Stem rust, caused by Puccinia graminis f. sp. tritici, is a devastating disease of wheat. The emergence of race TTKSK (Ug99) and new variants in Africa threatens wheat production worldwide. The best method of controlling stem rust is to deploy effective resistance genes in wheat cultivars. Few stem rust resistance (Sr) genes derived from the primary gene(More)
Drought stress is one of the leading constraints to wheat (Triticum aestivum L.) production globally. Breeding for drought tolerance using novel genetic resources is an important mitigation strategy. This study aimed to determine the level of drought tolerance among diverse bread wheat genotypes using agronomic traits and proline analyses and to establish(More)
Wheat (Triticum aestivum L.) flour functionality during the dough development and baking processes is an important quality attribute considered by the baking industry. A flour with high water absorption during mixing means more water and less flour is needed, compared to a flour with less water absorption. The objective of this study was to identify(More)
We combined the recently developed genotyping by sequencing (GBS) method with joint mapping (also known as nested association mapping) to dissect and understand the genetic architecture controlling stem rust resistance in wheat (Triticum aestivum). Ten stem rust resistant wheat varieties were crossed to the susceptible line LMPG-6 to generate F6 recombinant(More)
This study determined the population structure and genome-wide marker-trait association of agronomic traits of wheat for drought-tolerance breeding. Ninety-three diverse bread wheat genotypes were genotyped using the Diversity Arrays Technology sequencing (DArTseq) protocol. The number of days-to-heading (DTH), number of days-to-maturity (DTM), plant height(More)
Development of high yielding wheat (Triticum aestivum L.) varieties with acceptable end-use quality is a major focus in breeding programs worldwide. Variations in molecular weight (Mw) distribution of endosperm proteins are known to influence end-use quality traits. This paper reports the relationship of the size-exclusion high performance liquid(More)
