Genetic diversity and genome-wide association study of yellow rust resistance in elite spring bread wheat genotypes in Ethiopia.

ABSTRACT:

Background

Yellow rust, caused by Puccinia striiformis f. sp. Tritici (Pst), is one of the most destructive wheat diseases in the world. It can cause, yield losses of up to 100% during severe outbreaks. The use of resistant wheat varieties is the most effective and environmentally sustainable approach to control yellow rust. This study aimed to assess genetic diversity and identify molecular markers associated with stripe rust resistance. A total of 186 elite bread wheat lines from the International Center for Agricultural Research in the Dry Areas (ICARDA) were investigated for genetic diversity and genome-wide association studies (GWAS) using 17,920 SNP markers. The genotypes were phenotyped for yellow rust resistant under natural infestation condition at five environments in Eth
