The present study was undertaken to obtain cultlvar and area specific rhizobia for pea. Soil samples were collected and analysed for soil characteristics. Six isolates LC1 to LC6 of Rhizobium Isolated from 3 different varieties grown in soils of Ludhlana belt were screened and tested for legume-Rhizobium symbiosis along with a reference culture with three varieties of pea at Ludhiana. In general, reference culture (P-4) was found better for most of the symbiotic parameters with variety Arkel and MA-6. However, for Pb-88, Isolate LC-2 interacted best for nodule weight, nitrogenase activity and LC-4 for remaining parameters. LC-5 x Arkel, LC-4 x MA-6 and LC-2 x Pb-88 were the best combinations for grain yield.
