Available in PDF, EPUB and Kindle. Book excerpt: The development of cultivars with modified seed composition represents an excellent alternative to cope with the world's need for more nutritious food. Understanding the genetic and environmental factors controlling crop seed quality traits is of crucial importance for such an endeavor. The objectives of this study were: a) to evaluate the efficiency of phenotype and marker-assisted selection for low stachyose and low phytate soybean breeding lines, and their yield stability, b) to study the effect of management practices planting date and delayed harvest on soybean seed composition, and c) to study the potential association between soil properties and leaf chemical element concentration, with seed composition. Selection efficiency in six breeding populations segregating for the low phytate and low stachyose traits was studied by determining the proportion of phenotypically selected lines that carried the alleles for the low phytate trait or low stachyose traits. Yield stability of low phytate/low stachyose lines was studied in a set of 16 breeding lines selected from a breeding population segregating for the low phytate/low stachyose trait, and grown in five Arkansas environments. Planting date effects on seed composition were studied in nine breeding lines planted in early May, late May, and late June at two Arkansas locations in two consecutive years. Delayed harvest effects on seed composition and the association between soil properties and leaf chemical element concentration, with seed composition were studied in the late May planting date. Results showed that the efficiency of marker-assisted selection depended on the type of marker used, whereas phenotype-assisted selection depended on the germplasm that was being screened and on the phenotype used to make breeding selections. Breeders should use marker-assisted selection for low phytate/low stachyose lines only if phenotyping large number of progenies is not time or cost effective. Most of the low phytate/low stachyose lines showed low yield stability. However, one of the low phytate/low stachyose lines studied, R08-6009, showed competitive yield and adaptation to all the environments where the line was evaluated. R08-6009 should be crossed to high-yield lines to generate progeny with greater yield potential. Other lines studied showed moderately high oleic (>45 mg g-1) and low linolenic (
Book Synopsis New Sources of Soybean Seed Composition Traits Identified Through Functional Genomics by : Zhou Zhou
Download or read book New Sources of Soybean Seed Composition Traits Identified Through Functional Genomics written by Zhou Zhou and published by . This book was released on 2020 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean [Glycine max (L.) Merr.] is the world's most widely grown protein/oilseed crop and provides about 70% of global protein meal and 53% of vegetable oil in the United States. Soybean seed oil contains five major fatty acids, from which palmitic acid and stearic acid are two saturated fatty acids, oleic acid improves oxidative stability and linolenic acid is an essential fatty acid for human health. Soybean seed protein and oil are two important quality indices for soybean germplasm breeding. Soluble carbohydrates present in soybean meal provide metabolizable energy in livestock feed. To develop soybean germplasm with improved seed composition traits, it is important to discover novel source of seed fatty acid, protein, and carbohydrates traits. This dissertation aims to develop novel functional genomic technology coupled with an integrated approach for facilitating molecular soybean breeding. In this study, the first objective is to develop a high-throughput TILLING (Targeting Induced Local Lesions IN Genomes) by Target Capture Sequencing (TbyTCS) technology to improve the efficiency of discovering mutations in soybean. The robustness of this technology underlies the high yield of true mutations in genes controlling complex traits in soybean. Soybean mutagenized lines with modified fatty acids composition have been successfully developed to meet the different needs of end users. Altered fatty acids phenotypes have been associated with induced mutations in 3-ketoacyl-acyl carrier protein (ACP) synthase II (GmKASII), Delta-9-stearoyl-acyl carrier protein desaturase (GmSACPD), omega-6 fatty acid desaturase 2 (GmFAD2), and omega-3 fatty acid desaturase (GmFAD3) genes identified through TbyTCS. The second objective is to characterize the soybean acyl-ACP thioesterase gene family through a comprehensive analysis. The additional members have been discovered belonging to 16:0-ACP fatty acid thioesterase (GmFATB) gene family. The mutations at oleoyl-ACP fatty acid thioesterase (GmFATA1A) have been revealed to result in the high seed oleic acid content. The novel alleles of GmFATB genes have also been identified to confer low palmitic acid and high oleic acid phenotypes in soybean seeds. The third objective is to assess the phenotypic variations and correlation among seed composition traits in mutagenized soybean populations. Correlation analyses have been conducted among soybean carbohydrates, protein, and oil content of soybean mutagenized populations and germplasm lines. Chemical mutagenesis played an essential role in soybean breeding to generate novel and desired seed composition traits.
Book Synopsis Genomic Selection for Yield and Seed Composition Stability in an Applied Soybean Breeding Program by : Benjamin Mark Harms
Download or read book Genomic Selection for Yield and Seed Composition Stability in an Applied Soybean Breeding Program written by Benjamin Mark Harms and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stability traits are of primary importance in plant breeding to ensure consistency in phenotype across a range of environments. However, selection efficiency and accuracy for stability traits can be hindered due to the requirement of obtaining phenotype data across multiple years and environments for proper stability analysis. Genomic selection is a method that allows prediction of a phenotype prior to observation in the field using genome-wide marker data and phenotype data from a training population. To assess prediction of stability traits, two elite-yielding soybean populations developed three years apart in the same breeding program were used. The individuals in each population were tested across three years and seven or more environments, allowing for calculation of observed stability and assessment of prediction accuracy. The primary goal of this research was to provide an overview of genomic selection for yield stability, protein content stability, and oil content stability in an applied soybean breeding program. Factors affecting prediction accuracy were assessed, including SNP density, SNP marker type, and stability measure. Briefly, predictive abilities were low across all stability traits and stability measures for prediction across populations, ranging from -0.01 to 0.37. During applied prediction of non-parametric measures for yield stability, we obtained rank coincidence of roughly 0.65. When individuals in the top half of predicted stability are selected, roughly 65% of those individuals are expected to be in the top half of observed stability. For prediction of protein and oil content stability for static environmental variance stability, we obtained rank coincidence of 0.59 and 0.58. While predictive abilities were too low for use in a breeding program, rank coincidence gave more promising results for applied genomic selection for stability traits. With improvement in methods such as prediction model, SNP type, and greater training and validation phenotype environments, there is potential for genomic selection to effectively improve stability in a breeding program by implementing selection at an early stage when phenotype data are insufficient to select for stability.
