This book was released on 2013 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybeans with seed oil high in oleic acid content have been developed and are desired by oil processors because of improved oxidative stability for broader use in food, fuel and other products. Conventional soybean lines with 80% oleic acid content were generated by combining two mutant genes, mutant S117N FAD2-1A allele from 17D and mutant P137R FAD2-1B allele from PI283327. Thirty five F4:7 high oleic lines with these mutant FAD2-1A and FAD2-1B genes were compared to thirty five F4:7 normal or wild type oleic acid lines for seed contents of the five fatty acids common to soybean, total oil content, total protein content, and seed yield from five crosses grown in six environments. The high oleic genotypes averaged >75% oleic acid content and concentrations of palmitic and linolenic acids were significantly lower (30% lower) than their normal oleic acid counterparts in each environment. When averaged across all locations and populations, seed yield of the high oleic lines were within 2% of the normal oleic lines. Because of the negative correlation of protein with oil content and seed yield shown in many other studies, it was surprising that these high oleic lines averaged significantly higher in protein and oil with similar yield compared to normal oleic lines. These results provided evidence that high oleic soybeans can have comparable yields with the potential to generate more oil with greater functionality and higher protein meal for improved feed and food value compared to soybeans with normal oleic acid content from the same cross.

Book Synopsis Heritability and Genetic Gain of Seed Protein, Oil, and Yield Among RIL of Soybean by : Benjamin T. Wiggins
Download or read book Heritability and Genetic Gain of Seed Protein, Oil, and Yield Among RIL of Soybean written by Benjamin T. Wiggins and published by . This book was released on 2012 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean is a remarkable crop that is used in many aspects of our everyday lives. The seed protein is used primarily for livestock feed, though it is becoming more available as a meat substitute for human consumption. Soybean oil is used in many products such as plastics, foods, and industrial products. Seed yield is the major trait that is selected for in a breeding program. A population of 239 F4 derived RIL from the cross of USG 5601T × U99-310255 was used to calculate heritability estimates by parent offspring regression and on an entry mean basis. This population was grown in 2009 as unreplicated F4:6 plant rows at the East Tennessee Research and Education Center (ETREC) in Knoxville, TN. In 2010, the F4:6 generation was grown as two replications with two locations, ETREC and Highland Rim Research and Education Center (HRREC) in Springfield, TN. In 2011, the F4:-- generation was grown at ETREC, HRREC, and at the Research and Education Center at Milan (RECMLN) in Milan, TN. Averaged over two years (2010 and 2011) and 5 environments exhibited a range of 1928.7 to 3033.6 kg ha−1 with a mean of 2325.7 kg ha−1 for seed yield, 398.4 to 451.8 g kg−1 with a mean of 426.8 g kg−1 for seed protein concentration, and 201.1 to 224.6 g kg−1 with a mean of 213.7 g kg−1 seed oil concentration. On an entry mean basis, a heritability estimate of 0.85 for seed protein concentration was observed. However, a parent-offspring regression of F4:6 to F4[subscript :]-- revealed an estimate of 0.43 (R2=0.26). For seed oil concentration, heritability estimate on an entry mean basis was 0.78 and the parent-offspring regression was 0.11 (R2=0.01). Seed yield exhibited heritability estimates of 0.23 (R2=0.09) and 0.38 for parent-offspring regression and entry mean basis respectively. Genetic gains were calculated for all traits through selections for the top 5, 10, 15, and 20% of RILs for seed yield, seed protein, and seed oil concentration. Improvements in these traits were achieved singularly and could be selected for multiple traits when phenotypic correlations are considered.

Book Synopsis Genomic Regions Involved in Seed Protein, Oil, and Carbohydrate Concentration in Soybean by : Samantha J. McConaughy
Download or read book Genomic Regions Involved in Seed Protein, Oil, and Carbohydrate Concentration in Soybean written by Samantha J. McConaughy and published by . This book was released on 2017 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybeans [Glycine max (L.) Merr.] are processed for their high-quality vegetable oil and protein meal for feed, food, and industrial applications but, because of the high negative correlations between seed protein and oil concentration, it has been difficult to develop soybean lines with concomitant increases in both protein and oil. Previous studies considered only seed protein or oil concentration. This study is unique in that populations were developed using parental lines that differed in their protein, oil, and total carbohydrate concentrations in the mature seed. Two soybean populations were developed using soybean accession PI 547827 with lower total sugars as a common parent, crossed to two different soybean lines with modified protein and oil concentrations. The objectives were to identify quantitative trait loci (QTL) related to seed protein, oil, and carbohydrate concentration as well as for individual sugars sucrose, raffinose, and stachyose. For each of the two crosses, F4-derived recombinant inbred lines (RIL) were developed through single seed descent resulting in 526 and 404 RILs, respectively. Genotypes were determined for F4 plants by genotyping-by-sequence (GbS), resulting in 1,650 to 2,850 polymorphic SNPs used for QTL analyses. Populations were grown in an augmented design in two Nebraska and one Puerto Rico environment to evaluate seed composition, yield, and maturity. The QTL analyses identified 23 novel QTL across all seed composition traits, protein, oil, sum(p+o) or carbohydrate concentration, and each of the sugars on 17 different linkage groups. Ninety nine percent of the lines in the high protein cross, and 100% of the lines in the high oil cross exceeded processor targets of 11 pounds of oil per bushel and a soybean meal with greater than 47.5% protein. Correlations between yield and the sum(p+o) were either zero or slightly positive, indicating that it should be possible to identify high-yielding lines with increased seed protein and oil concentration. Populations like these, and the QTL identified here, will be useful in achieving those objectives to provide more value for both the processor and producer.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean is mainly cultivated for its oil and high quality protein meal for feed, fuel and food uses. Achieving an improved balance of protein and oil in the seed, along with yield will enhance crop value. In practice, this has been difficult to achieve due to significant negative correlations of oil and protein, and the mostly negative relationship reported between seed protein concentration and yield. Most previous studies have focused on increasing seed oil concentration (SOC) or seed protein concentration (SPC) individually, and a few focused on decreasing raffinosacharides to improve digestibility and metabolizable energy of the feed for monogastric animals. None of the studies to date have considered improving the balance of SOC and SPC by also considering variation in total soluble sugars, which comprise the third largest component in soybean seed. Three related bi-parental recombinant inbred line (RIL) populations were developed by crossing two plant introduction lines that have lower total sugar concentration with two high-yielding soybean lines having higher SOC resulting in two pairs of half-sib populations. The objectives of this study were to identify genomic regions that influence oil, protein and carbohydrate concentrations in the seed in three uniquely structured bi-parental RIL populations using Molecular Inversion Probes (MIPs) markers, and evaluate relationships among seed composition traits and seed yield, seed weight and plant maturity from multiple environments. In total, 51 QTLs for seed, seed composition and plant traits were mapped on 17 chromosomes. All populations showed transgressive segregation for the sum of seed oil+protein concentration (SUM) in both directions but showed little transgressive segregation for SOC or SPC in two populations. There was a positive correlation of SOC and SPC with the SUM in two populations and a near to zero relationship of SUM with plot yield. Over the three populations, about 85% of the lines met processor targets of 10-12 pounds of oil per bushel and would produce 48% protein meal. The selected lines from this study could be further evaluated for yield and desirable agronomic traits in multi-location trials, which could lead to higher yielding soybean lines with improved seed composition. This work will ultimately lead to higher profitability for both the processors and farmers.

