Abstract Background The nematode phylum includes many species key to soil food webs with trophic behaviours extending from feeding on microbes macrofauna and plant roots. Among these, the parasitic cyst nematodes retain their eggs in protective cysts prolonging survival under harsh conditions. These nematodes, including those genus Heterodera , cause significant economic losses agricultural systems. Understanding of diversity ecology has expanded through application genomic research,...

To identify loci linked to nematode resistance genes, a total of 126 CIMMYT advanced spring wheat lines adapted semi-arid conditions were screened for Heterodera avenae, Pratylenchus neglectus, and P. thornei, which 107 genotyped with 1,310 DArT.Association DArT markers response was analyzed using the general linear model.Results showed that 11 associated H. avenae (pathotype Ha21), 25 9 significant identified be thornei.In this work we confirmed chromosome 4A (~90-105 cM) can source thornei...

Cereal cyst nematodes (CCNs) are plant parasites that significantly limit global cereal production. The most frequently reported pathogenic species Heterodera avenae, H. filipjevi, and latipons. One of the cost-effective, environmentally friendly, easily adopted control measures is use genetic host resistance, which maintains nematode populations below economic damage threshold level. Many effective sources resistance to CCNs have been identified in cereals; however, their effectiveness...

Plant parasitic nematodes are a major biotic cause of wheat-yield loss in temperate wheat-growing regions. A strategy to develop resistance root-lesion (RLNs) wheat is assess and then exploit their natural genetic variation. This study examines RLN (Pratylenchus thornei) 1 Middle Eastern landrace (AUS4930 7.2) synthetic hexaploid wheat, CROC_1/AE.SQUARROSA (224)//OPATA (CROC), using F 2 9 populations generated by crossing AUS4930 7.2 CROC with the susceptible cultivar Pastor, inoculating...

Root knot nematodes (<italic>Meloidogyne</italic> spp.) cause immense yield losses in crops throughout the world. Use of resistant germplasms plants limits root nematode damages. In this study, 87 common bean (<italic>Phaseoulus vulgaris</italic> L.) genotypes were screened against nematode, <italic>Meloidogyne incognita</italic> to determine resistance response under growth chamber conditions Turkey. <italic>P. evaluated based on index (RI); galling...

Wheat (Triticum spp.) is highly susceptible to the root lesion nematode, Pratylenchus thornei, which causes excessive amounts of crop losses each year. In this research, we investigated cumulative effect biocontrol agent Purpureocillium lilacinum (syn: Paecilomyces lilacinus) against P. thornei. Three doses (106, 107 and 108 conidia cultures mL-1) with one dose 400 thornei individuals (adults juveniles) mL-1 were applied in 100 cm3 soil under greenhouse conditions. The number nematodes...

Turkey is ranked among top ten wheat producing countries in the world. Cereal cyst nematodes are considered one of most damaging plant parasitic on worldwide. Up to date, effective method controlling this group use crop rotation and resistant varieties. The successful development disease-resistant plants contingent knowledge pathotypes causal agent. In study, three populations Heterodera filipjevi (Madzhidov, 1981) Stelter were collected from different locations (Afsin, Elbistan Yozgat)...
