The Effect of Grain Position on Genetic Improvement of Grain Number and Thousand Grain Weight in Winter Wheat in North China
Genetic improvements have significantly contributed to wheat production. Five wheat cultivars-widely grown in north China in the 1950s, 1990s, or 2010s-were grown in field experiments conducted in the 2014-2015 and 2015-2016 growing seasons. This study evaluated the genetic progress in wheat grain yield and its related traits in north China and explored how breeding and selection have influence...
متن کاملGenetic Analysis of Grain Yield and Yield Components in Bread Wheat using Hayman's Diallel Method
Extended Abstract Introduction and Objective: By progeny trial after a diallel crossing, the function of genes and inheritance of quantitative traits can be estimated. This increases the ability to select parental lines, to participate in crosses, and determines the management of generations in the segregating populations. Material and Methods: In order to understand the genetic structure of ...
متن کاملCharacterization of Proteins from Grain of Different Bread and Durum Wheat Genotypes
The classical Osborne wheat protein fractions (albumins, globulins, gliadins, and glutenins), as well as several proteins from each of the four subunits of gliadin using SDS-PAGE analyses, were determined in the grain of five bread (T. aestivum L.) and five durum wheat (T. durum Desf.) genotypes. In addition, content of tryptophan and wet gluten were analyzed. Gliadins and glutenins comprise fr...
متن کاملPulmonary reaction to durum wheat; a constituent of grain dust.
To identify constituents of grain dust responsible for grain handlers' respiratory symptoms, 11 volunteer grain elevator workers underwent inhalation provocation tests with extracts of durum wheat, durum wheat airborne dust, and grain insects and mites. Factors that might influence the host response to the challenge were assessed. Five of the 11 subjects showed a greater than 20 percent decreme...
متن کاملGenetic Dissection of Grain Size and Grain Number Trade-Offs in CIMMYT Wheat Germplasm
Grain weight (GW) and number per unit area of land (GN) are the primary components of grain yield in wheat. In segregating populations both yield components often show a negative correlation among themselves. Here we use a recombinant doubled haploid population of 105 individuals developed from the CIMMYT varieties Weebill and Bacanora to understand the relative contribution of these components...
