Developing inoculants with these PGPRs requires a rigorous selection of highly effective native bacterial isolates. In the present study, 29 bacterial isolates were obtained from the rhizosphere of \u2018Zutano\u2019 avocado (\n                    <jats:italic>Persea americana<\/jats:italic>\n                    Mill.), a rootstock widely used for the commercial cultivar \u2018Hass\u2019, from a commercial orchard on the northern coast of Peru.
