Although seed chemical composition is genetically controlled, the environment has significant effects on the amount and profile composition constituents. The objective of this research was to assess the contribution of genotype and environment for seed composition constituents such as protein, oil, fatty acids, carbohydrates, and minerals. Field experiments conducted in the midsouth, USA, on soybean, corn, and cotton showed that genotype by environment interaction resulted in a significant variability of these constituents, and that the magnitude of effects was constituent dependent. This variability was due to genotype (genetic background), environment (such as irrigation, soil, insect, and disease pressure), and their interactions. This presentation, using the results from field experiments with soybean, corn, and cotton, demonstrates the complexity of genotype and environment on seed composition. |
