The widely grown hard red winter wheat cultivar Duster released in 2006 has remained highly resistant to leaf rust caused by Puccinia triticina in the southern Great Plains of the United States. In contrast, many of the winter wheat cultivars in this region are susceptible to leaf rust. The goal of this study was to identify the number and chromosome location of leaf rust resistance genes in a line of Thatcher*2/Duster wheat that was selected for adult plant leaf rust resistance. The Thatcher*2/Duster line was crossed with Thatcher (Tc) and a recombinant line inbred line (RIL) population was advanced to the F6 generation by single-seed descent. The parents and RIL population were phenotyped for leaf rust resistance in three field plot tests and in an adult plant greenhouse test. Single-nucleotide polymorphism (SNP) markers derived from the Illumina Infinium iSelect 90K wheat SNP array, kompetitive allele-specific polymerase chain reaction assays on chromosome 3BL, and a sequence tagged site (STS) marker on chromosome 1BL were used to construct a genetic map of the RIL population. The STS marker csLV46G22 that is linked with resistance gene Lr46 on chromosome 1BL, and SNP marker IWB10344 that is linked with Lr77 on chromosome 3BL, were significantly associated with lower leaf rust severity. Duster has at least three adult plant resistance genes for leaf rust resistance because it was previously determined to also have the adult plant resistance gene Lr34. Duster is a valuable source of durable leaf rust resistance for hard red winter wheat improvement in the Great Plains region.

Leaf rust, caused by the fungus Puccinia triticina, is an important disease of soft red winter wheat cultivars that are grown in the southern and eastern United States. The objectives of this study were to identify the leaf rust resistance genes in two soft red winter wheat cultivars, Coker 9663 and Pioneer 26R61, that have been widely grown and were initially highly resistant to leaf rust. Both cultivars were crossed with the leaf-rust-susceptible spring wheat cv. Thatcher and the F1 plants were crossed to Thatcher to obtain backcross (BC1) F2 families. In seedlings, the Thatcher/Coker 9663 BC1F2 families segregated for three independent seedling resistance genes when tested with different leaf rust isolates. The leaf rust infection types of selected BC1F3 lines, when tested with different leaf rust isolates, indicated that seedling resistance genes Lr9, Lr10, and Lr14a were present. In field plot tests, BC1F4 lines that were seedling susceptible had some adult plant resistance to leaf rust. Seedlings of the Thatcher/Pioneer 26R61 BC1F2 families segregated for two independent resistance genes. Infection types of selected BC1F3 lines indicated the presence of Lr14b and Lr26. The adult plant gene Lr13 was determined to be present in selected BC1F4 lines that were tested with different leaf rust isolates in greenhouse tests.

Fowler, D. B. 2012. Moats hard red winter wheat. Can. J. Plant Sci. 92: 191–193. Moats is a hard red winter wheat (Triticum aestivum L.) that is eligible for grades of the Canada Western Red Winter (CWRW) wheat class. It has excellent stem and leaf rust resistance and higher grain yield and protein concentration than the Central Winter Wheat Cooperative Registration Trial CWRW grain quality check cultivar, CDC Buteo. Its grain yield is similar to the high-yielding Registration Trial check cultivar, CDC Falcon, and lower than Accipiter, which is a more recent high-yielding winter wheat cultivar released in the Canada Western General Purpose wheat class. A suitable combination of grain quality, rust resistance and yield make Moats widely adapted in the winter wheat production area of western Canada.
