Abstract
The genetic basis of leaf rust resistance of cultivar Dove developed at Centro International de Mejoramiento de Maizy Trigo (CIMMYT) was studied against Indian leaf rust (Puccinia triticina, syn. P. recondita f.sp. tritici) race 77-5. Multirace tests on seedlings and adult plants of cultivar Dove and the reference lines for the known adult plant leaf rust resistance genes against races 12-2, 77-1, 77-2 and 77-5 suggested that cultivar Dove carries as yet undescribed adult plant resistance genes. On the basis of genetic studies, the resistance at adult plant stage against race 77-5, the most virulent race from Indian subcontinent, was ascribed to two genes. One of these two genes is the non-hypersensitive adult plant resistance gene Lr34. The second gene is a new and as yet undescribed recessive hypersensitive adult plant resistance gene
