  • Association analysis of resistance to cereal cyst nematodes (Heterodera avenae) and root lesion nematodes (Pratylenchus neglectus and P. thornei) in CIMMYT advanced spring wheat lines for semi-arid conditions
    (Japanese Society of Breeding, 2016) Dababat, A.A.; Gomez-Becerra, H.F.; Erginbas Orakci, G.; Dreisigacker, S.; Imren, M.; Toktay, H.; Elekcioglu, I.H.; Tesfamariam Mekete; Nicol, J.M.; Ansari, O.; Ogbonnaya, F.C.
    To identify loci linked to nematode resistance genes, a total of 126 of CIMMYT advanced spring wheat lines adapted to semi-arid conditions were screened for resistance to Heterodera avenae, Pratylenchus neglectus, and P. thornei, of which 107 lines were genotyped with 1,310 DArT. Association of DArT markers with nematode response was analyzed using the general linear model. Results showed that 11 markers were associated with resistance to H. avenae (pathotype Ha21), 25 markers with resistance to P. neglectus, and 9 significant markers were identified to be linked with resistance to P. thornei. In this work we confirmed that chromosome 4A (~90–105 cM) can be a source of resistance to P. thornei as has been recently reported. Other significant markers were also identified on chromosomal regions where no resistant genes have been reported for both nematodes species. These novel QTL were mapped to chromosomes 5A, 6A, and 7A for H. avenae; on chromosomes 1A, 1B, 3A, 3B, 6B, 7AS, and 7D for P. neglectus; and on chromosomes 1D, 2A, and 5B for P. thornei and represent potentially new loci linked to resistance that may be useful for selecting parents and deploying resistance into elite germplasm adapted to regions where nematodes are causing problem.

  • Cereal Cyst Nematodes: an unnoticed threat to global cereal production
    (CGIAR, 2011) Dababat, A.A.; Pariyar, S.R.; Nicol, J.M.; Duveiller, E.
    Nematodes are among the earliest recognized parasites of wheat that occur worldwide in nearly all environments. A loss of 10% of world crop production has been estimated as a result of plant nematode damage (Whitehead 1998). The cereal cyst nematodes (CCN

  • Report: ATSE crawford fund - CIMMYT master class in soil borne pathogens of cereals
    (CIMMYT, 2003) Nicol, J.M.
    The course on Soil Borne Pathogens of Cereals was suggested by Dr Julie Nicol, CIMMYT Pathologist, who is based in the CIMMYT Regional office in Turkey. Dr Hans Braun (Head of this regional office) has been well aware of these problems in the region of West Asia, North Africa, Central Asia, India and China for many years and the need to both train scientists and form strong cohesive networks to enable transfer of technical knowledge, breeding material and form research collaborations. This course was focussed on those soil borne pathogens of cereals with special emphasis on wheat. These pathogens are implicated in causing losses to cereals particularly in marginal environments under either rain-fed agriculture or limited irrigation practices. Australia is a leading country in research on these problems and hence three key teaching staff were bought to Turkey from Australia to teach the course. Dr Albert Rivora (Australian Cereal Root Pathologist and Coordinator of the South Australian ATSE Crawford Fund) was a key initiator for this course to occur in the region. The regional experiences and expertise of both Turkish and French staff offered a complementary set of information and exchange for the participants and also the teaching staff.

  • Screening for resistance to Heterodera filipjevi (Madzhidov) Stelter (Tylenchida: Heteroderidae) and Pratylenchus thornei (Sher & Allen) (Tylenchida: Pratylenchidae) sister lines of spring wheat
    (Entomological Society Turkey, Ege University, 2012) Toktay, H.; Yavuzaslanoglu, E.; Imren, M.; Nicol, J.M.; Elekcioglu, I.H.; Dababat, A.A.
    Breeding for resistance to the cereal cyst nematodes (CCN) Heterodera filipjevi (Madzhidov,) Stelter, and H. avenae (Wollenweber) and to the root lesion nematode (RLN) Pratylenchus thornei (Sher & Allen) is presently being undertaken by breeding programs at research institutions in Turkey. This study was carried out to screen for nematode resistance in an advanced spring bread wheat breeding population, 42 lines (F9) developed at CIMMYT in Mexico, by crossing resistant parent the Middle- Eastern landrace AUS4930 7.2 and susceptible parent, the widely adapted, high yielding CIMMYT line, Pastor. The results demonstrate that 31 lines are resistant to P. thornei and 5 lines are resistant to H. filipjevi. Only 4 of these lines (2, 7, 23 and 41) are resistant to both nematodes. Lines 2, 7 and 41 also contain the known resistance gene, Cre1. Although some lines carry the Cre1 gene, they are susceptible to either both or one of these nematodes. There is no association among H. filipjevi, P. thornei and Cre1 resistance due to differences in the resistance region in the plant genome.
