Molecular marker analysis of adult plant resistance to powdery mildew in common wheat
… L.) worldwide. The use of cultivars with resistance to powdery mildew is an efficient, economical and environmentally safe way to control powdery mildew. Race-specific resistance has been extensively used in breeding programs; however, it is ephemeral. Adult plant resistance (APR) to …

Validation of Loci Conferring Adult Plant Resistance to Powdery Mildew in Wheat Cultivar Massey and Identification of Diagnostic Molecular Markers
… of wheat (Triticum aestivum L.). Race-specific resistance is easily identified in the field due to its qualitative phenotype and it is easy to incorporate because it is inherited as a single gene. Unfortunately, this type of resistance is easily overcome by the pathogen. Traits associated with …

Validation, Saturation, and Marker-Assisted Selection of Quantitative Trait Loci Conferring Adult Plant Resistance to Powdery Mildew in an Elite Wheat Breeding Population
… have shifted to breeding for more durable resistance, such as "adult plant resistance" (APR). Molecular markers and quantitative trait loci (QTL) associated with APR to powdery mildew must first be validated and QTL effects evaluated in different genetic backgrounds and breeding populations …

Dissecting the Multifaceted Relationship Between Maize and Cochliobolus carbonum race 1
… virulence. The maize Hm1 gene confers complete resistance to CCR1 at all stages of development by encoding for an NADPH-dependent reductase that inactivates HC-toxin. Hm1A, Hm1-SM1, and Hm1-SM2 are alleles of Hm1 that exhibit an adult plant resistance (APR) phenotype, being fairly susceptible …

Effects of the Lr34 and Lr46 rust-resistance genes on other diseases of wheat
Lr34 and Lr46 are adult plant resistance genes providing durable resistance to biotrophic diseases of wheat like rusts and powdery mildew. In seedlings, these genes increased susceptibility to Septoria tritici blotch (STB), caused by Zymoseptoria tritici, in near-isogenic lines (NILs) of spring …

A genome-wide association study of resistance to the yellow rust pathogen (Puccinia striiformis f. sp. tritici) in elite UK wheat germplasm
… 2013 A genome wide association study of resistance to the yellow rust pathogen (Puccinia striiformis f. sp. tritici) in elite UK wheat germplasm Identification of marker-trait associations (MTA) in germplasm relevant to breeding program via association mapping (AM) can be an effective way …

Identification and Mapping of Adult Plant Stripe Rust Resistance in Soft Red Winter Wheat
… objectives of this study are to identify and map adult plant stripe rust resistance quantitative trait loci (QTL) in soft red winter (SRW) wheat that are effective against race PST-100, which is the predominant race of the pathogen in the eastern U.S. Adult plant resistance (APR) was characterized …

Genetically dissect disease interactions between Parastagonospora nodorum and wheat (Triticum aestivum L.)
… could help increase P. nodorum disease resistance. The research presented here falls into three main areas: 1. Genetic mapping of SnTox3 sensitivity: the major SnTox3 sensitivity locus Snn3-B1 was fine-mapped using an association mapping panel, the Avalon x Cadenza population and a MAGIC …

Identification and Mapping of Resistance to Puccinia striiformis and Puccinia triticina in Soft Red Winter Wheat
Disease resistance is critical in soft red winter wheat (Triticum aestivum L.) cultivars. Leaf rust caused by Puccinia triticina Eriks and stripe rust caused by Puccinia striiformis Westend. f.sp. tritici Eriks. are destructive pathogens of wheat. From 2014 to 2015 phenotypic data was collected at …
