End Date: Sep 30, 2013
Our newly developed high throughput screening tools will provide, for the first time, a quantitative measure of the levels of pre- and post-flowering drought tolerance in germplasm collections, mutant populations, and hybrid combinations. This information will expedite the movement of tolerant germplasm into advanced breeding programs. Modification of plant architecture will be evaluated to determine morphologies that enhance yield with less water consumption. Genotypes with improved vegetative and reproductive heat tolerance will be identified, and the genetics underlying the tolerance will be determined. We will develop an irrigation management that optimizes the seasonal distribution of limited water to maximize grain yields of pre-flowering drought tolerant sorghum lines.
