Intraspecific rDNA restriction fragment length polymorphism of Heterodera avenae

摘要

Heterodera avenae group sensu lato presently contains eleven valid species: H. arenaria, H. aucklandica, H. avenae, H. bifenestra, H. filipjevi, H. hordicalis, H. iri, H. latipons, H. mani, H. spinicauda and H. turcomanica and several undescribed species. H. avenae group so called 'species complex' grouping several sibling species. Identification species of this group based on differences in morphological and morphometrical characters requires a lot of skill and is often inconclusive for individuals.
