“…The effect of the environment on plant morphology and seed quality is undebatable. As described previously, the growing conditions during the year can significantly affect important quinoa traits, such as the yield [ 27 ], fiber content [ 19 ], protein and amino acid content [ 10 , 28 ], as well as metabolomic composition [ 29 , 30 ].…”

Quinoa displays huge genetic variability and adaptability to distinct climatic conditions. Quinoa seeds are a good source of nutrients; however, the overall nutritional composition and nutrient content is influenced by numerous factors. This study focused on the nutritional and morphologic evaluation of various quinoa genotypes grown in the Czech Republic. Significant differences between years were observed for morphological traits (plant height, inflorescence length, weight of thousand seeds). The weather conditions in the year 2018 were favorable for all the morphological traits. The protein content of quinoa accessions ranged between 13.44 and 20.01% and it was positively correlated to mauritianin. Total phenolic content varied greatly from year to year, while the antioxidant activity remained relatively stable. The most abundant phenolic compounds were the flavonoids miquelianin, rutin, and isoquercetin. Isoquercetin, quercetin, and N-feruoloyl octopamine showed the highest stability under variable weather conditions in the analyzed years. A total of six compounds were detected and quantified in quinoa for the first time. Most varieties performed well under Central European conditions and can be considered a good source of nutrients and bioactive compounds. These data can be used as a source of information for plant breeders aiming to improve the quality traits of quinoa.

“…Quinoa is gaining popularity because to its high nutritional content and adaptability to a variety of environments. 40 , 55 Because of its natural drought and salt resistance, quinoa has become a popular crop for barren, saline and dry areas. 56 Quinoa fruit is excellent in nutrition, with a high protein content, a balanced amino acid ratio, and a high level of dietary fiber, mineral elements, and vitamins.…”

“…It is appropriate for a wide range of people, particularly pregnant women, celiac disease sufferers, and diabetics. 55 , 57 Natural betalains is now obtained mostly from beetroot, and the need for betalains on the international market increases every year. 58 , 59 The presence of betalains enables quinoa to seem colorful, and the mature quinoa fruit is so colorful that 66 different colors of quinoa seeds have been observed in Bolivia’s quinoa harvesting area.…”

Betalains provide Chenopodium quinoa bright color, and the key enzyme genes for betalain biosynthesis include CYP76AD , DODA , and GTs . In this study, 59 CqCYP76AD , CqDODA and CqGTs genes in quinoa were identified and characterized by gene structural characteristics, phylogenetic relationships and gene expression patterns. The CqCYP76AD genes were divided into ɑ, β and γ types, CqDODA into ɑ and β types, and CqGTs into CqcDOPA5GT , CqB5GT and CqB6GT types according to phylogenetic relationships. The analysis of co-linearity identified eight pairs of duplicated genes which were subjected to purifying selection during evolution. CqCYP76AD and CqDODA , as well as CqcDOPA5GT and CqB5GT may have been evolutionarily linked in genetic inheritance, based on gene location and gene structure study. The tissue expression specificity of CqCYP76AD , CqDODA , and CqGTs genes in response to seed germination and cold stress was studied by RNA-Seq data. The genes CqCYP76AD , CqDODA , and CqGTs were involved in betalain biosynthesis and cold stress. CqCYP76AD , CqDODA , CqcDOPA5GT and CqB5GT gene sequences were consistent in the eight quinoa samples and showed significant variations in expression. In contrast, the inconsistency between changes in gene expression and betalain accumulation indicates that other factors may influence betalain biosynthesis in quinoa. This study offers the theoretical basis for the roles of the CqCYP76AD , CqDODA , and CqGTs genes in betalain biosynthesis and cold stress in quinoa, as well as a guide for the full utilization of betalains in quinoa plants.

“…Quinoa is originated from the Andean region of South America (Adolf et al, 2013). This crop has received much attention because of its high nutritional value and its high tolerance to frost, drought, and salinity (Jensen et al, 2000;Jacobsen, 2003;Jacobsen et al, 2005;Adolf et al, 2013;HlaśnáCepkováet al, 2022;Shafiq et al, 2022;Terletskaya et al, 2022). Besides the human consumption, quinoa could be used as a fodder crop of high quality in adverse environments (Liu et al, 2020).…”

Quinoa (Chenopodium quinoa Wild.) is a drought and salinity-tolerant crop that originated in the Andes over 7000 years ago. It is adapted to different agroecological areas and can be grown from sea level to an altitude of 4000 m. The outstanding nutritional status of quinoa, with its high content of proteins, vitamins, and minerals, makes it a promising crop able to combat hunger and malnutrition in different countries in the 21st century. Quinoa cultivation has expanded from South America to Africa, Europe, Asia, and North America. Reviewing quinoa cropping practices will provide farmers with adequate recommendations for improving the agronomic and environmental sustainability of quinoa cultivation worldwide. For this reason, we conducted a systematic review of agronomic management practices in 148 field experiments conducted worldwide from 2000 to 2022. The collected data from the literature were analyzed and presented by location to determine high-performing genotypes, optimal planting dates, and other adequate cropping practices affecting quinoa performance and yield. Results showed that quinoa could be successfully cultivated in the new farming areas. Quinoa yields were higher than those reported in its place of origin, ranging from 108 kg ha-1, obtained by KU-2 in Washington State, to 9667 kg ha-1, obtained by Longli in China. Although quinoa is considered a crop with low input requirements, positive grain yield response was observed following increasing fertilization rates. Quinoa needs 2 to 4.6 kg of nitrogen to produce 1q of grain yield. In terms of phosphorus and potassium, quinoa needs 3.7 kg P2O5 and 4.3 kg K2O to produce 1 ton of total biomass. Quinoa has low water requirements (300-400 mm). However, a positive response was recorded with water quantities up to 866 mm. During our investigation, weed control in quinoa crop is still undeveloped and usually done manually. Research addressing this issue can increase quinoa yields and decrease the production cost. Downey mildew and birds’ attack are the major phytosanitary problems affecting quinoa grain yield. Other pests such as miners and aphids can also affect the health of quinoa, but their injury is not a serious problem. After the harvest, saponins found in the out layer of the seed can be removed through washing and mechanical pearling process, but the latter technic was found to be efficient and cost effective to reduce the saponin content. Our results constitute the first recommendation base for the adequate worldwide agronomic practices of quinoa crop.
