Inheritance of resistance to wheat leaf rust incited by Puccinia recondita f. sp. tritici was investigated in Waldron, a hard red spring wheat. Waldron is highly resistant to leaf rust in the field and to numerous cultures representing a wide range of virulence in greenhouse tests. Little Club was used as the susceptible parent in reciprocal crosses to Waldron. Genetic analysis revealed that two genes, one dominant and one recessive, in Waldron, conditioned resistance to culture 70-1, a widely avirulent culture of P. recondita. The two genes have been assigned the temporary symbols LrW-1 and LrW-2.
