Investigations were carried out to study the plant growth promotional ability of native pink pigmented facultative methylotrophs (PPFMs) of major chilli (Capsicum annuum L.) growing areas of North Karnataka. Selected isolates were screened for beneficial characters like production of phytohormones, phosphate solubilisation and siderophore production. Highest indole 3 acetic acid and gibberellic acid production was recorded in PPFM6, 19.77 and 128.28 ïÂÂg/ml of culture filtrate, respectively. The strain PPFM170 recorded highest cytokinin production (2.54 ïÂÂg/ml). Mineral phosphate solubilisation index was in the range of 0.31 to 0.97 and the isolate PPFM6 produced higher amount of inorganic phosphorous at 5 days after incubation (6.5%) and even at 10 days after incubation (8.99 %). The production of catechol type of siderophores was observed among PPFM isolates which ranged from 0.2 to 0.61 µmoles of Di Hydroxy Benzoic Acid. The present study has identified potential native PPFM strains from major chilli growing districts of North Karnataka for their exploration in improving production and productivity of chilli.
