Crop selection for advanced life support systems in the ESA MELiSSA program: Durum wheat (Triticum turgidum var durum)

As part of an ESA MELiSSA investigation into advanced life support (ALS) candidate crop cultivar selection and growth requirements, the University of Guelph's Controlled Environment Systems Research Facility (CESRF) conducted a case study on growth and development of four durum wheat cultivars (Triticum turgidum var durum) grown hydroponically under controlled conditions in a sealed environment. Cultivars tested were Canadian developed Avonlea, Commander, Eurostar and Strongfield. There were few fundamental differences in durum quality parameters between hydroponically and field grown wheat, however yields of Eurostar and Strongfield exceeded those of field trials by 41% and 87% respectively.
