“…The results obtained from the variance component analysis of the agronomic features and grain composition of chickpea seeds showed statistically significant ( p < 0.001) differences of G, E, and G × E interaction effects (Table 5). The high environmental variability was confirmed by ANOVA components, which showed that although genotype, environment, and G × E interaction were significant ( p < 0.001) for all traits, environment was the most important source of variation for most of them, which is common in MET (Marioli Nobile et al., 2023).…”

The environment to which a crop is exposed during the growing season has a significant impact on seed composition. The objectives of this study were to (1) estimate the contribution of genotype (G), environment (E), and their interaction (G × E) to the agronomic features and seed quality of chickpea and (2) identify climatic variables that significantly affect chickpea nutritional composition. A total of 10 pre‐commercial and commercial cultivars of Cicer arietinum L. were evaluated in 15 environments in Argentina. Average plant height ranged between 44.7 and 55.2 cm, 100‐seed weight was 38 and 27 g, and grain yield was 750 and 1500 kg ha−1 for kabuli and desi chickpea, respectively. The results obtained from the variance component analysis showed statistically significant (p < 0.05) contributions of the effects of G, E, and G × E interaction on the nutritional quality of chickpea seeds. Protein, carbohydrates, and mineral content were mostly affected by E, whereas oil content was G‐dependent. Only tocopherols were affected by G × E interaction. The total phenotypic variance is mostly composed of environmental effects captured during the seed filling period. High mean daily air temperature had a negative effect on carbohydrates and increased protein and mineral content. The fatty acid profile and gamma tocopherol contents were affected by accumulated precipitation and evapotranspiration. Air humidity was negatively correlated with protein content and iodine value. Results from this research are useful for breeders to broaden the genetic background of chickpea genotypes and for farmers to identify climatic conditions that impact grain quality.

There are three main components of soybean (Glycine max (L.) Merr.) seeds: protein, oil, and residual. The residual fraction includes soluble and insoluble carbohydrates, lignin, and minerals. Among soluble carbohydrates, the presence of raffinose family of oligosaccharides (RFOs) has poor nutritional value (i.e., raffinose and stachyose), and the inability of monogastric animals to digest them limits the potential use of soybean meal for food and feed applications. Our objective was to understand how different environmental conditions impact soybean seed quality, particularly the concentration of the residual fraction and its components. Nine commercial genotypes from three maturity groups were sown on early and late dates. The concentration of insoluble carbohydrates + lignin was positively associated with seed weight (r = 0.67) and negatively associated with the mean temperature during the seed‐filling period (R5–R7; r = −0.61). Within soluble carbohydrates, RFOs were negatively influenced by the mean temperature at the beginning of the seed‐filling period (R5–R6; r = −0.37), while sucrose concentration showed the opposite effect (r = 0.43). In contrast, precipitation exhibited a positive correlation with RFOs, whereas sucrose displayed a negative correlation (r = 0.38 and r = −0.42). This study showed that the decrease in protein concentration was related to the increase in the residual fraction of the seeds, and higher temperatures during seed‐filling period impacted the residual composition of the seeds, specifically by reducing RFO concentration.
