“…Recently, multi-location experiments (MTE) became valuable to assess quinoa genotype adaptation in new regions [ 9 , 22 , 23 ]. According to Gadisa et al [ 20 ], it is difficult to identify consistently superior genotypes across environments when genotype x environment interactions (GEI) are highly significant.…”

“…Several statistical analyses are used to evaluate the yield performance of genotypes across the environments such as the regression coefficient of the GEI effects on the environmental [ 13 ], the coefficient of variation (CV) [ 14 ], the non-parametric stability [ 15 ], the harmonic mean of the genotype relative performance value [ 16 ], and the AMMI—Additive Main effects and Multiplicative Interaction model [ 17 ]. There are different crops that benefit from these approaches, including corn [ 18 ], rice [ 19 ], bread wheat [ 20 ], maize [ 21 ], and quinoa [ 22 , 23 ]. AMMI analysis allowed us to analyze the GEI effects in multi-location trials.…”

Chenopodium quinoa is a pseudocereal species identified as a potential crop to mitigate world food security. It has the ability to adapt to diverse agro-ecosystems ranging from sea level to over 4000 masl. Its cultivation in Morocco began in 1999, as it is tolerance to drought, salinity, and frost, and it can grow on marginal soils. It has exceptional nutritional value, as it is rich in proteins, essential amino acids, mineral nutrients, trace elements, vitamins, and unsaturated fatty acids. The present study aims to evaluate the adaptation of 14 quinoa varieties and lines from four different origins through fourteen agro-morphological characters. The experimental trials were conducted at five contrasted agro-climatic sites across the central part of Morocco. The data analysis showed high variability among the tested varieties and between sites for all assessed traits. The Meknes (foot-hill plain) site was the most productive; its grain yield reached 78.6 qx/ha. At the Rabat (coastal land) and Berrechid (continental plain) sites, grain production was respectively 56.4 and 45.9 qx/ha. The SW2 Moroccan line produced the highest grain yield that reached 78.3 qx/ha across sites. The Danish variety Titicaca presented the best harvest index (HI = 0.69) as well as the best “thousand kernel weight” (TGW = 3.4 g). As the mildew infection evaluation, the Vikinga and Titicaca varieties ranked the most sensitive to Peronospora farinosa. The germination rates of the harvested seeds were prejudiced by the sites’ high temperatures and were low in Tinejdad (oases site) and El Kbab (mountain plateau). The best average germination rate across sites was that of the Puno variety (84.5%). According to the Additive Main effects and Multiplicative Interaction analysis (AMMI), 23% of the grain yield variability is due to the genotype, while 32% is due to the site by the variety interaction contribution to the production variability. AMMI analysis also ranked the varieties according to their productivity and stability value. Accordingly, two varieties that have yielded above the overall average (42.7 qx/ha) are considered stable; those are Riobamba and W11, which is a local selected line. Titicaca, ILLPA, Atlas cultivars and the SW2 local line presented the best grain yield in one of the experimental sites but performed not as well on the others.

“…Scales for measuring the farmers' preferences were given values from lowest (1) to highest (5). To identify the major constraints associated with quinoa production, rank index 1 was employed (Vasconcelos et al, 2019).…”

“…It is rich in proteins, fats, dietary fiber, vitamins and minerals, with an extraordinary balance of essential amino acids (Park et al, 2017). In general, the nutritional characteristics of the crop, combined with its adaptation to a wide range of growing areas, make it very promising for the future of Ethiopia, particularly in areas where there is malnutrition and recurrent drought (Vasconcelos et al, 2019). At the same time, it is comparable in energy content to the major crops that are vital in Ethiopia's food system.…”

A household survey was conducted to assess the cultivation of quinoa in Wag-himira zone, Ethiopia. Farmers' perceptions of quinoa, its profitability, and relevant production practices and constraints, as well as their acceptance of the crop and willingness to grow it, were profiled. A total of 247 farmers were purposively sampled based on their involvement in quinoa farming for at least one year. Data were collected using a semi-structured questionnaire, then analyzed using descriptive statistics, a cost-benefit analysis, a Likert rating scale and a ranking index. The results reveal that except for poor resistance to insect pests and marketability, farmers had a good perception of quinoa according to most preference parameters. It had a higher grain yield than teff, but had lower grain and straw yields than other competing crops. The gross margin was higher than for other crops, and quinoa was ranked third according to its benefit-cost ratio, behind sorghum and faba beans. The farmers' sensory preferences for quinoa food types were injera, bread, kitta and porridge in descending order. Among the respondents, 67.6% were interested in continuing with quinoa production, but the rest refused due to labor shortages, market problems, seed shortages and food recipe knowledge gaps. Susceptibility to pests, marketing and straw palatability problems and the requirement for fertile soil were constraints on quinoa production. Therefore, concerned bodies such as research institutes should pay attention to developing and/or devising appropriate pest control mechanisms. Seed-producing and marketing cooperatives should be strengthened to make quinoa crop production viable.
