Abstract：The article deals with researches on obtaining new strains of highly resistance to create new hybrid rice with fine quality and strong resistance to rice blast germ through backcross between the lysozyme gene donor-transformed ZH-9(R) and general types 9311, MH63, 288, E32 and PA64s in Hunan. The results are as follow: Hybrid offspring were notably more resistant to rice blast than their parents. In the five parent indica rices, MH63 turned out to be superior to the others for that its transferring generations displayed well and stable in resistance and agronomic characters; Positive plants of PCR are 269 from 353 that screening from all of transferring generations, which is 76.20%; Contrast to resistance identification result, the ration of likeness reaches 94.05%.
