Effect of genotype, environment, and their interaction on chemical composition and antioxidant properties of low-linolenic soybeans grown in Maryland.
Eight soybean genotypes grown in three environments in Maryland were analyzed for total phenolic content (TPC), antioxidant capacity, isoflavone composition, lutein, tocopherols, fatty acid composition, and oil content. Fatty acid composition, isoflavones, lutein, tocopherols, and specific antioxidant assays had significant variation by genotype (G) (P < 0.05). Environment (E) had a significant effect on fatty acids, lutein, individual tocopherols, oxygen radical absorbance capacity (ORAC), and the isoflavone glycitein (P < 0.05). In addition, the interaction between genotype and environment (G x E) showed a significant effect on antioxidant capacity, isoflavones, lutein, tocopherols, and fatty acids (P < 0.05). Factorial designed analysis of variance of all data indicated that G had a larger effect than E on the majority of fatty acids, total isoflavones, lutein, and total tocopherols. E had a larger effect than G on stearic acid (18:0), glycitein, delta-tocopherol, and ORAC. The results of this study show that the genotype, growing environment, and their interactions in Maryland-grown soybeans may alter the levels of specific health-enhancing properties.
