A key based on cyst and juvenile characters is given for identification of 12 valid Heterodera species in the H. avenae group. A compendium providing the most important diagnostic characters for use in identification of species is included as a supplement to the key. Cyst characters are most useful for separating species; these include shape, color, cyst wall pattern, fenestration, vulval slit length, and the posterior cone including presence or absence of bullae and underbridge. Also useful… 
Molecular and morphological characterisation of the Heterodera avenae species complex (Tylenchida: Heteroderidae)
TLDR
Morphometrical and ITS-rDNA sequence analyses revealed that the Chinese cereal cyst nematode is different from other H. avenae populations infecting cereals and is related to H. pratensis.
A reference of identification keys to plant-parasitic nematodes (Nematoda: Tylenchida\ Tylenchomorpha)
The present review has documented a list of keys for identifying plant-parasitic nematodes at different taxonomic levels including superfamily, family, subfamily, genus, and species. It was compiled
Distinguishing Heterodera filipjevi and H. avenae using polymerase chain reaction-restriction fragment length polymorphism and cyst morphology.
TLDR
Using polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) of internal transcribed spacer (ITS)-ribosomal (r)DNA with up to six restriction endonucleases will improve detection and identification efficiencies for cereal cyst nematodes in wheat fields.
Molecular Polymorphism and Morphometrics of Species of the Heterodera avenae Group in Syria and Turkey.
TLDR
The results showed a clear separation of the three cyst nematode species on cereal using a conventional method for classification and molecular tests, and confirmed the congruence between genetics and morphological traits.
Characterization of cereal cyst nematodes (Heterodera spp.) in Morocco based on morphology, morphometrics and rDNA-ITS sequence analysisis
Morphological and molecular diversity among 11 populations of cereal cyst nematodes from different wheat production areas in Morocco was investigated using light microscopy, species-specific primers,
Morphological and molecular identification of cyst nematode species (Heterodera spp.) in Algerian cereal fields
TLDR
The results of this study are of great value to breeding programs and extension services, where they will contribute to the design of control measures to keep damaging nematodes in check.
Species-Specific PCR Assays for Differentiating Heterodera filipjevi and H. avenae.
TLDR
This is the first report of a species-specific ITS PCR assay to detect and identify H. filipjevi and H. avenae, which will enhance diagnosis of cereal cyst nematode species in infested fields.
Nematodes which Challenge Global Wheat Production
TLDR
Effects of cereal cyst (Heterodera) and rootlesion (Pratylenchus) nematodes on wheat are difficult to identify and control, and molecular markers have been developed to identify genes and quantitative trait loci for resistance in seedlings.
Morphological and molecular characterisation of Heterodera filipjevi (Madzhidov, 1981) from the Slovak Republic
TLDR
The results of the phylogenetic analysis of the ITS rRNA gene sequences confirmed the species identification and phylogenetic relationship of H. filipjevi with other Heterodera species and showed the close similarity between the Slovakian and Chinese samples, which differed by a single nucleotide and clustered together.

Heterodera spinicauda sp. n. (Nematoda: Heteroderidae) from mud flats in the Netherlands, with a key to the species of the H. avenae group
TLDR
This new Heterodera species, with its bifenestrate vulval region and short vulval slit, belongs to the H. avenae group and is unique because of: an inconspicuous vulval cone, giving the initial impression that the cysts are spherical.
