Phenotypic intrapopulation variation in quinoa from the department of Boyacá, Colombia

Quinoa (Chenopodium quinoa Wild.) is an Andean crop that originated from the Andes of South America, with great agronomic, industrial, pharmaceutical potential and also a great capacity to tolerate adverse environmental factors. In Colombia, more accurately in the Department of Nariño, Cauca, Cundinamarca and Boyacá. Shows great genetic variation, both molecular and morphological, which organization remains poorly documented. In Boyacá, there are few studies on the morphological characterization of cultivated materials, and there is no certified planting material, with farmers planting a mixture of materials. Qualitative and quantitative descriptors and principal component and cluster analyses were used to characterize the structure of the intra-population phenotypic variation in Blanca de Jericó quinoa materials grown in the Department of Boyacá. The principal component análisis explained more than 70 % of the observed variation, with the AP, LP, DP, LHS, and AHS characteristics being more variable. The cluster analysis showed grouping by characteristics, such as AP, panicle color, and the presence of pigmented axillae. Results show that the variance in morpho-phenological traits was concentrated at the intra-population, due to high variation at the inter-individual level. A more efficient selection process should be carried out to find materials or “pure” varieties with higher yields, resistance to biotic and abiotic factors, and adaptation to local conditions, which make quinoa an economically profitable crop in the Boyacá department.
