-The soybean has an important role in the area of biodiesel, due to having a productive potential and technical feasibility able to meet the growing demand for renewable fuels. In the agricultural year of 2009/10, four competitive trials of soybean cultivars were carried out, two on the Campus of Palmas University and the other two on the University Campus at Gurupi, with a study of genetic divergence being undertaken. At each location, the cultivars were trained under conditions of both high and low phosphorus (150 kg ha -1 P 2 O 5 and 30 kg ha -1 P 2 O 5 respectively). The experimental design employed for each trial was of randomised blocks with three replications and 11 treatments. The percentage of oil as a characteristic was studied, and the efficiency of phosphorus usage by the cultivars determined employing the methodology adapted from Fischer (1983). Genetic divergence was evaluated using multivariate procedures: the generalised Mahalanobis distance and Tocher's optimisation method for clustering. In the study of genetic divergence, each test represented a distinct variable in the multivariate model. The cultivars M-SOY 9350, M 8766RR and BR/EMGOPA 314 are the most suitable for the production of biodiesel. The hybrids M 8766RR x M 9056RR, BR/EMGOPA 314 x M 9056RR, P98R91 x M 9056RR are promising for obtaining segregating populations to be used for their oil content.

-The objective of this work was to evaluate the chemical and physical characteristics of grains of soybean (Glycine max) cultivars for food processing. The soybean cultivars evaluated were: grain-type -BRS 133 and BRS 258; food-type -BRS 213 (null lipoxygenases), BRS 267 (vegetable-type) and BRS 216 (small grain size). BRS 267 and BRS 216 cultivars showed higher protein content, indicating that they could promote superior nutritional value. BRS 213 cultivar showed the lowest lipoxygenase activity, and BRS 267, the lowest hexanal content. These characteristics can improve soyfood flavor. After cooking, BRS 267 cultivar grains presented a higher content of aglycones (more biologically active form of isoflavones) and oleic acid, which makes it proper for functional foods and with better stability for processing, and also showed high content of fructose, glutamic acid and alanine, compounds related to the soybean mild flavor. Because of its large grain size, BRS 267 is suitable for tofu and edamame, while small-grain-sized BRS 216 is good for natto and for soybean sprouts production. BRS 216 and BRS 213 cultivars presented shorter cooking time, which may be effective for reducing processing costs.Index terms: Glycine max, amino acids, fatty acids, hexanal, isoflavones, lipoxygenases, sugars. Composição química e física de soja tipo grão e tipo alimento para o processamento de alimentosResumo -O objetivo deste trabalho foi avaliar as características químicas e físicas de grãos de cultivares de soja (Glycine max) para o processamento de alimentos. As cultivares avaliadas foram: tipo grão -BRS 133 e BRS 258; tipo alimento -BRS 213 (desprovida de lipoxigenases), BRS 267 (tipo hortaliça) e BRS 216 (tamanho de grão pequeno). As cultivares BRS 216 e BRS 267 apresentaram maior teor de proteínas e poderiam promover valor nutricional superior. A cultivar BRS 213 apresentou a menor atividade de lipoxigenases e a BRS 267, o menor teor de hexanal. Essas características podem melhorar o sabor dos alimentos. Com o cozimento, os grãos da cultivar BRS 267 apresentaram maior teor de agliconas (forma biologicamente mais ativa das isoflavonas) e de ácido oleico, o que a torna adequada para alimentos funcionais e com melhor estabilidade para processamento, além de maior teor de frutose, ácido glutâmico e alanina, compostos relacionados ao sabor suave da soja. A cultivar BRS 267, com maior tamanho de grãos, é adequada para tofu e edamame, e a BRS 216, com menor tamanho, é apropriada para natto e para produção de brotos de soja. As cultivares BRS 216 e BRS 213 apresentaram menor tempo de cozimento, o que pode ser eficaz para reduzir os custos do processamento.

“…The soybean grain contains approximately 20% of oil, 38% of protein and 34% of carbohydrates, as well as fibers and inorganic constituents, whose composition varies according to genetics and environmental conditions, from 20 to 40 days before grain maturation (Embrapa, 2010;Sbardelotto & Leandro, 2008).…”

Chemical composition of grains and environmental efficiency in soybeans grown under low latitude conditions

Soybeans are one of the main commodities in Brazil, with soybean oil and meal used as raw material for food and animal feed production. However, information on the chemical characteristics of soybeans produced at different times of the year and on the efficiency of genotypes under low latitude conditions is scarce. This study evaluates the environmental efficiency of soybean genotypes based on oil and protein contents during in-season and offseason periods, in Tocantins State. The experimental design was a randomized block with seventeen treatments (genotypes) and three replicates. The treatments were composed by cultivars TMG 1288 RR; AS 3810 IPRO; CD 2792 RR; CD 251RR; CD 2737RR; SHS 820 IPRO; TMG 1180 RR; M 8766 RR; P 98Y70RR; M 9144 RR and strains 5X6-1; 5X6-2; 5X6-3; 4X6-12; 4X6-17; 4X6-19 and 4X5-2. There was effect of sowing times on the oil and protein contents of the grains. Genotype TMG 1288 RR presented the highest levels of oil and protein. The best sowing time for protein content was the first of the in-season (12/01). For oil content, in turn, the off-season stood out (06/01), evidencing that early sowing resulted in better results. Since the contents of these two elements are inversely proportional, one must verify the desired purpose to choose the material to be used. The identification of superior genotypes by the proposed index was effective only for unfavorable environments.Additional keywords: oil content; protein; sowing times; soybean hybrids. ResumoA soja, uma das principais commodities do Brasil, tem o óleo e o farelo como matéria-prima para a produção de alimentos e ração animal. Entretanto, são escassas as informações sobre as características químicas dos grãos de soja produzidos em diferentes épocas do ano, bem como a eficiência de genótipos em condições de baixa latitude. O presente trabalho teve como objetivo avaliar a eficiência ambiental de genótipos de soja, com base nos teores de óleo e proteína, nos períodos de safra e entressafra no Estado do Tocantins. O delineamento experimental utilizado foi o de blocos casualizados, com dezessete tratamentos (genótipos) e três repetições. Os tratamentos foram constituídos pelas cultivares TMG 1288 RR; AS 3810 IPRO; CD 2792 RR; CD 251RR; CD 2737RR; SHS 820 IPRO; TMG 1180 RR; M 8766 RR; P 98Y70RR; M 9144 RR e pelas linhagens 5X6-1; 5X6-2; 5X6-3; 4X6-12; 4X6-17; 4X6-19 e 4X5-2. Houve efeito das épocas de plantio nos teores de óleo e proteína nos grãos. O genótipo TMG 1288 RR apresentou os maiores teores de óleo e proteína. A melhor época de semeadura para teor de proteína foi a primeira safra (01/12), já para o teor de óleo foi na entressafra (01/06), evidenciando que a antecipação da semeadura proporcionou melhores resultados. Como os teores desses dois elementos são inversamente proporcionais, deve-se verificar a finalidade desejada para poder escolher o material a ser utilizado. A identificação dos genótipos superiores pelo índice proposto foi eficaz apenas para ambientes desfavoráveis.Palavras-chave adicionais: épocas de semeadura; híbridos...
