稻瘟病、白叶枯病、稻飞虱和三化螟是海南水稻生产的主要病虫害。为选育多抗水稻品种，本研究对选育的7个地方稻新种质进行了自然诱发病圃鉴定及田间喷雾和人工接种鉴定。结果表明，恢复系海恢1558抗稻瘟病和三化螟，中抗白叶枯病；恢复系海恢227抗白叶枯病和三化螟；红米海农红1号抗白叶枯病，中抗稻瘟病；海丰黑糯2号中抗白叶枯病和三化螟。

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.
