Genetic and genomic studies of important traits of wheat in the US Great Plains. Traits include drought and heat tolerance, resistance to diseases (leaf, stem and stripe rust, wheat streak mosaic virus), and arthropods (greenbug, Russian wheat aphid, hessian fly, and wheat curl mite) as well as good end-use quality. Both traditional and molecular breeding techniques are used to develop germplasm lines with one or more target traits. Genomic techniques include gene/QTL mapping, molecular marker identification, validation and utilization, high throughput KASP SNP screening, and gene cloning. Gene functional analysis will be used to understand and improve those target traits.
1. Genetic mapping and genomics studies of QTL for yield, yield components under dry and irrigated conditions, and other traits in adapted cultivars; Study drought tolerance through transcriptomics of water stressed wheat plants.
2. Developing germplasm lines with multiple favorable alleles with drought tolerance, insect and wheat streak mosaic virus resistances using high throughput and diagnostic KASP SNP.
3. Cloning of greenbug resistance gene, identification of candidate genes through molecular techniques.
