Abstract: The field performance resistance of 20 main rice varieties to diseases and insect pests were analyzed, by using the method of natural induction and field survey on the occurrence of diseases and insect pests. The results showed that the overall resistance of the main varieties to several common diseases and insect pests of rice was not ideal, and the varieties of Guangliangyou 476, Ezhong 5, Huanghuazhan, Tianyou huazhan and C-Liangyouhuazhan had better resistance to diseases and insect pests, and the occurrence and damage degree of diseases and insect pests were relatively light, which was suitable for popularizing planting in Hubei province. However, the planting area of Shenliangyou 5814 was suggested to be reduced and controlled as far as possible due to the relatively heavy disease and insect occurrence.
