Upright and runner peanut genotypes were subjected to 27 days of water suspension, starting at vegetative phase and evaluated for their agronomical components and harvest index. The trail was carried out in a greenhouse using a completely randomized design, with factorial scheme 8 x 2 ( genotypes x treatment), with five repetitions. The following variables were analysed: dry weight of the plant, dry weight of roots, main stem height, pods plant(-1), harvest index and index of tolerance to drought. It was found that upright genotypes had better physiological adjustment when submitted to prolonged water stress, among them genotype 55 437 was more tolerant. All runner genotypes were sensitive to water stress, however LViPE-06 was less sensitive revealing as a promising material for the generation of divergent population.
