The cereal cyst nematodes (CCN) severely threaten wheat production in many cereal-growing areas around the world as well as in Turkey. The screening of wheat and/or barley varieties for characterization of resistance against CCN is a critical step to develop resistant varieties. The present study describes the phenotyping and genotyping resistance situation of indigenous wheat varieties against one Kilis population of Heterodera latipons. Some barley varieties were also included in the phenotyping test. Among the phenotypically tested wheat varieties, Adana99, Menemen, Troya, Izmir, and Kakliç88 were highly resistant (females/plant < 3) to Kilis population whereas no barley variety was resistant. The microsatellite markers linked to Cre1, Cre3, and Cre5 were detected in the resistant varieties Adana99, Izmir, Ceyhan99, and Ata81, while the presence of Cre8 and CreX genes could not be detected in the varieties tested. As expected, no Cre marker was detected in any barley varieties. The presence of the resistance genes Cre1 and Cre5 in wheat does not adequately suppress the reproduction of H. latipons in Ceyhan99 and Ata81 varieties. The Cre3 gene detected using Xgwm301 marker provides resistance to H. latipons in İzmir and Ziyabey98 wheat varieties. Some Cre genes were detected in some wheat varieties regardless of whether they are phenotypically resistant or not; however, no correlation was found between the presence of any marker and phenotypic resistance.
