Elucidating the diversity of the super crop quinoa
― Expectations for breeding quinoa with high environmental adaptability and excellent nutritional properties ―

JIRCAS, in collaboration with Kyoto University, RIKEN, Tottori University and Actree Corporation, has created a collection of pure quinoa lines that originated from South America and cultivated around the world, revealing the diversity of the super crop quinoa. Each quinoa line was characterized in terms of seed weight, height and stem diameter, and strains suitable for cultivation in temperate regions around the world including Japan were identified. Some lines were also found to germinate in saline water with the same level of salt content as seawater. The results of this research have paved the way to elucidate the molecular mechanisms underlying the high environmental adaptability and superior nutritional characteristics of quinoa. In addition, this research is expected to accelerate the breeding of super crop quinoa varieties with excellent nutritional characteristics and adaptability to severe environments, such as droughts, not only in South American countries such as Bolivia, where it originated, but also in more than 100 countries around the world where quinoa cultivation is spreading, thereby contributing to global food security, improving nutrition, and eradicating hunger (SDGs target 2: Zero Hunger).
