Nodulation ability and effectiveness of native rhizobia from the seven districts of Uttarakhand in French bean was determined. Total of 50 rhizobial isolates separated from the nodules were evaluated for their ability to form nodules and effectiveness under net house and glass house conditions. These isolates exhibited typical characteristics of Rhizobium sp. on yeast extract mannitol agar media supplemented with Congo red. Out of fifty isolates 36 were authenticated as Rhizobium based on their ability to nodulate French bean. French bean inoculation with the rhizobial isolates significantly increased the dry shoot, root and total biomass; and shoot: root ratio. The dry shoot, root and total biomass produced due to inoculation with rhizobial isolate RA6 was highest among all the rhizobial isolates. The dry shoot biomass produced due to inoculation with rhizobial isolates RA6, RL21 and RA8 was statistically at par with that of reference strain MTCC 10096. The inoculation of French bean with rhizobial isolate RA6 produced total dry biomass significantly higher by 154.4 per cent over reference strain i.e. MTCC 10096.Our results demonstrated the presence of native rhizobia in soils of N-W Himalayas capable of nodulating French bean that are either superior or at par with reference strain in improving the overall growth and synthesis of higher biomass in French bean.
