This study was carried out within the areas from “José Castellanos” Strengthened Credit and Service Cooperative (SCSC), located in Santa Cruz del Norte municipality, with the aim of evaluating the agronomic response of 12 common bean cultivars, introduced into the collection of Local Agricultural Innovation Program (LAIP), which is developed at the National Institute of Agricultural Sciences (INCA), in order to diversify the present germplasm. The study arose from the need of having better crop cultivars to replace the existing ones, regarding their response to the specific conditions of each country area. Sowing was performed in the second half of January 2009, including the pre-commercial cultivars Santiago-3 (S-3) and Hg-8 (Holguín-8), preserved at LAIP work collection. Both sowing and cultural practices followed the guidelines established by technical instructions. Among other results, it was generally observed that the cultivars under study showed significant differences (p≤0.05) in pod number per plant (PNP), grain number per pod (GNP), 100-grain weight (100GW) and yields in kg ha^-1. Grain length and width had distinct responses between cultivars; therefore, these traits can be used to characterize bean germplasm. After a complete analysis of results, Hg-8, R-5, R-11, R-6 and R-4 cultivars were highlighted for their best agronomic response in the evaluated group
