Detection of quantitative trait loci associated with leaf rust resistance in bread wheat.
Leaf rust, caused by Puccinia recondita Rob. ex Desm., is a common disease in wheat. The objective of this study was to develop molecular markers associated with the quantitative trait loci (QTLs) putatively conferring durable leaf rust resistance in Triticum aestivum L. em. Thell. A population of 77 recombinant inbred lines (RILs) developed from 'Parula' (resistant) and 'Siete Cerros' (moderat...
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 کاملRegistration of Five Wheat Isogenic Lines for Leaf Rust and Stripe Rust Resistance Genes
We report here the release of four germplasm lines of hard red spring (HRS) wheat (T. aestivum L.) [Yecora Rojo Yr36– Gpc-B1 (Reg. no. GP-793, PI 638740), Yecora Rojo Lr47 (Reg. no. GP-791, PI 638738), Kern Lr47 (Reg. no. GP-792, PI 638739), and Anza Lr37/Yr17/Sr38 (Reg. no. GP-795, PI 638742)] and one durum wheat (T. turgidum L.) [UC1113 Yr36– Gpc-B1 (Reg. no. GP-794, PI 638741)], isogenic for...
متن کاملMolecular mapping of a stripe rust resistance gene in spring wheat cultivar Zak.
Stripe rust (yellow rust), caused by Puccinia striiformis f. sp. tritici, is one of the most devastating foliar diseases of wheat (Triticum aestivum) worldwide. Growing resistant cultivars is the best approach for control of the disease. Although the stripe rust resistance in spring wheat cv. Zak has been circumvented by a group of races of the pathogen predominant in the United States since 20...
