Chickpea (Cicer arietinum L.) is a leguminous of wide acceptance in Cuba; it constitutes tolerant specie to adverse environmental conditions, besides their nutritional contribution. Rizobia, which habit inside the chickpea nodules, contribute with benefits to the plant that is why they could be used to elevate their yields and to extend the crop in the country. The objective of this study was to obtain isolates of possible rizobia associated with different chickpea varieties and soil types in Cuba, as well as to characterize them in terms of their tolerance to different pH and temperature values. From seven chickpea varieties sowed in four soil types, 63 bacterial isolates were purified. From them, 11 isolates as possible rizobios by their morphophysiologic and biochemical characteristics were selected. Three of these isolated stood out by tolerate acids and basic pH values and high temperatures, so they could be promissory to constitute active ingredients of new inoculants for this vegetable specie.

Palabras clave : leguminous; growth; selection.
