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 کاملGenetic analysis and molecular mapping of wheat genes conferring resistance to the wheat stripe rust and barley stripe rust pathogens.
ABSTRACT Stripe rust is one of the most important diseases of wheat and barley worldwide. On wheat it is caused by Puccinia striiformis f. sp. tritici and on barley by P. striiformis f. sp. hordei Most wheat genotypes are resistant to P. striiformis f. sp. hordei and most barley genotypes are resistant to P. striiformis f. sp. tritici. To determine the genetics of resistance in wheat to P. stri...
متن کاملTargeted introgression of a wheat stem rust resistance gene by DNA marker-assisted chromosome engineering.
Chromosome engineering is a useful strategy for transfer of alien genes from wild relatives into modern crops. However, this strategy has not been extensively used for alien gene introgression in most crops due to low efficiency of conventional cytogenetic techniques. Here, we report an improved scheme of chromosome engineering for efficient elimination of a large amount of goatgrass (Aegilops ...
متن کاملMorphological Evaluation and Marker Assisted for Tillering of Wheat
The present research was performed for studying morphological variation and investigating the presence of relationship between molecular markers related tillering in some genotypes of bread wheat under the field farm and laboratory conditions. In the field experiment, three seed densities including 150, 300 and 450 seed per square meter as the main plot factor and also 10 genotypes including th...
