Rice has been selected as one of the cereal species to be included in a bioregenerative life support system. Humans can consume the grains with minimum food processing without raising the blood sugar levels as with wheat or potato starch. Indica (long grain), japonica (short grain), tall, and semidwarf varieties of rice have been chosen from throughout the world. Greenhouse screens of 51 rice cultivars selected those with high harvest indices (edible/total biomass) and yields (g/m3/day) for hydroponic comparisons in growth chambers. Additional information, such the determination of an optimal photoperiod for flowering has been collected for nine of the cultivars considered for selection. Ongoing greenhouse comparisons for promising candidates include density studies to maximize yield on an area basis and alternative harvest scenarios (ratooning, harvesting as grains ripen).
