ABSTRACTBACKGROUND: Information about the soybean seed chemical profile is valuable for breeding programs aimed at obtaining value-added products to meet the demands of the niche markets. The objective of this study was to determine seed composition of nontransgenic soybean genotypes with specialty characters in different environments of Argentina. RESULTS: Protein and oil contents ranged from 396 to 424 g kg-1 and from 210 to 227 g kg-1, respectively. Oleic and linolenic acid ratio, the general indicator of oil quality, varied from 2.7 to 3.8. The oil contained high levels of total tocopherols (1429 to 1558 mg kg-1) and the meal exhibited high levels of total isoflavones (2.91 to 4.62 mg g-1). The biplot showed that oleic, linoleic and linolenic acids, gamma, delta and total tocopherols, genistin, malonyl daidzin and genistin, acetyl daidzin and glycitin and total isoflavones allowed the greatest discrimination among the genotypes studied. CONCLUSION: Different chemical profiles of each nontransgenic genotype analyzed were established and, therefore, their identity was defined. These results are important for breeders who intend to obtain new genotypes with improved meal and oil quality, as well as for processors and exporters, who could use them directly as raw material for soyfood processing for nutraceutical purposes.
