Linkage Maps of Wheat Stripe Rust Resistance Genes Yr5 and Yr15 for Use in Marker-Assisted Selection
Stripe rust (caused by Puccinia striiformis Westend. f. sp. tritici Eriks.) is a serious disease of wheat (Triticum aestivum L.). Resistance genes Yr5 and Yr15 are the only known all-stage resistance genes that defeat all stripe rust races currently found in the United States. Previously mapped markers for these genes, however, show limited polymorphism across diverse genotypes and/or map at a ...
متن کاملMolecular marker mapping of leaf rust resistance gene lr46 and its association with stripe rust resistance gene yr29 in wheat.
ABSTRACT Leaf and stripe rusts, caused by Puccinia triticina and P. striiformis, respectively, are globally important fungal diseases of wheat that cause significant annual yield losses. A gene that confers slow rusting resistance to leaf rust, designated as Lr46, has recently been located on wheat chromosome 1B. The objectives of our study were to establish the precise genomic location of gene...
متن کاملDevelopment of RAPD based markers for wheat rust resistance gene cluster (Lr37-Sr38-Yr17) derived from Triticum ventricosum L
Rust diseases are the major cause of low yield of wheat in Pakistan. Wheat breeders all over the world as well as in Pakistan are deriving rust resistance genes from alien species like Triticum ventricosum and introducing them in common wheat (Triticum aestivum). One such example is the introgression of rust resistance gene cluster Lr37-Sr38-Yr17 derived from T. ventricosum chromosome 2NS into ...
متن کاملMicrosatellite markers for the Triticum timopheevi-derived leaf rust resistance gene Lr18 on wheat 5BL chromosome
Leaf rust, caused by Puccinia triticina, is a common wheat disease worldwide. Developing resistant cultivars through deploying new or pyramiding resistance genes in a suitable line, is the most effective approach to control this disease. However, to stack genes in a genotype, efficient and reliable markers are required. In the present study, F2 plants and their corresponding F3 families from a ...
متن کاملIdentification of QTLs for Rust Resistance in the Peanut Wild Species Arachis magna and the Development of KASP Markers for Marker-Assisted Selection
Rust is a major pathogen of the peanut crop. Development and adoption of rust-resistant cultivars is the most cost efficient and effective way to control the spread of the disease and reduce yield losses. Some cultivated peanut germplasm accessions have a degree of resistance, but the secondary gene pool is a source of much stronger resistance alleles. Wild species, however, have undesirable ag...
