In Cuba, the chickpea is a very appreciated grain in the population's diet because of its high nutritional value, but there are only nine varieties in the national market, so it is necessary to increase the varietal diversity of this species that also allows to substitute imports in a sustainable manner. The study was developed in the National Institute of Agricultural Sciences (INCA) with the purpose of evaluating the behavior of 10 promising chickpea-type Kabuli genotypes, selected from germoplasm introduced from the International Center for Agricultural Research in the Dry Areas (ICARDA) from Syria and the National Institute of Agricultural Technology (INTA), Argentina. Seven quantitative morphoagronomic variables were evaluated: plant height (AP), height of the first pod (AV), number of primary basal branches (NR), number of pods per plant (NV), number of seeds per plant (NS), empty pods (VV) andperforated pods (VH) and the data were analyzed by univariate and multivariate methods of principal components for the set of variables and genotypes and by cluster analysis between genotypes. The results showed that the variability in the studied collection was represented mainly by AV, AP and NS, the latter correlated negatively with the previous ones. A group consisting of six genotypes that showed stability in their morphoagronomic behavior under the conditions of the study was detected, so it is recommended the evaluation of these in superior yields trials.

Se evaluaron siete variables morfoagronómicas cuantitativas: altura de la planta (AP), altura de la primera vaina (AV), número de ramas basales primarias (NR), número de vainas por planta (NV), número de semillas por planta (NS), vaneo de las vainas (VV) y vainas horadadas (
