Abstract
The Canadian wheat (Triticum aestivum L.) cultivar Pasqua has good resistance to leaf rust (Puccinia recondita Rob. ex Desm.) and some sprouting resistance. Backcross F2 families were used to study the inheritance of leaf rust resistance in Pasqua. Based on the leaf rust resistance genotypes of its parents, Pasqua could have genes Lr11, Lr13, Lr14b, Lr16, Lr22, and Lr30. Of these, it was found to have Lr11, Lr13, Lr14b, and Lr30. As well, it has Lr34, which must have come from the cultivar Terenzio during the development of a Neepawa backcross line with Lr30. Key words: Triticum aestivum, wheat, leaf rust resistanceKeywords
