ABSTRACT Soybean improvement via plant breeding has been critical for the success of crop. The objective this study was to quantify genetic change in yield and other traits that occurred during past 80 yr North American soybean Maturity Groups (MGs) II, III, IV. Historic sets 60 MG 59 49 IV cultivars, released from 1923 2008, were evaluated field trials conducted 17 U.S. states one Canadian province 2010 2011. Averaged over 27 II 26 III site‐years data, estimated rates 23 kg ha –1 MGs 20...
Abstract Soybean is the world’s leading source of vegetable protein and demand for its seed continues to grow. Breeders have successfully increased soybean yield, but genetic architecture yield key agronomic traits poorly understood. We developed a 40-mating nested association mapping (NAM) population 5,600 inbred lines that were characterized by single nucleotide polymorphism (SNP) markers six in field trials 22 environments. Analysis agronomic, SNP data revealed 23 significant marker-trait...
Genetic improvement toward optimized and stable agronomic performance of soybean genotypes is desirable for food security. Understanding how perform in different environmental conditions helps breeders develop sustainable cultivars adapted to target regions. Complex traits importance are known be controlled by a large number genomic regions with small effects whose magnitude direction modulated factors. Knowledge the constraints undesirable resulting from genotype interactions key objective...
Soybean [Glycine max (L.) Merr.] is a globally important crop due to its valuable seed composition, versatile feed, food, and industrial end-uses, consistent genetic gain. Successful gain in soybean has led widespread adaptation increased value for producers, processors, consumers. Specific focus on the nutritional quality of composition food feed further elucidated knowledge bolstered breeding progress. Seed components are historical current targets breeders seeking improve soybean. This...
Globally, soybeans are grown to meet the needs for animal and human nutrition, oil extraction, use in multiple industrial applications. Decades of soybean research, innovative farming methods, higher yielding resistant seed varieties have led increased crop yields. producers utilized enhanced processing methods produce nutritious high-quality meal extracted feed within food industry. Soybeans contain highly digestible proteins processed using various mechanical chemical techniques high...
The effects of high oleic oil full-fat (HO-FF) soybean meal (SBM) on broiler meat quality could lead to value-added food products. This experiment evaluated the dietary normal extruded expelled (NO-EE), (NO-FF), or HO-FF SBM live performance, carcass and parts yield, breast fatty acid composition. Diets were formulated be isoenergetic isonitrogenous. A total 540 Ross-708 male broilers raised floor pens with 18 broilers/pen ten replicates/treatment. Data analyzed in a completely randomized...
Wild soybean (Glycine soja Siebold & Zucc.) has valuable genetic diversity for improved disease resistance, stress tolerance, seed protein content and sulfur-containing amino acid concentrations. Many studies have reported loci controlling composition traits based on cultivated populations, but wild been largely overlooked. In this study, a nested association mapping (NAM) population consisting of 10 families 1107 recombinant inbred lines was developed by crossing accessions with the common...
Abstract Oil accounts for about 50% of the value soybean [ Glycine max (L.) Merr.]. A changing marketplace demands oil with reduced amounts linoleic and linolenic acid to increase shelf‐life increased amount oleic compete heart‐healthy oils. Meal other half crop. Higher protein quantity quality in meal increases its as animal feed human food. USDA‐N6007HOLL is a conventional, maturity group VI (Reg. no. GP‐530, PI 706251) germplasm white flower, gray pubescence, brown pod wall jointly...

Abstract Several leaf traits of soybean ( G lycine max L . M err.), including area LA ), shape LS ) and specific weight SLW may be related to yield. The objective this study was identify novel quantitative trait loci QTL for , in a recombinant inbred line RIL population. phenotype data were collected 2011 2012 93 F 7:10 s using randomized complete block design with 2 replicates each year. Five hundred sixteen single‐nucleotide polymorphism SNP markers the used detect single marker analysis...
ABSTRACT Soybean aphid ( Aphis glycines Matsumura) is a native pest of soybean [ Glycine max (L.) Merr.] in eastern Asia and was detected on soybeans North America 2000. In 2004, the cultivar Dowling described to be resistant aphids with Rag1 gene for resistance. 2006, virulent biotype Ohio reported proliferate gene. The objective survey occurrence populations indicator lines across geographies years. Nine were identified basis their degree resistance importance breeding programs. Naturally...
Abstract Oil value is determined by the functional qualities imparted from fatty acid profile. Soybean oil historically had excellent use in foods and industry; need to increase stability of without negative health consequences has led a decline soybean use. One solution make stable have high oleic (>70%) lower linolenic content oil. Other profile changes are intended target market needs: low‐saturated stearic The objective this study determine interaction trait with other alleles...
Abstract USDA‐N7007 is a non‐GM, maturity group (MG) VII soybean [ Glycine max (L.) Merr.] (Reg. no. GP‐529, PI 705147) germplasm released by the USDA Agricultural Research Service in conjunction with North Carolina December of 2023. high‐yielding, high‐protein derived from wild ( soja Siebold & Zucc; 366122) and small‐seeded MG cultivar N7103. Over 47 combined testing environments Southern Uniform USB Protein Diversity Tests (2018–2021), yielded 98% check mean 102% test mean. The...
Powdery mildew (caused by Microsphaera diffusa Cooke & Peck) is a common disease of soybean in many soybean-growing regions the world and under greenhouse conditions. The previously reported Rmd locus for resistance to powdery was mapped on molecular linkage group J (chromosome 16). We have discovered single dominant gene PI 243540 that provides season-long mildew. objective this study map with PCR-based markers. One hundred eighty-four F2 plants their F(2:3) families from cross between...
High-oleic (HO) soybean may serve as a value-added feed ingredient to enrich poultry meat due its fatty acid content. However, the amino (AA) nutrient digestibility of meal (SBM) made from these soybeans has yet be determined. The objective this study was determine apparent ileal AA (AID) and standardized (SID) high-oleic full-fat (HO-FF) SBM compared normal oleic (NO-FF), extruded expeller (NO-EE), solvent-extracted (SE-SBM) in broilers. A nitrogen-free basal diet (NFD) fed 1 treatment...
High oleic (HO) soybeans may serve as a value-added feed ingredient; providing amino acids and estimating their dietary energy value for broilers is essential. In this study, we determined the apparent metabolizable (AME), AME corrected zero nitrogen retention (AMEn), digestibility, (N) of HO full-fat (HO-FF) soybean compared to solvent-extracted meal (SE-SBM), normal (NO-FF) extruded expeller (NO-EE) soybean.
