Abstract:

In order to study the effects of plateau environment on the nutritional components of quinoa, the main nutritional components of 8 quinoa varieties (lines) from Wulan County and Delingha City (3000 m, high altitude arid area) in Qaidam Basin in western Qinghai and Datong County (2300 m, high altitude semi-arid area) in eastern Qinghai were determined and analyzed by AMMI model. The results show that: (1) the content of crude fiber, protein, β-glucan, carbohydrate and α-vitamin E are greatly affected by environmental factors, and the total sugar content is affected by both variety and environmental factors, the interaction of variety and environment has a significant effect on the crude fiber content; (2) there are differences in the stability of nutrient components of quinoa varieties (lines). In the cultivation of quinoa on plateau, the environmental advantages should be taken into full consideration, the genotype and environment interaction should be highlighted, and the suitable varieties should be selected according to local conditions.

Key words: Chenopodium quinoa, nutritional components, variety factor, environmental factor, AMMI model
