Leaf rust, caused by Puccinia triticina Pt) is among the most devastating diseases posing a significant threat to wheat production globally. Host resistance is the most effective management strategy to control rust diseases. The wheat genepool contains a large set of resistance genes, with currently having more than 150 race specific all stage resistance (ASR) genes identified,
and many are effectively deployed in wheat cultivars. The race specific genes provide resistance at the seedling stage. In contrast, non race specific, adult plant resistance (APR) is often partial resistance at the adult plant stage and more durable due to non specificity to the pathogen races. Identification of resistance loci conferring adult plant resistance against leaf rust will help in
developing durable leaf rust resistant cultivars. Therefore, exploring new sources of resistance is important for proper utilization of resistant sources.
