gene.
