“…Soybean seed oil and oleic acid both were positively correlated with seed weight, whereas stearic acid and linolenic acid were negatively correlated with seed weight (Table 4). This result is consistent with the observations of Kumar et al (2006), Guleria et al (2008), Poeta et al (2016), and Lee et al (2017), who observed that seed size had positive correlations with oil and oleic acid but a negative correlation with linolenic acid when they studied different collections of Glycine max accessions.…”

The relatively low genetic variation of current US soybean [Glycine max (L.) Merr.] cultivars constrains the improvement of grain yield and other agronomic and seed composition traits. Recently, a substantial effort has been undertaken to introduce novel genetic diversity present in wild soybean (Glycine soja Siebold & Zucc.) into elite cultivars, in both public and private breeding programs. The objectives of this research were to evaluate the phenotypic diversity within a collection of 80 G. soja plant introductions (PIs) in the USDA National Genetic Resources Program and to analyze the correlations between agronomic and seed composition traits. Field tests were conducted in Missouri and North Carolina during 3 yr (2013, 2014, and 2015) in a randomized complete block design. The phenotypic data collected included plant maturity date, seed weight, and the seed concentration of protein, oil, essential amino acids, fatty acid, and soluble carbohydrates. We found that genotype was a significant (P < 0.0001) source of variation for maturity date, seed weight, seed protein and amino acids, seed oil and fatty acids, and seed carbohydrates, and significant correlations were observed between numerous traits. The G. soja PIs generally had lower seed weight, higher seed contents of protein, linolenic acid, raffinose, and stachyose, and lower seed contents of oil and oleic acid than the cultivated soybean G. max lines. The information and data collected in this study will be invaluable in guiding soybean breeders and geneticists in selecting promising G. soja PIs for research and cultivar improvement.

“…Moreover, previous studies documented that seed coat color and seed weight influence the levels of other secondary metabolites including isoflavones, anthocyanins, tocopherols and phenolic compounds in soybeans [13,[17][18][19]. Unlike these, however, studies that investigate the effects of seed-related characters on protein, oil and fatty acid contents in soybeans are still limited [3,8,20,21]. In general, analyzing the effects of these factors on protein, oil, and fatty acid contents could be a significant input for the development of improved soybean cultivars [16].…”

Soybean seeds are one of the best sources of plant-based high-quality proteins and oils. The contents of these metabolites are affected by both environmental and genetic factors. In this study, 49 soybean germplasms were cultivated in Korea, the contents of total protein, total oil and five fatty acids were determined, and the influences of seed coat color and seed weight on each were assessed. The total protein and total oil contents were evaluated using Kjeldahl and Soxhlet methods and were in the ranges of 36.28-44.19% and 13.45-19.20%, respectively. Moreover, the contents of individual fatty acids were determined as area percentage from acquired gas-chromatography peaks. The contents of palmitic, stearic, oleic, linoleic and linolenic acids were in the ranges of 9.90-12.55, 2.45-4.00, 14.97-38.74, 43.22-60.26, and 5.37-12.33%, respectively and each significantly varied between the soybean germplasms. Unlike total oil and fatty acid contents, total protein content was not significantly affected by both seed coat color and seed weight. Cluster analysis grouped the soybeans into two classes with notable content differences. Fatty acids were the main factors for the variabilities seen between the soybean germplasms as observed in the principal component analysis. Correlation analysis revealed a significant but negative association between total oil and total protein contents (r = -0.714, p < 0.0001). Besides, a trade-off relationship was observed between oleic acid and linoleic acid (r = -0.936, p < 0.0001) which was reflected with respect to both seed coat color and seed weight. Among all colored soybeans, pale-yellow soybeans had the highest and the lowest levels of oleic acid and linoleic acid, respectively each being significantly different from the rest of colored soybeans (p < 0.05). Likewise, oleic acid content increased with seed weight while that of linoleic acid decreased with seed weight (p < 0.05). In general, this study showed the significance of seed coat color and seed weight to discriminate soybean genotypes, mainly in terms of their fatty acid contents. Moreover, the soybean germplasms with distinct characters and fatty acid contents identified in this study could be important genetic resources for cultivar development.

“…Oil content and fatty acid composition vary between positions of seeds on the stem axis (Guleria et al 2007(Guleria et al , 2008. Seeds that develop in the upper one fourth of the plant contain a higher concentration of protein and lower concentration of oil than seeds from lower one fourth of the plant (Escalante and Wilcox 1993a, b) This difference in the oil and protein content at various nodal positions of the stem axis has been described to be due to variation occurring in nutrients and assimilates supply and other factors at each position.…”

This investigation was conducted in order to determine the degree of biochemical changes during natural ageing of soybean seeds borne on different positions on stem axis. Biochemical analysis of field grown soybean seeds revealed significant differences in their oil and protein contents as a function of nodal positions. Both oil and protein content decreased after 180 days of storage (DOS) at all the nodal positions. Proportions of membrane lipids in seeds were less in basal as compared to apical positions and their proportion in stored seeds also decreased with increasing storage periods. The content of starch, total soluble sugars and reducing sugars in seeds decreased during storage for 180 days but it didn't show positional variations in their contents. The extent of lipid peroxidation increased during storage was associated with the corresponding decrease in the activities of antioxidant enzymes viz catalase and peroxidase in seeds. Seeds at basal positions showed higher rate of lipid peroxidation and lower peroxidase activity as compared to apical positions. Results suggest that soybean seeds collected from basal positions showed higher deteriorative changes during storage in comparison to apical positions that might be related to higher lipid content in seeds from basal portion of soybean stem axis as compared to apical portion.
