| 中文摘要: |
| 为了明确河北省小麦主产区禾谷孢囊线虫的致病类型，采用27个国际鉴别寄主品种和2个感病小麦品种‘石新733’和‘温麦4’对河北省邯郸、保定、任丘和唐山的4个禾谷孢囊线虫群体致病型进行了鉴定。依据Andersen等鉴别标准，4个群体的致病型不同于国际上已命名的16个禾谷孢囊线虫致病型。唐山群体为一个致病型，它的致病型和山西太谷、安徽固镇群体的致病型相似；邯郸群体、保定群体和任丘群体的致病型属于同一致病型，这3个群体的致病型和定州群体的致病型很接近。对照小麦品种‘石新733’和‘温麦4’对4个禾谷孢囊线虫群体均表现感病。 |
| 英文摘要: |
| The pathotypes of four populations of the cereal cyst nematode Heterodera avenae Wollenweber in Handan, Baoding, Renqiu and Tangshan, the primary wheat production areas in Hebei Province, were identified using 27 cultivars of international differential host set and two susceptible cultivars, namely ‘Shixin733’ and ‘Wenmai 4’. The results showed that the pathotypes of these populations were different from the 16 pathotypes which had been nominated. Tangshan population was a pathotype that was similar to the pathotype reported from Taigu population in Shanxi and Guzhen population in Anhui. Handan population, Baoding population and Renqiu population belonged to the same pathotype, similar to the pathotype reported from Dingzhou population. Cultivar ‘Shixin733’ and cultivar ‘Wenmai 4’ used as the control were susceptible to all four populations. |
