One of the objectives of the soybean physiology-breeding program at Nebraska is the evaluation of various procedures used for measuring the response of soybeans to heat and drought stress . We are primarily interested in techniques amenable to large-scale screening of soybean populations or germplasm, so that heat or drought tolerant genotypes can be identified and used in our breeding program. Consequently, the important considerations are rapidity in sampling, simplicity in equipment and procedural requirements, and detection of genotypic (rather than environmental) differences.
