Four levels of production inputs were used over a four-year period to create stress and non-stress environments for pod production of five peanut (Arachis hypogaea L.) genotypes. Analyses were computed for genetic and phenotypic variability, stability, modified stability and profitability. Sufficient phenotypic and genetic variation existed for selection of productive genotypes in both stress and non-stress environments. The experimental line UF 67 was the most productive in stress environments and, under the conditions of this experiment, was also one of the most profitable. The greatest minimum net economic benefit came from growing UF 67 in stress environments. The cultivar Florunner was the most productive and the most profitable line when grown under non-stress environments. The additional information generated from modified stability analysis and economic analysis can be beneficial to plant breeders interested in developing productive lines for stress environments.
