禾谷孢囊线虫是麦类生产上的重要线虫。为筛选抗禾谷孢囊线虫的小麦和燕麦种质资源，以甘肃孢囊线虫群体为测试对象，采用室内接种法，通过测定单株白雌虫及孢囊数，对燕麦和小麦品种进行抗性分析。结果表明，在供试燕麦品种中无免疫品种，1个高抗品种(陇燕3号)，12个中抗品种。同样，在参试的小麦品种中无免疫品种，其中7个品种表现为中抗，包括定丰12号、西旱3号、武春8号等。可将高抗燕麦品种陇燕3号作为抗病亲本，用来培育和选择具有持久抗禾谷孢囊线虫的优良品种。

Cereal cyst nematodes (Heterodera avenae) is an important nematode in cereal crop production. In order to screen the germplasm resources of wheat and oat resistant to cereal cyst nematodes, the population of Gansu province cereal cyst nematodes was selected as experiment object, and the resistance of oat and wheat varieties was analyzed by measuring the number of white female and sporocysts per plant by indoor inoculation method. The results showed that there were no immune varieties in the oat varieties, 1 high resistant variety (Longyan 3) and 12 medium resistant varietieswere detected. Similarly, there were no immune varieties in the wheat varieties, and 7 varieties showed moderate resistance, including Dingfeng 12, Xishan 3 and Wuchun 8, etc. The high resistance oat cultivar Longyan 3 can be used as the disease-resistant parent to breed and select excellent varieties with persistent resistance to cereal cyst nematodes.
