摘　　要：采用浸根接种法鉴定不同向日葵种质资源对黄萎病的抗性差异。结果表明:40份供试向日葵品种依据抗性划分标准共分为3类,其中中抗品种有5份如:‘118’、‘新葵杂5号’等;低抗品种有8份如‘767’、‘KJ003’等;其余27份供试材料均呈现感病;没有鉴定出免疫和高抗的向日葵品种。The resistance of 40 different sunflower varieties to sunflower yellow wilt was tested via root dip inoculation method. The results suggested that all of the varieties tested could be divided into three groups. One group, including ‘118’ and ‘Xinkuiza 5’, showed moderate resistance to the sunflower yellow wilt; another group, including ‘767’ and ‘KJ003’, showed low resistance ; the last group showed susceptibility. There were no high resistance or immunity varieties among all of the materials tested.
