Rice blast, bacterial blight, Tryporyza incertulas and brown planthopper were major diseases and pests in Hainan province. In order to select multi-resistant rice varieties, the natural induced disease nursery identification and field spray and artificial inoculation identification were carried out with 7 new rice germplasms in Hainan. The results showed that the restorer line Haihui 1558 was resistance to rice blast and yellow rice borer, moderate resistance to bacterial blight, the restorer line Haihui 227 was resistance to bacterial blight and yellow rice borer, Hainonghong 1 was resistance to bacterial blight and middle resistance to rice blast, Haifengheinuo 2 was moderate resistance to bacterial blight and yellow rice borer.
