Abstract From several native clover species, growing in six different soil types, 170 Rhizobium leguminosarum biovar trifolii strains were isolated, covering the central and southern regions of Portugal. The effectiveness of the strains varied from ineffective to highly effective on T. subterraneum cv. Clare and on T. fragiferum cv. Palestine, with a predominance of medium and high effectiveness on both host plants. The effectiveness was not influenced by provenence (soil or plant), except for the strains from the rankers soils and for the strains isolated from T. pratense, that were ineffective or medium effective on T. subterraneum. Selected strains were evaluated for effectiveness on T. subterraneum cv. Clare, using the commercial strain TA1 as reference. Several of the isolated strains were more effective than TA1, indicating that local strains may be used to produce better inoculants.
