Determination of plant parasitic nematodes associated with chickpea in Turkey

A survey of plant parasitic nematodes associated with chickpea was conducted in the chickpea growing areas of Turkey including 37 districts in 17 provinces during spring and summer of 2014-2016. A total of 211 soil and root samples were collected. Nematodes were extracted from soil by different extraction methods to ensure all kinds of nematode groups. Nematodes were identified using morphological and morphometric features. In addition, Pratylenchus spp. Filipjev, 1936 were determined using species-specific primers. Ditylenchus dipsaci (Kühn, 1857), Pratylenchus neglectus (Rensch, 1924) and Pratylenchus thornei Sher & Allen, 1953 were the most common of the plant parasitic nematodes associated with chickpea in the areas surveyed. Pratylenchus neglectus , P. penetrans (Cobb, 1917) and P. thornei were present in almost all samples. In descending order, P. thornei , P. neglectus and D. dipsaci were detected in 179, 138 and 95 in samples (84, 65 and 45% of samples, respectively). Other nematodes found at lower frequency were species of Aphelenchus Bastian, 1965, Criconemoides Taylor, 1936 , Dorylaimida species , Helicotylenchus Steiner, 1945, Merlinius Siddiqi, 1970, Paratrophurus Arias, 1970 , Paratylenchus Micoletzky, 1922 , Trophurus Loof, 1957, Tylenchorhynchus Cobb, 1930, Tylenchus Bastian, 1865 and Xiphinema Cobb, 1913.
