Abstract：In order to determine the virus isolates types of wheat yellow mosaic disease in Zhumadian of Henan province, and evaluate resistance of winter wheat cultivars currently promoted in Zhumadian to wheat yellow mosaic disease,from 2013 to 2014 a total of 13 wheat samples collected from different fields in Zhumadian were investigated using ELISA, and under the same field experiment conditions, the resistance of 12 common wheat cultivars was tested in the disease nursery and non-disease nursery at Suiping county. The results showed that wheat yellow mosaic virus(WYMV) was found in 4 sites(30. 8%of the 13 sites) ,and Chinese wheat mosaic virus( CWMV) was not detected in all the sites. In 12 wheat varieties tested, two cultivars ( Yunong 416 and Hengguan 35, 16. 7% of those tested ) were highly resistant to WYMV,two cultivars ( Fanmai 8 and Huayu 198,16. 7% of those tested) were moderately resistant or moderately susceptible,and the remaining cultivars (66. 6% of those tested) were highly susceptible. There was a big difference in the wheat yield and yield three factors between different cultivars. The results indicate that WYMV has a certain range of distribution in Zhumadian area, and CWMV is not detected yet. Yunong 416 and Hengguan 35 have a certain resistance to wheat yellow mosaic disease in the region.
