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 (PHT), spike length (SPL), number of ...

Genomic regions responsible for accumulation of grain iron concentration (Fe), grain zinc concentration (Zn), grain protein content (PC) and thousand kernel weight (TKW) were investigated in 286 recombinant inbred lines (RILs) derived from a cross between an old Indian wheat variety WH542 and a synthetic derivative (Triticum dicoccon PI94624/Aegilops squarrosa [409]//BCN). RILs were grown in si...

Different physiological traits have been proposed as key traits associated with yield potential as well as performance under water stress. The aim of this paper is to examine the genotypic variability of leaf chlorophyll, stem water-soluble carbohydrate content and carbon isotope discrimination (Δ(13)C), and their relationship with grain yield (GY) and other agronomical traits, under contrastin...

In this study, eight promising advanced bread wheat genotypes derived from breeding programs and Ceyhan-99, Sagittario, Masaccio, Seri-82 commercial cultivars were used as materials. The experiments carried out in 2018-2019 2019-2020 cropping years a randomized complete block design with four replications. the some agronomic quality traits investigated. Bread varied significantly for all invest...

Genotype (G), environment (E), management (M), and their interactions determine grain yield, biochemical composition, quality of wheat. However, we are not aware studies evaluating whether intensive can simultaneously reduce yield gaps improve wheat milling baking attributes, which were our main objectives. A factorial experiment five genotypes × four intensities (farmer practice, high-input, h...

Selection of parents based on their combining ability is an effective approach in hybrid breeding. In this study, eight maintainer lines and nine restorer lines were used to obtain 72 crosses for analyzing the general combining ability (GCA) and special combining ability (SCA) for seven agronomic and yield characters including plant height (PH), spike length excluding awns (SL), inter-node leng...

Understanding genetic architectures of yield and yield-related traits wheat (Triticum aestivum L.) grown under dryland or irrigated conditions is pivotal for developing modern high-yielding germplasm cultivars. The objectives this study were to detect quantitative trait loci (QTL) linked components using a mapping population derived from ‘TAM 113’/‘Gallagher’, including 191 recombinant inbred l...

Bread wheat landraces are considered among important gene sources for quality breeding programs. This study aims to compare thousand kernel weight crude protein ratio, dry gluten grain hardness and zeleny sedimentation results of 20 bread lines selected from 5 registered cultivars in order determine future candidates Field experiments were conducted the consequent 2012-2013 2013-2014 growing se...

Seed yield of any hybrid maize (Zea mays L.) variety emerges depending on parental characteristics inbred lines used. Even though, traits each line are recorded there is no clear information about that contribute to and associations among those characters. The present study was conducted using 14 at Bako National Maize Research Centre in 2018/2019 based Randomized complete block design w...
