Abstract By using transgenically bred borer resisting rice as parent, ternary hybrid rice maintainer line and restoring line and two-way hybrid rice light and temperature sensitive nuclear sterile line and restoring line as recurrent parent, and through continuous backcross, antibiotic resistance screening of hybrid progeny and molecular biological test, the Bt maintainer line, Bt nuclear sterile line and Bt restoring line with basically the same characteristic as original parent and carrying cryIAb gene are obtained. The present invention can reduce the production cost of hybrid rice, prevent the environmental pollution caused by borer killing pesticide and raise yield.
