Characterization of a Wheat Breeders’ Array suitable for high‐throughput SNP genotyping of global accessions of hexaploid bread wheat (Triticum aestivum)
Targeted selection and inbreeding have resulted in a lack of genetic diversity in elite hexaploid bread wheat accessions. Reduced diversity can be a limiting factor in the breeding of high yielding varieties and crucially can mean reduced resilience in the face of changing climate and resource pressures. Recent technological advances have enabled the development of molecular markers for use in ...
متن کاملConversion of array‐based single nucleotide polymorphic markers for use in targeted genotyping by sequencing in hexaploid wheat (Triticum aestivum)
Wheat breeders and academics alike use single nucleotide polymorphisms (SNPs) as molecular markers to characterize regions of interest within the hexaploid wheat genome. A number of SNP-based genotyping platforms are available, and their utility depends upon factors such as the available technologies, number of data points required, budgets and the technical expertise required. Unfortunately, m...
متن کاملHigh‐density genotyping of the A.E. Watkins Collection of hexaploid landraces identifies a large molecular diversity compared to elite bread wheat
The importance of wheat as a food crop makes it a major target for agricultural improvements. As one of the most widely grown cereal grains, together with maize and rice, wheat is the leading provider of calories in the global diet, constituting 29% of global cereal production in 2015. In the last few decades, however, yields have plateaued, suggesting that the green revolution, at least for wh...
متن کاملHigh‐density SNP genotyping array for hexaploid wheat and its secondary and tertiary gene pool
In wheat, a lack of genetic diversity between breeding lines has been recognized as a significant block to future yield increases. Species belonging to bread wheat's secondary and tertiary gene pools harbour a much greater level of genetic variability, and are an important source of genes to broaden its genetic base. Introgression of novel genes from progenitors and related species has been wid...
متن کاملMorphology, Biochemical and Genomic Diversity of Hexaploid Wheat (Triticum aestivum L.) Varieties in Ethiopia: A Prospective Study
Hexaploid Wheat (Triticum aestivum L.) is one of the most important food cereals grown in many areas worldwide. World population is to increase by 2.6 billion in 2050. Ethiopia is one of the world’s nine countries needed to increase food production. Since few studies on genetic diversity & in adequate evaluation of bread wheat varieties; my objective the project is to study genetic diversity of...
