Abstract MAGIC populations represent one of a new generation crop genetic mapping resources combining high recombination and diversity. We describe the creation validation an eight-parent population consisting 1091 F7 lines winter-sown wheat (Triticum aestivum L.). Analyses based on genotypes from 90,000-single nucleotide polymorphism (SNP) array find to be well-suited as platform for fine-mapping quantitative trait loci (QTL) gene isolation. Patterns linkage disequilibrium (LD) show highly...
Genomic selection has recently become an established part of breeding strategies in cereals. However, a limitation linear genomic prediction models for complex traits such as yield is that these are unable to accommodate Genotype by Environment effects, which commonly observed over trials on multiple locations. In this study, we investigated how environmental variation can be captured the collection large number phenomic markers using high-throughput field phenotyping and whether it increase...
Abstract The necrotrophic fungus Parastagonospora nodorum is an important pathogen of one the world’s most economically cereal crops, wheat (Triticum aestivum L.). P. produces protein effectors that mediate host cell death, providing nutrients for continuation infection process. recent discovery has revolutionized disease resistance breeding diseases in crop species, allowing often complex genetic mechanisms to be broken down into constituent parts. To date, three have been identified...
<title>Abstract</title> We assembled a European bread wheat (Triticum aestivum L.) association mapping panel (n=480) genotyped using 90,000 single nucleotide polymorphism array, with the aim of identifying genetic loci controlling resistance to four fungal diseases: yellow (stripe) rust (YR), brown (leaf) (BR), Septoria tritici blotch (ST) and powdery mildew (PM). Simulations showed our have good power detect loci, >50% probability as little 5% variance when heritability was 0.6 or more....
Abstract In wheat, semidwarfism resulting from reduced height ( Rht )‐ B1b and Rht‐D1b was integral to the ‘green revolution’. The principal donors of these alleles are ‘ N orin 10’, S eu eun 27’ uwon 92’ that, according historical records, inherited J apanese landrace D aruma’. objective this study examine origins R ht‐ B 1b by growing multiple seed bank sources cultivars comprising pedigrees donor lines scoring ht‐1 genotype plant height. This revealed that 10’ contained , but source did...
Abstract Flowering time synchronizes reproductive development with favorable environmental conditions to optimize yield. Improved understanding of the genetic control flowering will help varietal adaptation future agricultural systems under climate change. Here, we investigate basis in winter wheat ( Triticum aestivum L.) using an eight-founder multi-parent advanced generation intercross (MAGIC) population. data was collected from field trials across six growing seasons United Kingdom,...