Book Synopsis Identification and Confirmation of Quantitative Trait Loci for Seed Protein and Oil Content of Soybean by : Jiao Wang
Download or read book Identification and Confirmation of Quantitative Trait Loci for Seed Protein and Oil Content of Soybean written by Jiao Wang and published by . This book was released on 2013 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein and oil are the major chemical constituents of soybean seed that affect the quality of soyfood, feed, and oil products. Therefore, soybean cultivars with high protein and/or high oil are desirable for the soyfood and feed markets. Use of molecular-marker-assisted selection will facilitate the breeding process of such cultivar development. The objectives of this research were to identify new quantitative trait loci (QTL) and confirm previously reported QTL associated with seed protein and oil content by using simple sequence repeat (SSR) markers and single nucleotide polymorphism (SNP) markers. Two recombinant inbred line (RIL) populations consisting of 242 individuals from R05-1415 (high protein/low oil) x R05-638 (low protein/high oil) (population 1) and 214 individuals from R05-4256 (high oil/low protein) x V97-1346 (low oil/high protein) (population 2) were used in QTL mapping. F2 plants from the mapping populations were used for SSR/SNP genotyping. In the marker screening, 120 out of 626 SSR and 1652 out of 5361 SNP markers were polymorphic. The RILs from both populations were grown in a randomized complete block design in Argentina in 2010, Stuttgart and Keiser, AR in 2011 and 2012. Seed from F2:3, F2:4 and F2:5 lines were tested for protein and oil content by using near infrared transmittance technique based on 13% moisture. Protein and oil content in both RIL populations exhibited a typical normal distribution. Single marker analysis (SMA) and composite interval mapping (CIM) revealed two novel oil QTL on chromosomes 14 and 6 in population 2 which account for 17% and 13% of the oil content variation, respectively. A minor protein QTL was confirmed on chromosome 14. One major QTL with large effect was confirmed on chromosome 20 across genetic populations, locations, and years; this QTL has opposite effects on seed protein and oil content. Eight new SNP markers flanking this QTL region on chromosome 20 were identified in population 2. These new and confirmed QTL along with linked molecular markers for seed protein and oil content can be used for marker-assisted selection for seed composition improvement in soybean breeding programs.

Accessions and Subsequent Mapping for Seed Composition and Agronomic Traits in a RIL Population written by Thang Cao La and published by . This book was released on 2018 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relatively low genomic variation of current U.S. soybean [Glycine max (L.) Merill] cultivars constrains the improvement of grain yield, seed quality, and other agronomic traits within soybean breeding programs. Recently, a substantial effort has been undertaken to introduce novel genetic diversity present in wild soybean (Glycine soja Siebold & Zucc.) into new elite cultivars, in both public and private applied soybean breeding programs. The objectives of this research were to evaluate the phenotypic diversity within a core collection of 80 G. soja plant introductions (PIs) in the United States Department of Agriculture National Genetic Resources Program that were collected in China, Japan, Russia, and South Korea, and to analyze the correlations between agronomic and seed composition traits. Field tests were conducted in Missouri and North Carolina during three years, 2013, 2014, and 2015, in a randomized complete block design (n=3). The phenotypic data collected included plant maturity date, seed weight, and the seed concentration of protein, oil, essential amino acid, fatty acid, and soluble carbohydrates. Analyzing the data from six environments, we found genotype was a significant (p

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Food-grade soybeans are a specialty crop with unique chemical and physical seed quality requirements. The tofu production market requires large, round soybean seed with a clear hilum and high protein content. The aim of this project was to detect QTL responsible for traits important in food-grade soybeans, and to provide information for the selection of food-grade soybeans in a breeding program. This study assessed seed shape, size, density, weight, protein content, and oil content in two independent populations of breeding lines and cultivars as well as textural traits of the tofu produced from a subset of those. By identifying the relationship between seed traits and tofu texture, the previously established positive correlation between seed protein content and the stiffness and gel strength of tofu were confirmed. Little to no correlations between seed size and shape measurements and the texture of tofu were detected, indicating that this consumer preference for large, round seeds may not relate to tofu quality. The effects of selection for specialty traits on the genetic differentiation within a breeding program were assessed, results shown that both parental and progeny selection contributed to genetic differentiation and population structure. Association mapping was conducted with 504 markers in a population of 242 breeding lines and cultivars, leading to the identification of 50 significant marker-trait associations. Of the 27 significant associations tested in another independent confirmation population consisting of 152 lines or cultivars, 12 were confirmed. These results can be directly applied to increase selection efficiency in a breeding program.
