通过田间自然寄生试验,鉴定了2个向日葵新品种对列当的抗性。结果表明,向日葵新品种TP3313列当寄生率为0%,抗寄生指数为1,为免疫品种,其他病虫害发生为害较轻,产量为261.1 kg/667m~2,具有较高的推广应用价值;TP3314向日葵列当的寄生率为0.4%,寄生指数为0.99,为高抗品种。但向日葵菌核病发生较重,产量为219.6 kg/667m~2,在生产应用过程中,应注意向日葵菌核病的防控。
Through natural parasitic field experiments, two new sunflower varieties were identified resistance to the column. The results showed that the parasitism rate of the new sunflower variety TP3313 was 0% and the anti-parasitic index was 1, which was an immune species. The other pests and diseases were less harmful and the yield was 261.1 kg / 667m ~ 2, which had a high value for popularization and application. TP3314 The parasitism rate of sunflower was 0.4%, and the parasitic index was 0.99, which was a high resistant variety. However, severe occurrence of sclerotinia in sunflower, the yield of 219.6 kg / 667m ~ 2, in the production and application process, should pay attention to Sunflower sclerotinia prevention and control.
