Farmers who grow beans (Phaseolus vulgaris L.) under rainfed conditions require early varieties producing grain tolerant to darkening and greater size in relation to Pinto Saltillo, which is the most popular variety in Durango. The objective was to obtain a bean variety than Pinto Saltillo in earliness, grain size and commercial quality. The Pinto Centennial (PT08034) was generated with the pedigree method, from the cross between Pinto and Pinto Mestizo Saltillo [(Pinto Mestizo / Pinto Saltillo) -7 to 5]. Pinto Centennial showed a yield (1 242 kg ha^-1) statistically similar to Pinto Saltillo (1 201 kg ha^-1), was found early maturity (89 vs 92 days) and 100 seed weight was significantly higher (35 g vs 30 g) with an interval between 26 and 45 g/100 seeds. The growth habit of Pinto Centennial is of an indeterminate vine with short non-climbing guides, the canopy has an average height of 27 cm and a growing guide of 75 cm. The transverse and longitudinal form of the Pinto Centennial seed is elliptical and the seed coat is cream-colored, pinto brown and a yellow hilum. Under field conditions, the Pinto Centennial plant showed tolerance to diseases such as anthracnose and rust, as well as intermediate susceptibility to common blight and root rot. Pinto Centennial was included in validation programs in the highlands of Mexico to establish its possibilities of adoption, adaptability and potential to increase yield and quality of beans produced in the region.
