Özet
Kök yara nematodları, Pratylenchus spp. bitkilerin kökünde beslenir ve toprak kökenli patojenlerin bitkiye girişini sağlayan yaralanmalara sebep olur. Buğday yetiştiriciliğinde nematodlara karşı en etkin mücadele yöntemi dayanıklı/ tolerant çeşitlerin kullanımı olarak bilinmektedir. Bu çalışmada, Türkiye’de yetiştiriciliği yapılan 82 adet ekmeklik buğday çeşidinin kök yara nematodları, Pratylenchus thornei ve P. neglectus’a karşı in vitro koşullarda dayanıklılıkları araştırılmıştır. Çalışma sonucunda denemeye alınan buğday genotiplerinden P. thornei ve P. neglectus’a karşı dayanıklı çeşide rastlanılmamıştır. Bununla birlikte, P. thornei’ye karşı 29 çeşit orta dayanıklı, 44 çeşit orta hassas ve 9 çeşidin hassas olduğu ve P. neglectus’a karşı ise 37 çeşit orta dayanıklı, 38 çeşit orta hassas ve 7 çeşidin hassas olduğu saptanmıştır. Ayrıca, 14 adet buğday çeşidi hem P. thornei’ ye hem de P. neglectus’a karşı orta derecede dayanıklı bulunmuştur. Denemeye alınan çeşitler içerisinde Uzunyayla, Atlı, Yayla 305 ve Harmankaya buğday çeşitleri CROC_1/AE. SQUARROSA(224)//OPATA) buğday çeşidine göre daha yüksek performans gösterdiği için ulusal ıslah programlarına dahil edilmesi önerilmektedir.
Root lesion nematodes, Pratylenchus spp. feeds on plants root and causes wounds provide a means of entry for soil- borne 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, Atlı, 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.
