Quinoa (Chenopodium quinoa Willd.) is an Andean pseudocereal of high nutritional value and remarkable phenotypic diversity, recognized as a strategic crop for food security under increasing climatic variability. In this study, the agromorphological diversity of 158 accessions cultivated in the Andean–Amazonian region of Peru was evaluated with the aim of identifying superior materials for conservation and breeding programs. The experiment was conducted using an augmented design that included three check cultivars (INIA 415 Pasankalla, INIA 420 Negra Collana, and Blanca Juli). Diversity in eleven qualitative traits was quantified using the Shannon–Weaver (H′) and Nei (He) indices, whereas twelve quantitative traits were analyzed through principal component analysis (PCA) and hierarchical clustering. The results revealed substantial intra- and inter-accession variability, with He values ranging from 0.21 to 0.76 and H′ values from 0.40 to 1.79, reflecting marked differences in growth habit, panicle morphology, stem pigmentation, and tolerance to Peronospora variabilis and Epicauta spp. Multivariate analyses identified three contrasting groups and enabled the selection of outstanding accessions, including UNTRM-367-1149, UNTRM-367-1107, UNTRM-367-1078, UNTRM-367-1079, UNTRM-367-1081, UNTRM-367-1095, and UNTRM-367-1104, characterized by high yield potential, favorable reproductive architecture, early or intermediate maturity, and low downy mildew severity. These accessions represent promising genetic resources for developing quinoa varieties adapted to transitional Andean–Amazonian environments, contributing to improved crop productivity and resilience.

Common bean ( Phaseolus vulgaris L.) grains represent a major source of plant‐based protein and essential micronutrients; however, their consumption is constrained by prolonged cooking times and variable nutritional profiles. This study characterized the morphological, culinary, and nutritional diversity of 36 common bean accessions collected from the northern Andean region of Peru to identify accessions combining rapid cooking ability with high nutritional quality. After 3 months of postharvest storage, six qualitative and three quantitative seed traits were evaluated. Phenotypic diversity was quantified using Nei's (He) and Shannon–Weaver's (H′) indices. Hydration capacity (HC), cooking time (CT), and seed concentrations of iron (Fe), zinc (Zn), and protein (Prot) were analyzed in a completely randomized design with three replications. Quantitative data were subjected to descriptive statistics, principal component analysis (PCA), cluster analysis, and Pearson correlation. Substantial intra‐ and inter‐accession morphological variability was detected (He = 0.64; H′ = 1.48). A strong negative correlation was observed between HC and CT ( r = −0.92), whereas Fe and Zn concentrations showed a moderate positive correlation ( r = 0.78). The fastest‐cooking accessions were UNTRM3351017 (5.33 min), UNTRM3351009 (5.67 min), and UNTRM3351001 (6.33 min). The highest Prot levels were recorded in UNTRM3351017 (26.60%), UNTRM3351013 (25.10%), and UNTRM3351001 (24.77%). For mineral concentration, UNTRM3351029 (Fe: 176.58 ppm; Zn: 52.07 ppm) and UNTRM111034 (Fe: 152.39 ppm; Zn: 44.42 ppm) exhibited the highest concentrations. These results demonstrate useful phenotypic variability within Andean germplasm and identify promising accessions under the evaluated conditions; however, further studies are required to confirm their stability and potential in breeding programs.
