Evaluation Of Kentucky Grown Soft Red Winter Wheat With Sensory Evaluation For Bread-Making Capabilities And Quality, Asa Conkwright Iii
Evaluation Of Kentucky Grown Soft Red Winter Wheat With Sensory Evaluation For Bread-Making Capabilities And Quality, Asa Conkwright Iii
Theses and Dissertations--Nutrition and Food Systems
Soft red winter (SRW) wheat is a type of wheat that is best suited to grow in Kentucky. However, due to its low protein content, it is an undesirable flour for bread and is usually used for cakes, cookies, crackers, and pastries. This is problematic because this limits the ability for commercial bakers to have a local source of flour, forcing them to purchase from sources outside the state. In doing so, bakers are sacrificing freshness and quality. It also removes the opportunity to keep profits in Kentucky, contributing to the state’s economy. The purpose of this study was to …
Effect Of Allelic Variation In Rht Loci On Plant Height And Grain Yield Of Soft Red Winter Wheat (Triticum Aestivum L.), Habib Hayat
Graduate Theses and Dissertations
Plant height in wheat (Triticum aestivum L.) is controlled in large part by two major Rht genes, Rht-B1 and Rht-D1, which pleiotropically impact lodging and grain yield. Prior to the Green Revolution, wheat varieties contained only ‘wild-type’ Rht alleles (Rht-B1a and Rht-D1a) and were tall and prone to lodging. Introgression of a semi-dominant mutation at either of these two loci (Rht-B1b or Rht-D1b) results in a semi-dwarf phenotype and reduced plant height. When combined (Rht-B1b and Rht-D1b) an extremely short double-dwarf phenotype is observed. The objective of this study was to determine the impact of allelic variation in Rht-B1 and …
Association Mapping And Genomic Selection For Yield And Agronomic Traits In Soft Winter Wheat, Dennis Bulusan Lozada
Association Mapping And Genomic Selection For Yield And Agronomic Traits In Soft Winter Wheat, Dennis Bulusan Lozada
Graduate Theses and Dissertations
Tools such as genome-wide association study (GWAS) and genomic selection (GS) have expedited the development of crops with improved genetic potential. While GWAS aims to identify significant markers associated with a trait of interest, the goal of GS is to utilize all marker effects to predict the performance of new breeding lines prior to testing. A GWAS for grain yield (GY), yield components, and agronomic traits was conducted using a diverse panel of 239 soft winter wheat (SWW) lines evaluated in eight site-years in Arkansas and Oklahoma. Broad sense heritability of GY (H2=0.48) was moderate compared to other traits including …
