Projects

Research Overview

We are mobilizing genetic diversity to enhance wheat yields and meet food security needs. Without genetic diversity, breeders will be unable to make the progress necessary to feed future generations. It is the key to delivering varieties to farmers with the “genetic grit” to fight devastating disease, destructive pests, and severe climates. The WGRC IUCRC […]

Genebank Genetics

Genomic Characterization of the WGRC Collection: Analysis of A-genome diploids and Aegilops species Project Summary: The genebank of the Wheat Genetics Resource Center holds over 2,200 accessions of wild wheat relatives and 12,000 genetic stocks including introgression lines and mapping populations.  This vast resource can provide valuable raw material for the future of wheat improvement, […]

Phenotype Core

Phenotypic Characterization of Wild Wheat Core Sets Project Summary: Core collections of Aegilops tauschii (40 accessions) and tetraploid wheat (92 accessions) were phenotyped for important traits in greenhouse, field and rainout shelter experiments.  These core sets had greenhouse data collected during the years of 2015-2018 for resistance to leaf rust, stripe rust, tan spot, Septoria nodorum Hessian […]

Emmer Quality Evaluation

Quality Evaluation of Wild Emmer Introgressions Project Summary: This is a 2-year project to evaluate quality traits in populations of wheat derived from backcrosses of bread wheat to wild emmer at a preliminary stage of germplasm development.  Optional extensions of this project to develop genomic information, DH lines, and yield trial plots that would provide […]

Tauschii Glutenins

Direct Assessment of Novel Glutenin Alleles in Aegilops tauschii Project Summary For milling and baking quality of raised breads there are important genetic determinants including strong effects from the glutenin genes.  Being situated on different genomes, the various alleles of high-molecular weight and low-molecular weight glutenins represent inherited diversity from different wheat ancestors.  Though the […]

Recombination Promoters

Novel Genetics Stocks for Chromosome-wide Enhancement of Genetic Recombination Project Summary: The gene pool of cultivated bread wheat is very narrow relative to its wild relatives and related species.  This tertiary genepool represents a large reservoir of agronomically important genes that can be used in wheat improvement.  Gene transfer from distantly related species of the […]

Resistance Mapping

Genetic Analyses of Rust Resistance in Aegilops tauschii Project Summary: Diverse genetic components of disease resistance in wheat are critical to ensure long-term food security. Aegilops tauschii was documented to preserve many disease resistance genes that are not present in bread wheat. Hundreds of Aegilops tauschii accessions have been collected and characterized for their resistance […]

Breeding Germplasm

Field-based Germplasm Development from Wild Species Project Summary: This is a continuation (years 3 – 5) of a project with the objectives of: 1) establishing a prebreeding program that produces enhanced germplasm derived from the wild wheat collections that is suitable for use in commercial wheat breeding programs and 2) producing introgession libraries that immortalize […]

Sawfly

Screening and Characterization of Resistance for Sawfly Project Summary: Wheat stem sawfly (WSS, Cephus cinctus) has long been considered the most important pest of wheat in the northern Great Plains of North America. In recent years, damage from WSS has expanded to areas of Nebraska, Wyoming, and Colorado that had not previously been affected. Adult […]

Chemical Drivers

Identification of Chemical Drivers of Liking in Wheat Project Summary: The overall goal of this proposal is to identify molecular markers that enable genomic breeding programs to enhance flavor traits of wheat germ plasm. To achieve this goal the current proposal is focused on the identification of volatile and non-volatile flavor compounds or modulators in […]
