中文摘要:

燕麦孢囊线虫是小麦生产上的重要病原线虫。为筛选抗燕麦孢囊线虫的小麦种质资源，采用室内接种方法测试了104个国外小麦品种（系）和37个国内小麦品种对燕麦孢囊线虫的抗病性，并利用不同抗性评价标准在自然病田对37个国内小麦品种的抗病性进行了评价。室内接种试验表明，104份国外小麦品种（系）中有高抗品种（系）14个，中抗品种（系）12个，中感品种（系）27个，其他均属高感，37个国内参试品种均属感病品种。自然病田鉴定结果表明，采用不同的评价标准对37个国内品种的评价结果具有较大差异。依据Andersen等的评价标准，37个小麦品种中有7个品种表现感病，30个品种表现抗病，与室内接种测试结果差异较大；依据Ireholm的标准，仅良星66表现抗病，其他品种均表现感病，与室内测试结果接近；依据Soriano等的标准，37个品种均表现感病，与室内测试结果相同。建议在筛选抗孢囊线虫小麦资源时首先采用Andersen等的标准进行初筛，然后利用Soriano等的标准进行田间评价。

英文摘要:

Heterodera avenae is one of important pathogenic nematodes in wheat production. Resistance of 104 wheat germplasm abroad and 37 local cultivars to H. avenae was evaluated with inoculation technique and the resistance of 37 local cultivars was tested in the diseased field with three criteria for screening resistant germplasm. The results showed that 14 breeding lines were highly resistant, 12 breeding lines were moderately resistant, 27 breeding lines were moderately susceptible and the others were highly susceptible in all tested germplasm abroad, and all local cultivars were susceptible. The resistance of 37 local cultivars could significantly different with different criteria in the field test. Only 7 cultivars were resistant with Andersen and Andersen method. Liangxing 66 was resistant and all the rest were susceptible with Ireholm method. All the 37cultivars were susceptible with Soriano et al. method, which is same as the results in the inoculation test. We suggest the Andersen and Andersen method could be used for the preliminary screening for the resistance of wheat to H. avenae, and then Soriano et al. method was used for further test in the field.
