Determination of the pathotype group of Heterodera filipjevi (Madzhidov, 1981) population and resistance of H. populations against wheat genotypes

WOS: 000286013600009Determination of the pathotype group of Heterodera filipjevi (Madzhidov, 1981) population and resistance of H. populations against wheat genotypes The international pathotype differential lines were used to determine the pathotype group of Heterodera filipjevi (Madzhidov, 1981) Stelter population collected from Yozgat province, Turkey. The reaction of H. filipjevi Yozgat population on the differential lines indicated they were different than the other 5 known H. filipjevi pathotypes. Futherwork was conducted with these H. filipjevi populations to assess the usabilitiy of known published Cereal Cyst Nematode (CCN) resistance genes against a closely related species and pathotypes of Heterodera avenae Wollenweber, 1924. Several of these wheat lines known to possess resistance against H. avenae pathotypes and also the Haymana H. filipjevi populations did not exhibit resistance against H. filipjevi Yozgat populations
