Abstract

Root lesion nematodes (RLNs), Pratylenchus thornei Sher & Allen, 1953 and Pratylenchus neglectus (Rensch, 1924) (Tylenchida: Pratylenchidae) are important plant-parasitic nematodes that cause economic yield losses in wheat cropping systems worldwide. The use of resistant and tolerant cultivars is the most effective method to control these nematodes in wheat. There are currently no commercial wheat cultivars identified as completely resistant to the RLN species. The aim of this research was to evaluate 19 Turkish spring wheat cultivars for reaction to P. thornei and P. neglectus under in-vitro conditions over 16 weeks in 2019. In the result of the study, nine wheat cultivars (Adana99, Ata89, Bürküt, Cumhuriyet75, Gönen98, Marmara86, Meta2002, Troya and Uludağ) were found to have moderate resistance against P. thornei, whereas five wheat cultivars (Adana99, Alibey, Ata89, Ceyhan99 and Uludağ) were moderately resistant to P. neglectus. The study also showed that Adana99, Ata89 and Uludağ are resistant to both nematode species, and these cultivars, thus, are considered to be excellent sources of genes for further development RLN resistant commercial wheat cultivars.

小麦品种对Pratylenchus thornei-Sher&Allen，1953和Praylenchus neglectus（Rensch，1924）的寄主适应性（Tylenchida:Pratylenchidae）

根损线虫(RLNs)， Pratylenchus thornei Sher & Allen, 1953和Pratylenchus negectus (Rensch, 1924) (tylenchia: Pratylenchidae)是在世界范围内造成小麦种植系统经济产量损失的重要植物寄生线虫。选育耐药品种是防治小麦线虫最有效的方法。目前还没有商业小麦品种被鉴定为完全抗RLN品种。本研究旨在评估19个土耳其春小麦品种在2019年16周的体外条件下对thornei和P.忽视的反应。结果表明，9个小麦品种(Adana99、Ata89、b rk t、Cumhuriyet75、Gönen98、Marmara86、Meta2002、Troya和uludakul)对thornetus具有中等抗性，5个小麦品种(Adana99、Alibey、Ata89、Ceyhan99和uludakul)对漠漠病小麦具有中等抗性。该研究还表明，Adana99、Ata89和uludazu对这两种线虫都具有抗性，因此，这些品种被认为是进一步培育抗RLN商品小麦品种的优良基因来源。

期刊介绍： The Turkish Journal of Entomology is a quarterly journal which has been published by Entomological Society. Turkish Journal of Entomology publishes original research articles in the fields of entomology and agricultural zoology in English. Authors whose native language is not English should have their paper edited professionally prior to submission. Before preparing the typescript for submission, examine the format of manuscripts already published in Turkish Journal of Entomology. According to TJE rules, biological observations made in one location in only one-year, short notes in which the first record of a single species in Turkey is announced, and research which is older than five years will not be accepted for publication unless it forms part of a longitudinal study.
