Interrelationships among seed yield and quality in quinoa: environmental and genotypic determinants

What is it about?

Environmental and genotypic determinants of seed quality is a topic poorly studied in quinoa, an Andean pseudocereal which is gaining promising importance worldwide due to the high protein content of their seeds. The objectives of this study were twofold: first, determine the size and nature of genotype-by-environment interaction for seed quality attributes in this crop; and second, explore the genetically and environmentally determined correlations among seed yield components and seed composition traits.

Why is it important?

Variability in the main seed composition traits in sea level quinoa cultivars was explained mostly by G × S interaction. The choice of genotypes and sowing dates that modify the trade‐offs between the main yield and seed composition traits might contribute to obtain a specific quality and higher yields.
