Wheat leaf rust, caused by Puccinia triticina (Pt), is a globally prevalent fungal disease that causes significant economic loss. Cultivar resistance remains a cornerstone of the management of this pathogen. This study evaluated 86 Indian wheat (Triticum aestivum L.) genotypes to characterize leaf rust resistance (Lr) genes, assess adult plant resistance (APR) under field conditions, and validate resistance using molecular marker analysis. Seedling resistance tests against 14 Pt pathotypes identified nine key Lr genes (Lr1,
