Identification of Candidate Genes and Genomic Regions Associated with Adult Plant Resistance to Stripe Rust in Spring Wheat

Wheat stripe rust (caused by Puccinia striiformis f. sp. tritici) is a major disease that damages wheat plants and affects yield all over the world. In recent years, became problem in Egypt. New races appeared caused breakdowns resistant genotypes. To improve resistance Egyptian genotypes, new sources of are urgently needed. research, set 95 genotypes collected from 19 countries, including Egypt, were evaluated for their against race(s) under field conditions two growing seasons 2018/2019 2019/2020. A high genetic variation was found among tested Single marker analysis conducted using subset 71 424 diversity array technology (DArT) markers, well distributed across genome. Out 13 stable markers identified significantly associated with both years (p-value ? 0.05). By sequence DArT chromosomal position significant detected, nearby gene models identified. Two on chromosomes 5A 5B to be located within functionally annotated plants. These could used marker-assisted selection conditions. German carrying targeted allele
