A Survey of Abiotic Stress Tolerance Variability in Cotton Germplasm

Improved tolerance to abiotic stress is important for the sustainability of U.S. cotton agriculture. Are goals are: 1) Identify genotypes with contrasting stress tolerance phenotypes by screening a wide range of cotton germplasm for physiological, morphological and phenological responses to water deficit and thermal stress, and 2) Initiate the creation of breeding populations segregating for abiotic stress tolerance.
