Agromorphological Characterization of Quinoa (<i>Chenopodium quinoa</i> Willd.) Under Andean-Amazonian Region of Peru.

ABSTRACT: 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 hierarch
