Cereal cyst nematodes (CCNs) are plant parasites that significantly limit global cereal production. The most frequently reported pathogenic species are Heterodera avenae, H. filipjevi, and H. latipons. One of the most cost-effective, environmentally friendly, and easily adopted control measures is the use of genetic host resistance, which maintains nematode populations below the economic damage threshold level. | Turkish Journal of Agriculture and Forestry Research Article Turk J Agric For (2014) 38: 180-186 © TÜBİTAK doi: Resistance of winter wheat to Heterodera filipjevi in Turkey 1, 1 2 3 1 Abdelfattah A.

The most frequently reported pathogenic species are Heterodera avenae, H. filipjevi, and H. latipons. One of the most cost-effective, environmentally friendly, and easily adopted control measures is the use of genetic host resistance, which maintains nematode populations below the economic damage threshold level. Many effective sources of resistance to CCNs have been identified in cereals; however, their effectiveness and usefulness is dependent on the interaction of the specific putative resistant accession and the CCN pathotype found in a specific region. In this study, 719 wheat lines from the Facultative and Winter Wheat Observation Nurseries, representing a broad geographical spectrum of breeding lines and varieties from Europe, Central Asia, and the International Winter Wheat Improvement Program, were screened against H. filipjevi under controlled conditions. The results indicated .
