“…However, as a food and as a crop, quinoa still has a series of limitations, such as increasing yield potential, improving tolerance to some abiotic stress conditions, identifying genotypes that are tolerant to crop‐limiting phytosanitary problems, and generating varieties with low saponin levels in the seeds to obtain sweet genotypes (Opazo‐Navarrete et al., 2018; Suárez‐Estrella et al., 2018), which is highly required in the commercialization of this food. Thus, it could be expected that these are the topics to be addressed in quinoa breeding programs in the short and medium term (Coronado et al., 2022; Manjarres‐Hernández & Morillo‐Coronado, 2022).…”

Currently, the demand for healthy consumption and the use of alternatives to dairy proteins for the development of foods with good nutritional value are growing. Quinoa has received much attention because it contains a high content of proteins, essential amino acids, essential fatty acids, minerals, vitamins, dietary fibers, and bioactive compounds. Nevertheless, this content and the bioavailability of specific compounds of interest are related to the genotype, the agri‐environmental conditions, and management practices where quinoa is grown and postharvest management. This article aimed to analyze the research trends for three knowledge areas: quinoa plant breeding for nutraceutical properties, plant–soil relations focused on abiotic stresses, and postharvest and value‐added transformation activities. To this end, a specific methodological design based on bibliometrics and scientometrics methods was used. Through these analyses based on publications' keywords, titles, abstracts, and conclusions sections, for each knowledge area, the key research trends (scope and main topics), the classification of trends based on their development and relevance degree, and the core of knowledge were established. The trends comprise the current state of research. Finally, analyzing the conclusions, recommendations, and future research sections of key publications, a strong correlation among plant breeding research to obtain varieties with tolerance to biotic and abiotic stresses, nutritional and functional compounds of interest for food safety, and the development of products with higher added value established interest in further research on the potential bioactivity of quinoa and the verification of health benefits to humans.

Chenopodium quinoa is an Andean species of great interest because of its excellent nutritional quality and great adaptability to different environmental conditions. In addition, the high phenotypic diversity has caused difficulties in the correct taxonomic identification, and there are few studies on the phylogenetic relationships of quinoa in Colombia. Therefore, the objective of this research was to determine the phylogenetic relationships of quinoa with the matK and rcbL chloroplastid genes to characterize the genetic diversity in Colombian quinoa. Evolutionary analyses were performed using nucleotide substitution rates, pattern, base composition, and phylogeny construction. The rbcL gene presented approximately 1344 bp, and matK had 646 bp, which were translated into 434 and 215 amino acids, respectively. The nucleotide composition of the genes showed high percentages of similarity and identity with the Chenopodium quinoa sequences registered in GenBank and BOLD. Similar phylogenetic trees were obtained with the rbcL and matK genes, and both concatenated sequences grouped the accessions into clades. The results showed that Colombian quinoa has low rates of genetic differentiation that may be due to the domestication processes of the species, the lack of certified seeds, and the constant exchange of seeds between farmers in the principal producing areas of the Andean region.

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 analysis 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.
