Genotyping by Sequencing and Rust Resistance of Azerbaijani Durum Wheat Germplasm (original) (raw)
Genotyping-by-sequencing (GBS) is a genetic screening method for discovering and genotyping novel single nucleotide polymorphisms (SNPs) in crop genomes and populations. In the current research a phenotypic and genotypic assessment of 76 durum wheat (Triticum durum Desf.) accessions of Azerbaijan origin was made using six phenotypic traits and GBS technology. After screening for leaf and stem rust resistance at the seedling stage, 16 genotypes displayed resistance to leaf rust and 14 to stem rust. Some relationships were found between resistance to leaf rust and phenotypic traits of botanical varieties. The highest Pearson’s correlation (r=0.53; p < 0.001) was noted between awn color and pubescence. The durum wheat genotypes fell into four main groups in the clustered heat map; grouping according to botanical variety. A total of 748 SNP markers were obtained for the collection. The average polymorphic information content and genetic diversity index for the entire collection were ...
