| Resumo: | Peas are nutritionally important for humans and animals. Ecologically and economically its valueraises from the ability to fix nitrogen symbiotically. Due to failures in nodulation under field conditions, a programof isolation and selection of rhizobia for peas was carried out to establish future recommendations for inoculantproduction. Three experiments were carried out and a total of 175 new isolations were tested under controlledconditions, using sand + vermiculite (2:1) and nutrient solution. In two officially recommended strains (SEMIA3007 and SEMIA 3012) inefficiencies were detected, but it was possible to recover the efficiency of the strain SEMIA3007. This study showed the existence of potentially infective strains but not efficient in nitrogen fixation suchas EEL 5501. According to the selection stage achieved in this study, the strains recommended to continue in theselection program in soil and field conditions are: EEL 2301, 2901, 3001, 5501, 3301, 3302, 6502, 6802, 7802 and 13402. |