Book excerpt: BACHLAVA, ELENI. Genetic Control of High Oleic Acid Seed Content in Soybean. (Under the direction of Andrea J. Cardinal and Ralph E. Dewey) The increase of oleic acid concentration in soybean [Glycine max (L.) Merr.] oil improves its nutritional value and oxidative stability; therefore, the incorporation of the high oleate trait in soybean germplasm is required for the commercial success of soybean oil. Little is known, however, about the response to selection for higher oleate content, which is dependent on its heritability in breeding populations, and the correlated responses of other fatty acids and agronomic traits to selection for oleate content, which depends on their genetic correlations with oleate. Furthermore, the lack of knowledge on the genetic factors underlying oleate variation in soybean oilseeds hampers the use of marker assisted selection for high oleate content in soybean breeding programs. The results of this study suggested that oleate heritability was sufficiently high that early generation selection can be effective when practiced on unreplicated lines grown at a single environment. Moreover, this study indicated that selection for higher oleate will result in lower linoleate, linolenate and palmitate content in soybean oil. Also, the significant negative correlation between oleate content and yield implied that the development of high oleate germplasm may be hindered by lower yields. The isoforms of FAD2 gene, which catalyze the desaturation of oleate to linoleate during fatty acid biosynthesis, were mapped in order to investigate their cosegregation with the oleate quantitative trait loci (QTLs) identified. FAD2-1A and FAD2-1B mapped on linkage groups O and I, respectively, while the closely linked FAD2-2A and FAD2-2B isoforms mapped on linkage group L of soybean genome. An oleate QTL with moderate effects was reported in the proximity of FAD2-1B on linkage group I. Also, an oleate QTL with moderate effects was detected on linkage group F, wh.

Alaswad and published by . This book was released on 2014 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybeans are among seeds the common plant foods that contains high protein contents and high oil. The protein provides about 35 to 38 percent of the seeds calories compared to around 20 to 30 percent in other legumes and many animal products. The quality of soy protein is notable and approaches the quality of meat and milk. Unlike many other good sources of protein, soybeans are low in saturated fat and are cholesterol-free. Its proteins provide all the important amino acids, most the amounts needed by humans (NSRL, 2010). As the most consumed vegetable oil in the world, soybean oil has been used substantially in the food industry (Soystats, 2010). Its utilization is determined by its fatty acid composition, with commodity soybean oil typically 13% palmatic acid (16:0), 4% stearic acid (18:0), 20% oleic acid (18:1), 55% linoleic acid (18:2), and 8% linolenic acid (18:3). The change of fatty acid profiles to improve soybean oil quality has been a long time goal of many researchers throughout the world. Biodiesel is an up and coming trend in energy production. Breeding effort can be undertaken in order to produce a higher energy profile soybean oil. Using ethyl-methanesulfonate (EMS) mutagenesis effects on DNA, significant changes to the genes and gene network underlying the protein and oil profile can be achieved. These changes are hard to accomplish using standard breeding techniques. In addition, high amount of linolenic and stearic acid are very important for fuel and biodiesel production, but are not good for food production due to the fact that such oil is oxidized easily and the food goes rancid quickly. However, soybean oil with elevated amount of oleic acid is desirable for food, because this monounsaturated fatty acid improves the nutrition and oxidative stability of soybean oil compared to other oils. In order to improve the quality of soybean oil and processed foods, chemically mutagenized soybeans have been developed in this project. Seeds harvested from individual M3 and M4 plants (from 2 successive years 2012 and 2013) were analyzed for protein content, oil composition, and content. Moreover, seven phenotypic traits including oil analysis (stearic, palmitic, oleic, linolenic and linoleic), seed protein content, weight of the seeds (High yield), seeds color, stem length, germination rates, and branch architecture were collected and analyzed in this project of soybean `Forrest' mutagenized population. The result of this research showed that there were 25 significantly different lines (p
