Cicer canariense is endemic to La Palma and Tenerife islands. Characterization of the bacteria nodulatingthis legume in soils of Caldera de Taburiente National Park and two locations in the northwest andsouth of the Park showed that C. canariense is a promiscuous legume nodulated by rhizobia genetic andphylogenetically diverse. These rhizobia belong to nine genomic groups which correspond to speciesor genospecies of genus Mesorhizobium. Some species have a wide area of distribution inside and outsidethe Park, while others were detected exclusively or predominantly in one location. The genospecies called M. tianshanense-subgroup, and M. caraganae-I and M. caraganae-II were majority and they couldconstitute new species of the genus. Some minority lineages are also new species. It was found associated with these mesorhizobia three distant symbiotic lineages, representing different symbiovars (sv.):sv. loti (characteristic of the Lotus-rhizobia.), sv. ciceri (characteristic of C. arietinum rhizobia) and anovel symbiovar specific to C. canariense. The sv. loti is the most widely distributed among the rhizobialgenospecies nodulating C. canariense. The evaluation of the symbiotic effectiveness with strains fromdifferent chromosomal background (different genospecies) and symbiovars showed large variabilityin the plant development. In general, sv. loti strains produced the best growth of plants, although theefficacy varied depending on the chromosomal background. Mesorhizobium tamadayense sv. loti strainswere the most effective.
