Molecular 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...
متن کاملCharacterization of Stripe Rust Resistance Genes in the Wheat Cultivar Chuanmai45.
The objective of this research was to characterize the high level of resistance to stripe that has been observed in the released wheat cultivar, Chuanmai45. A combination of classic genetic analysis, molecular and cytogenetic methods were used to characterize resistance in an F₂ population derived from Chuanmai45 and the susceptible Chuanmai42. Inheritance of resistance was shown to be conferre...
متن کاملCytological identification of an Aegilops variabilis chromosome carrying stripe rust resistance in wheat
Aegilops variabilis (UUSvSv), an important sources for wheat improvement, originated from chromosome doubling of a natural hybrid between Ae. umbellulata (UU) with Ae. longissima (SlSl). The Ae. variabilis karyotype was poorly characterized by fluorescent in situ hybridization (FISH). The FISH probe combination of pSc119.2, pTa71 and pTa-713 identified each of the 14 pairs of Ae. variabilis chr...
متن کاملAllelic analysis of stripe rust resistance genes on wheat chromosome 2BS.
Stripe rust, caused by Puccinia striiormis Westend f. sp. tritici, is one of the most important foliar diseases of wheat (Triticum aestivum L.) worldwide. Stripe rust resistance genes Yr27, Yr31, YrSp, YrV23, and YrCN19 on chromosome 2BS confer resistance to some or all Chinese P. striiormis f. sp. tritici races CYR31, CYR32, SY11-4, and SY11-14 in the greenhouse. To screen microsatellite (SSR)...
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...
