The random amplified polymorphic DNA (RAPD) technique was used to evaluate both genetic diversity among 19 soybean accessions included in the Czech National Collection of Soybean Genotypes and their potential as a new source of genetic variations for soybean breeding programs. Only 22 of all the 40 random primers used in RAPD reactions showed polymorphism acceptable for an effective characterisation of these accessions. Altogether 122 highly reproducible RAPD fragments were generated, 55 of them were polymorphic (46%). However, because of the previously observed low degree of RAPD polymorphism in the case of Glycine max, fragments with low level of informativeness were evaluated, too. Presented results enable the selection of genetically distinct individuals. Such information may be useful to breeders willing to use genetically diverse introductions in soybean improvement process.

O presente trabalho foi realizado com o objetivo de avaliar os teores de óleo e proteína dos grãos em cultivares de soja em função do retardamento da colheita e verificar a influência da época de semeadura sob condições de baixa latitude. No ano agrícola de 2015/16, foram realizados dois ensaios de competição de cultivares de soja em Palmas-TO, sendo o primeiro instalado em 17 de dezembro de 2015 e o segundo em 04 de janeiro de 2016. O delineamento experimental utilizado em cada época de semeadura foi de blocos casualizados com setenta tratamentos e cinco repetições. Os tratamentos foram dispostos em um esquema de parcelas subdivididas, representados por dez genótipos de soja (PRISMA, TMG 132 RR, M 8647 RR, M 8372 RR, BONUS, RAÇA, ST 820 RR, OPUS, TMG 1180 RR e M 9144 RR), nas parcelas, e por sete estádios de colheita dos grãos (R6, R7, R8, R8+7, R8+14, R8+21 e R8+28 dias), nas subparcelas. Houve efeito das épocas de plantio e dos estádios de colheita nos teores de óleo e proteína dos grãos. As cultivares apresentaram comportamentos diferenciados nas duas épocas de semeaduras, a cultivar M9144 RR obteve um crescente aumento nos teores de proteína na segunda época com retardamento da colheita dos grãos. A partir do estádio R8 de desenvolvimento, o teor de óleo nos grãos de três cultivares foi maior na primeira época de semeadura. Na segunda época, quatro cultivares mostram aumento no teor de óleo a partir de R8.Palavras-chave: Glycine Max L.; retardamento; composição química dos grãos. EPOCH AND AFTER DELAYED OF SOYBEAN HARVEST VISUALIZING OIL AND PROTEIN PRODUCTION  ABSTRACT: The present work was carried out with the objective of evaluate the oil and protein contents of the grains in soybean cultivars as a function of the harvest delay and to verify the influence of the sowing season under conditions in low latitude. In the agricultural year 2015/16, two competition trials of soybean cultivars were carried out in Palmas-TO, the first one being installed on December 17, 2015 and the second on January 4, 2016. The experimental design used at each time were randomized blocks with seventy treatments and five replications. The treatments were arranged in a scheme of subdivided plots, represented by ten soybean genotypes (PRISMA, TMG 132 RR, M 8647 RR, M 8372 RR, BONUS, RAÇA, ST 820 RR, OPUS, TMG 1180 RR e M 9144 RR, on the plots, and seven stages of grain harvest (R6, R7, R8, R8+7, R8+14, R8+21 e R8+28 dias) in the subplots. There was an effect of planting times and harvest stages on the oil and protein contents of the grains. The cultivars presented different behaviors in the two sowing seasons; the cultivar M9144 RR obtained an increasing increase in the protein content in the second season with grain harvest delay. From the R8 development stage, the oil content in the grains of three cultivars was higher in the first sowing season. In the second season, four cultivars show an increase in oil content from R8.Keywords: Glycine max L.; retardation; chemical composition of grains.

The effect of combining lime and phosphate fertilizer on the performance of soybean (Glycine max L.) was investigated in a pot experiment consisting of nine treatments of three rates of lime (0, 4 and 8 t ha−1) in a factorial combination with three rates of phosphorus (0, 15, and 30 kg P ha−1) at Maseno University in western Kenya. There was a significant interaction between the lime and phosphorus rate on the biomass dry weight of soybean. At the rates of 0 and 4 t ha-1 of lime, the biomass dry weight of soybean increased with increasing rates of phosphorus but at 8 t ha-1 of lime, the dry weight of soybean increased from 0 to 15 kg P ha-1 but declined at 30 kg P ha-1. There was however no significant interaction between lime and P rates on grain weight but the effects of both P and lime rate were significant. When applied without lime, 30 kg P ha-1 gave significantly higher grain (5.3 g pot-1) weight than 15 kg P ha-1 (1.6 g pot-1) of soybean, which was also significantly better than the control (0.0 g pot-1). When applied without phosphorus, both lime rates at 4 and 8 t ha−1 significantly increased grain weights of soybean compared to the control, but the grain weights of soybean between the two lime rates did not differ significantly. The highest yields of soybean were obtained when 4 t ha−1 of lime was applied with 30 kg P ha−1 (19 g pot-1). Therefore, this study demonstrates that the ameliorating deleterious effects of soil acidity through liming should simultaneous be accompanied by application of P fertilizer at appropriate rates.

We obtained a new hybrid soybean (Hybrid) by hybridizing β-carotene-enhanced soybean (BCE; Glycine max L.) containing the phytoene synthase-2A-carotene desaturase gene and wild-type soybean (Wild; Glycine soja). To investigate metabolic changes between variants, we performed metabolic profiling of leaves (three growth stages) and seeds. Multivariate analyses revealed significant metabolic differences between genotypes in seeds and leaves, with seeds showing accumulation of phytosterols, tocopherols, and carotenoids (BCE only), indicating co-induction of the methylerythritol 4-phosphate and mevalonic acid pathways. Additionally, Hybrid produced intermediate levels of carotenoids and high levels of amino acids. Principal component analysis revealed metabolic discrimination between growth stages of soybean leaves and identified differences in leaf groups according to different genotypes at 8, 12, and 16 weeks, with Wild showing higher levels of environmental stress-related compounds relative to BCE and Hybrid leaves. The metabolic profiling approach could be a useful tool to identify metabolic links in various soybean cultivars.

<p>Soybean (Glycine max L. Merril) has been cultivated in regions of lowland soils in crop rotation with irrigated rice in order to reduce the infestation of red rice and due to the attractive soybean value in the world market. Soybean cultivation under this condition is subject to possible soil flooding, requiring recommendations of genotypes adapted to this environment. The aim of this study was to evaluate the grain yield of soybean genotypes grown in floodplain environment at three different sowing times. Cultivars used were A 6411 RG, A 7321 RG, BMX Apolo RR, BMX Ativa RR, BMX Energia RR, BMX Potência RR, BMX Turbo RR, IGRA RA 518 RR, IGRA RA 626 RR, IGRA RA 628 RR, NA 5909 RG , NS 6262 RR, NS 7100 RR, RA 728 RR and VMax RR; sown in October, November and December. The experimental design was 15 (cultivars) x 3 (times) factorial with 4 replicates. Significant differences were observed for sowing times and cultivars, as well as for the interaction between the two factors. Cultivars sown in November and December provided higher yields than those sown in October. BMX Turbo RR cultivar showed higher consistency for soybean yield in lowland, considering the sowing times evaluated. For early sowing (October and November), A 6411 RG cultivar presented higher grain yield compared to the other cultivars.</p>
