Abstract

Cereal cyst nematodes (Heterodera avenae group) are important pests of wheat; they include the three most important species of cereal cyst nematodes: Heterodera avenae Wollenweber, H. latipons Franklin and H. filipjevi (Madzhidov) in Turkey that were determined in different wheat growing areas. It was reported that Mediterranean cereal cyst nematode, Heterodera latipons which is widely found in the centre of the durum wheat growing area -South-eastern Anatolia region-in our country was reaching the economical threshold in many locations. It is known that the use of resistant/tolerant wheat varieties is the most effective controlling method against cyst nematodes in the wheat cultivation. Nowadays, nine different resistance genes (Cre genes), which are transferred from wild wheat species to wheat cultivated forms are available. In this study, the efficiency of the resistance gene, Cre1, against the population of H. latipons from Gaziantep (Karkamis) was investigated. In the study, 38 genotypes carrying Cre1 gene and 26 genomes lacking resistance genes; this gives a total 64 wheat genotypes which are produced by parental crossing of SILVERSTAR containing the resistance gene, Cre1, in its genome, SOKOLL, CALINGIRI, GOLDMARKER, CROC_1/AE.SQUARROSA(224)//OPATA, FRAME, STYLET and PASTOR were used against H. latipons in the experiment. Among the 64 genotypes; 20 were resistant, 32 were moderately resistant and 12 were moderately susceptible to the nematode. Ten resistant, 20 moderately resistant and 8 moderately susceptible lines were determined against H. latipons that these 38 lines carried the Cre1 gene in their genome. Within this study, the resistant gene, Cre1, was not found to be completely resistant against H. latipons, but its 78% efficiency rate was found to be successful: therefore, it was concluded that it can be used against H. latipons in national wheat breeding programs. Furthermore, PASTOR, SOKOLL and CROC_1/AE.SQUARROSA(224)//OPATA wheat genotypes were determined as good resistance source against H. latipons.
