Abstract: | Through the analysis of the anti-fusarium wilt of 207 materials in Jiangxi Province from 2010 to 2019 and the analysis of the anti-verticillium wilt disease of 87 materials in 2016-2019,the identification results showed that the anti-fusarium wilt level of the participating varieties was high,the high resistance and disease-resistant varieties accounted for 37.20%of the total participating varieties in 10 years,and the overall resistance to withering disease showed an upward trend;the tested varieties have a low level of resistance to verticillium wilt,and in the past 4 years,the disease-resistant varieties accounted for 17.24%of the tested varieties,a lack of high resistance varieties,but the overall resistance level to verticillium wilt disease in the last 2 years showed an overall upward trend.A total of 5 varieties resistant to fusarium wilt and verticillium wilt were screened out. |
