Abstract

The selection of tolerant varieties of bean to the drought can constitute a strategy that permit minimizing the effect of the hydric deficit on the yield and the quality of the bean grain. The objective of work was to identify more tolerant varieties to the drought, at the farmstead Sabanilla of her CCS "Sabino Pupo", Unión de Reyes. The morphologic characteristic and common bean indicators of yield of eight varieties (CC 25-9 R, BAT 58, Güira 89, CC 25-9 white, CC 25-9 black, Tomeguín, Velazco Largo and BAT 304) were evaluated, in different conditions: four irrigations (drought) and ten irrigations (optimal conditions of humidity). With the results of reproductive index (IR), sensibility index to drought (ISS) and the percentage of losses of the yield (PR) allowed bring to a following conclusion: the varieties more tolerant behavior in the conditions of experimentation where: Tomeguín, BAT 304 and CC 25-9 R and the more susceptible: Velazco Largo and y CC 25-9 black.
