▶ AI Summary
The study evaluated drought tolerance and yield stability of eleven Andean amaranth genotypes (A. caudatus and A. mantegazzianus) across four agroecological zones in Northwest Argentina under irrigated and drought conditions, using linear mixed models and AMMI analysis. Significant genotype and genotype‑by‑environment interactions were detected, with several A. caudatus breeding lines showing both high yield and stability, while a landrace of A. mantegazzianus was stable but low yielding.
