The gene for adult-plant resistance to race 9 of leaf rust (Puccinia recondita Rob. ex. Desm.) in the common wheat cultivar Thatcher (Triticum aestivum L.) was allelic to Lr22a, a gene for adult-plant leaf rust resistance previously transferred to hexaploid wheat from Aegilops squarrosa L. This gene, designated Lr22b, was linked with Tg, a gene for tenacious glumes, and W21, an inhibitor of waxy foliage, both known to be on chromosome arm 2Dα and linked with Lr22a.

Red Winter Wheat

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.

Red Winter Wheat

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.
