Abstract	The inheritance of resistance of the CIMMYT-derived bread wheat line, CIM25, against the most virulent race of leaf rust (Puccinia triticina, syn. P. recondita f.sp. tritici), 77-5, was studied. The low terminal disease severity of this line in field tests was ascribed to two dominant genes. One of these genes was identified as a hypersensitive seedling resistance gene, which remained effective at the adult plant stage. The second gene is the adult plant resistance gene, Lr34, which confers durable resistance to leaf rust. As resistance against race 77-5 is less frequent in bread wheat, the gene for seedling resistance in line CIM25 may find application in wheat breeding programmes
