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 with expedite the movement of tolerant germplasm into advanced breeding programs. Genotypes with improved vegetative and reproductive cold tolerance will be identified and the genetics underlying the tolerance will be determined. With the decline in the Ogallala Aquifer from continued withdrawal for agricultural production on the Great Plains, many locations are experiencing reduced well capacities. Water limitations prevent producers from realizing maximum yields, and new germplasm with enhanced yield potential and erect leaves are needed to optimize yield development for the available water. We will identify markers and genes associated with high seed number and erect leaf traits.
