Selected lines were grown under varying patterns and degrees of drought stress under rainfed conditions at Yoakum and other South-Central Texas sites in different years. Entries were compared for pod yield, pod and kernel traits, leaf relative water content, leaf porometer data, water potential via hydraulic leaf press, soil water extraction patterns, foliar temperatures, and differences in plant measurements with varied degrees of intra-row competition. The effects of accumulated water stress as indicated by daily leaf temperature measurements on pod yields and quality were quantified in a standard cultivar over a three-year period. Forty-eight selected peanut lines were studied in three crop years for reaction to varied water levels supplied by a source line irrigation system
