Özet

Root lesion nematodes, Pratylenchus spp. feeds on plants root and causes wounds provide a means of entry for soilborne pathogen. It is known that the using of resistant/tolerant wheat varieties is the most effective method in order to control nematodes in wheat cultivation. In this study, the resistance of 82 bread wheat varieties grown in Turkey were investigated against root lesion nematodes, Pratylenchus thornei and P. neglectus, in-vitro conditions. At the end of this study, no resistant wheat genotype against Pratylenchus thornei and P. neglectus was found. However, it was found that 29 varieties moderately resistant, 44 varieties moderately susceptible, 9 varieties susceptible against P. thornei and 37 varieties moderately resistant, 38 varieties moderately susceptible, 7 varieties susceptible against P. neglectus. Additionally, 14 wheat varieties were moderately resistant against both P. thornei and P. neglectus. Among the tested wheat varieties, Uzunyayla, Atli, Yayla 305 and Harmankaya showed higher performance than CROC_1/AE. SQUARROSA(224)//OPATA) variety, therefore it is suggested that these varieties should be incorporated into national wheat breeding programs.
