“…Yield was positively correlated with all examined constituents apart from linoleic and linolenic fatty acids and sucrose. Protein and oil exhibited a negative correlation (r = -0.25) as has been reported by Carrera et al (2011). The sum of essential and non-essential amino acids was each positively correlated with protein content, r = 0.77 and r = 0.93, respectively.…”

Core Ideas Planting date and maturity group decisions can greatly affect yield and composition. Temperature had a significant effect on seed yield and composition. Planting date × maturity group should be chosen based on the product's end use. Soybean [Glycine max (L.) Merr.] production has greatly increased in the upper U.S. Midwest over the last decade, but little information exists regarding the interactive effects of environment and spring management decisions on soybean seed yield and composition. Our objective was to assess the effect of four planting dates (PDs), four cultivar maturity groups (MGs), and ambient temperature between R5 to R8 (T5–T8) on soybean seed yield and composition. Field studies were established between 2014 and 2016 at three locations in Wisconsin and one in Minnesota. Across environmental conditions and management decisions, greater seed yield was positively correlated with protein and oil contents but negatively correlated with linoleic, linolenic, and sucrose contents. Multivariate data analysis showed positive synergies between early planting (late April–early May) and MG 2 for yield, oil, and oleic acid across the examined region. A MG 2 was the highest yielding and a ∼1200 kg ha−1 yield difference was observed between early and late PDs. These results underline the complexity of the soybean yield‐composition relationships. Additionally, the large variability in the responses of constituents to management decisions and temperature variations highlights the importance of a producer knowing the product's end use (e.g., high yield vs. high protein) and accordingly modifying the growing environment by selecting an appropriate PD and MG for the respective region. To provide more accurate recommendations to a broader range of producers, multi‐environment studies are imperative to capture large environmental variability in important soybean production areas across the United States.

“…Accordingly, breeding objectives to develop soybean variety for resolving the imbalance of production and demand of soybeans are diversified with not only high yielding ability but also usability such as high functionality, and tolerance to diseases, insect pests, and stresses (Kim et al 2006). It was repoted that in spite of the same soybean variety, variations of flowering time (Kumar et al 2008), and oil and fatty acid (Shin et al 2009;Carrera et al 2011), crude protein (Kumar et al 2006), and isoflavone (Tsukamoto et al 1995;Carrera et al 2011) contents obviously occur by cultivated environmental conditions. Therefore, one of breeding strategies to achieve the goal to develop soybean varieties with high quality is the selection and application of useful soybean germplasms, which are excellent in yielding ability and principal component contents, and which are remarkably stable in agricultural traits and biochemical compositions affected by environmental factors.…”

We conducted this study to select useful germplasms for investigating the agricultural performances and content variations of proximate composition, fatty acid, and isoflavone of the soybean germplasms grown at two different latitudes, Suwon (37 o 16'N) and Yeoncheon (38 o 12'N), Republic of Korea. The days to flowering of the soybeans grown at Suwon was early by 1 day compared with that at Yeoncheon whereas the days to maturing of the soybeans were not different by latitudes. The Yeoncheon-cultivated soybeans were greater in growth and yield than the Suwon. The crude oil in range of 17.0% to 20.0% had a positive correlation with the yield. There was a strong negative correlation between oleic acid and saturated fatty (palmitic and stearic) acid contents in the seeds producted at Suwon but the Yeoncheon were not significant. The linoleic acid in seeds of the germplasms was contained by 7.3-fold more than the linolenic acid. The malonylgenistin content was the highest among the detected isoflavones and Deapung had the highest total isoflavone content. The content of total isoflavones in the Yeoncheon-producted seeds was high more than that in the Suwon whereas those of Hei nong 44(hou), Tachikogane, and B152 grown at Suwon were significantly lower rather than those at Yeoncheon. However, the difference of latitude seemed to play an important role in the content variations of growth, yield, and fatty acids and isoflavones in the germplasms. Eventually, Tie dou 44 and WIR3722, which were stably outstanding in all the investigated aspects regardless of the growing locations, were selected as useful germplasms.

“…It has been widely documented that soybean seed composition varies with environmental factors, especially during the seed filling period when accumulation of the seed chemical components occurs (Wolf et al, 1982;Wilson, 2004;Carrera et al, 2009Carrera et al, , 2011. The relationship of protein contents (the sum of all amino acids) with temperature (Piper & Boote, 1999;Wilson, 2004) and water availability (Rose, 1988;Boydak et al, 2002;Kumar et al, 2006;Carrera et al, 2009) has also been studied, but results have shown dissimilar patterns.…”

-The objective of this work was to perform a quantitative analysis of the amino acid composition of soybean seeds as affected by climatic variables during seed filling. Amino acids were determined from seed samples taken at harvest in 31 multi-environment field trials carried out in Argentina. Total amino acids ranged from 31.69 to 49.14%, and total essential and nonessential amino acids varied from 12.83 to 19.02% and from 18.86 to 31.15%, respectively. Variance components expressed as the percentage of total variation showed that the environment was the most important source of variation for all traits, followed by the genotype x environment interaction. Significant explanatory linear regressions were detected for amino acid content regarding: average daily mean air temperature and cumulative solar radiation, during seed filling; precipitation minus potential evapotranspiration, during the whole reproductive period; and the combinations of these climatic variables. Each amino acid behaves differently according to environmental conditions, indicating compensatory effects among them.Index terms: Glycine max, environmental variation, multiple linear regression, multi-environment trials, protein composition. Conteúdo de aminoácidos em sementes de soja em função de variáveis climáticasResumo -O objetivo deste trabalho foi realizar uma análise quantitativa da composição de aminoácidos de sementes de soja em função de variáveis climáticas, durante o período de formação do grão. Foram analisados os aminoácidos de amostras de sementes colhidas no momento da colheita a partir de 31 ensaios multiambientais realizados a campo na Argentina. Os aminoácidos totais variaram de 31,69 a 49,14%, e o total de aminoácidos essenciais e não essenciais variou de 12,83 a 19,02% e de 18,86 a 31,15%, respectivamente. Os componentes de variância expressos como percentagem da variação total mostraram que o ambiente foi a fonte de variação mais importante, seguido da interação genótipo x ambiente. Regressões lineares significativas foram detectadas para o conteúdo de aminoácidos em relação a: temperatura média diária do ar e radiação solar acumulada, durante a formação dos grãos; precipitação menos evapotranspiração potencial, durante todo o período reprodutivo; e combinações dessas variáveis climáticas. Cada aminoácido comporta-se de forma diferente de acordo com as variações nas condições ambientais, o que indica efeitos compensatórios entre eles.Termos para indexação: Glycine max, variação ambiental, regressão linear múltipla, ensaios multiambientais, composição de proteínas.
