In Veracruz, terminal drought is the most limiting abiotic feature for the production of beans (Phaseolus vulgaris L.) in the production system of residual moisture. The objectives of the research were: to rated opaque Negro bean genotypes for resistance to drought and to identify the most efficient yield under irrigated and terminal drought in winter-spring 2013, two experiments were conducted Cotaxtla, Vieracruz; one with full irrigation and other irrigation suspension from the start of flowering. 22 lines and varieties Negro INIFAP, Negro Tacaná and Negro Jamapa were evaluated in randomized block experimental design with three replications. Days at physiological maturity were quantified, dry matter production without grain, pods per plant, seeds per pod, 100 seed weight and grain yield. As estimators of efficiency indices drought susceptibility (ISS) and relative efficiency yield (IER) were used. Yield and the number of pods per plant were the most affected characteristics by terminal drought, with average reductions of 41.39 and , NCB-229, SCN-2, Jamapa Plus and SEN-70 were the most resistant genotypes to drought, whereas X02-33-159-2, X02-33-147-2, B 98311, MBSF-14729 and Negro Jamapa, the most susceptible. CIAT-103-25, SCN 2 SEN 70, NGO 229, 17-99 and NCB 229 showed the best efficiency in irrigation and drought yield (IER greater than 1.35) while X02-33-159-2, B-98311, MBSF-14729 and Negro Jamapa, had the lowest production efficiency.
