Screen ~200 accessions of core and mini core rice accessions adapted to arid areas. Characterize yield, relative growth rate and characteristics associated with drought tolerance and water use efficiency. A portion of the accessions that will be tested are part of the U.S. National Plant Germplasm System (NPGS) collection while others are part of new collections from outside the U.S. This work will be done at the Limited Irrigation Research Farm (LIRF) in Greeley, Colorado. LIRF offers a uniquely instrumented facility to conduct research that requires good control of available plant water and monitoring of plant water use to better understand plant traits and whole plant strategies related to drought tolerance. We will specifically include belowground measurements of plant growth, morphology and physiology in addition to shoot and whole plant measurements. These traits from field experiments will be correlated to laboratory measurements of root growth.
