Evaluation and Identification of Resistance to Diseases and Pests for Rice Varieties in Hainan

[Objectives]This study was conducted to select multi-resistant rice varieties in Hainan.[Methods]Seven new rice germplasms were identified by naturally induced disease nursery,field spraying and artificial inoculation.[Results]The restorer line Haihui 1558 was resistant to the dominant races ZB and ZC of rice blast and Tryporyza incertulas,and moderately resistant to pathotype IV of bacterial blight.The restorer line Haihui 227 was resistant to pathotype IV of bacterial blight and T.incertulas.Red rice Hainonghong 1 was resistant to pathotype IV of bacterial blight,and moderately resistant to the dominant races ZB and ZC of rice blast.Black glutinous rice Haifengheinuo 2 was moderately resistant to pathotypes IV of bacterial blight and T.incertulas.[Conclusions]The study provides reference for utilization of rice breeding on resistance to diseases and pests.
