Abstract: (77 Views)
Resistance traits are economically important in crops in terms of accessibility to promising resistant germplasms. This study was conducted to evaluate SNP marker-trait association for cereal cyst nematode, CCN, Heterodera filipjevi on/in a large number of natural bread wheat population. Phenotypic data analysed by GLM (Generalized Linear Model) indicated significant differences among the landrace accessions genotypes for resistance to H. filipjevi. The genotyping was performed by 152K SNP chip on 188 accessions. After filtering, 10471 polymorphic SNPs were employed for Genome Wide Association Study, GWAS analysis. Population structure among the wheat genotypes were investigated using 840 well distinct SNP markers. Two sub-populations revealed by structure software. As a result, eleven markers were significant (p-value < 0.001) and associated with resistance to H. filipjevi on chromosomes 2A, 3B, 4A, 4B, 5A, 5B, 5D, and 6B. The linkage disequilibrium analysis for all significantly associated SNPs showed that markers on chromosomes 4A and 4B were in high intra-chromosomal LD, and consequently, the 11 SNPs could be reduced to eight markers. The present study demonstrates valuable sources of resistance in the studied wheat genotypes to a widespread and important species of CCN in some areas of the crescent fertile region. The associated markers could be used in molecular bread wheat breeding programs.
