The heat resistant strain HR-12 of Rhizobium sp. (Cajanus) was found to be symbiotically superior strain when tested on pigeonpea plants under field conditions in three successive kharif seasons (2004 to 2006). Most of the symbiotic parameters viz; root and shoot dry weight, per cent and total shoot nitrogen and grain yield in pigeonpea plants inoculated with HR-12 showed significantly higher values than the plants inoculated with the wild type (WT) strains PP201 (parent) and PP1021.
