Te morphological characters and morphometric features of second-stage juveniles and cysts showed the presence of 3 Heterodera species: H. avenae , H. flipjevi, and H. latipons. All morphological values of these distinct populations were very similar to those previously described for these species. Genetic variation was observed among the identifed cyst nematode species H. avenae, H. flipjevi, and H. latipons. Intraspecifc polymorphism was observed within H. avenae and H. latipons but not in H. flipjevi populations. Molecular analysis using ITS regions of rDNA confrmed the identities of the 3 Heterodera species. According to our results, 75% of isolates were identifed as H. avenae , 15% as H. latipons, and 10% as H. flipjevi.eninfo:eu-repo/semantics/openAccessCereal Cyst NematodeMorphologySequencesPhylogeneticArticle39191982-s2.0-84918821810Q2TR-DizinIDWOS:000346850400011Q2
