Epistasis for agronomic traits in elite maize hybrids
<p>Certain maize (Zea mays L.) inbred lines are more successful than others in forming elite hybrids. This study was conducted to determine whether epistatic interactions play a significant role in hybrid performance, whether an epistatic or non-epistatic model satisfactorily explains the variation …

Influence of lignin in barley straw on agronomic traits and biofuel applications
… the same population along with a number of other agronomically important traits, such as thousand-grain weight, biomass, mechanical stem properties and height. The data provided by these measurements allowed correlations between traits to be identified and their strength gauged. Genome wide …

Development of tools to study the association of transposons to agronomic traits
… to influence alleles associated with important agronomic traits, such as apical dominance in maize and seed number in rice. Crops may harbor more TE-mediated genetic regulations than expected in view of multifunctional TEs in genomes. However, tools that accurately annotate TEs and clarify their …

ASSOCIATION MAPPING OF GENE REGIONS FOR DROUGHT TOLERANCE AND AGRONOMIC TRAITS IN SORGHUM
… because of the complex nature of these traits. To make this process more tractable, studies were conducted to investigate the genetic architecture of these traits by employing a novel multi-parent advanced generation intercross (MAGIC) population. The population was formed from 19 …

Breeding strategies for wine grapes: From genetic analysis of agronomic traits to wine sensory evaluation
… were the analysis of the genetic basis of agronomic traits in wine grape, the assessment of the influence of berry size in the oenological composition of segregating progenies and clones; and the sensory evaluation of wines derived from Graciano × Tempranillo selections. Two segregating …

Identification of molecular markers and association mapping of selected loci associated with agronomic traits in rice
… select molecular markers associated with complex traits in US rice germplasm. Markers for percent head rice, percent total rice, and grain yield were identified with high levels of correct classification that mapped within or near traditional Quantitative Trait Loci (QTL). Mixed model-regression …

Linkage fine-mapping, GWAS and QTLs affecting morpho-agronomic traits of a common bean RIL population
… map and detect QTLs related to seven morpho-agronomic traits using these two methodologies. Another objective was to know the biological function of these QTLs by their location in relation to candidate genes with biological functions that related to the traits of these QTLs. The population …

Genetic mapping of agronomic traits from the interspecific cross of Oryza sativa (L.) and Oryza glaberrima (Steud.)
… were to detect quantitative trait loci (QTL) for agronomic traits in a hybrid mapping population and compare the non-parametric Discriminant Analysis (DA) procedure with traditional approaches for accuracy and precision. In addition, the effects of population structure on marker-assisted …

Quantifying the Diversity of Agronomic Traits of Cicer Milkvetch (Astragalus cicer L.) Germplasm Collections Using UAV-Based Imagery
… of cicer milkvetch using agro-morphological traits, 2) Differentiate a sub-set of cicer milkvetch populations from June to mid-October using UAV-based multispectral imaging, and 3) Identify UAV-based traits with significant correlations to the forage DMY and growth of cicer milkvetch. Near …

Phenotyping Canola (Brassica napus L.) Agronomic Traits and Estimating Seed Yield Using Unoccupied Aerial Vehicle (UAV)-based Multispectral Imagery
… and multispectral sensors, desirable phenotypic traits and seed yield can be estimated digitally. In this thesis, the main objective was to develop an efficient and non-destructive method to estimate canola flowering number, flowering layer depth, canopy height, and seed yield using UAV-based …

Molecular mapping of quantitative trait loci (QTL) for Fusarium head blight (FHB) resistance and agronomic traits in US hard winter wheat
… germplasms usually have many undesirable agronomic traits. To dissect the relationship between FHB resistance and yield component traits, we developed two recombinant inbred line (RIL) populations for identification of native FHB resistance quantitative trait loci (QTL) in US hard winter …

Genetic variation of heat tolerance and correlation with other agronomic traits in a maize (Zea mays L.) recombinant inbred line population
… and to estimate the heritability of those traits. A total of 179 maize recombinant inbred lines from B76 x B106 were evaluated at Pecos, TX, in 2001, at Texas Tech University (TTU) experimental farm in 2002, and at TAMU Lubbock center in 2001 and 2002. Significant variation in leaf firing, …

Genetic and Environmental Responses of Harvest Index and Other Agronomic Traits in Winter Wheat (Triticum Aestivum L.) and Spring Oats (Avena Sativa L.)
… oats investigated the potential of several agronomic traits, especially harvest index, total dry matter production, and growth rate, for improving grain yield. The effect of four nitrogen fertilizer treatments on harvest index, grain yield, grain protein percentage, grain protein yield, and …

Gene action in the inheritance of agronomic traits in intervarietal diallel crosses and relative importance of gene effects for quantitative characters in Zea mays L
… to determine gene action in the inheritance of agronomic traits in a diallel set of eight inbred lines of sweet corn and all possible Fl hybrids, including parents. Data were analyzed by Jinks and Hayman's diallel analysis for plant and ear height, weight with and without husk, shank and ear …

Genetic marker analysis of three major carbohydrates in soybean seeds
… stachyose are one of the important seed quality traits in soybean. However, little is known about the genetics of these quantitative traits. Recombinant inbred lines (RIL) were developed from the interspecific hybridization between a Glycine max breeding line (V71-370) and a Glycine soja plant …

Genetic analysis of Cannabis flowering traits in differential environments
… necessitated the improvement of inflorescence traits relating to uniformity, quality, and yield under diverse growing conditions. Cannabis agronomic traits exhibit significant phenotypic variation due to both underlying genetic diversity and environmental heterogeneity. This dissertation …

Avoiding trade-off when enhancing Fusarium head blight resistance of barley
… Resistance to FHB is associated with several agronomic traits, particularly height. Taller cultivars are generally more resistant; however increased height is less favourable due to the prospect of lodging, creating a trade-off between disease resistance and agronomic qualities. Disease assays …
