In-vitro androgenic haploids in Musa. balbisiana L cv. bhimkol were produced by anther culture at uninucleate stage of pollen. Young 30 day’s old immature male flowers with 5 stamens obtained by cutting out the bracts in between 20th to 30th were used as explants for induction of callus. The best medium for inducing callus from anthers were found to be MS (Murashige and Skoog) basal medium supplemented with 6-BAP (1.0 mgL-1) and IAA (Indole-3- acetic acid 2 mg/l.) with a frequency of 27.33±2.52 while best media for regeneration of shoots from callus was found to be MS medium supplemented with 7mg/l 6-BAP, 0.5mg/l IAA, 350 mg/l CH. Regenerated shoots were isolated and inoculated on MS medium supplemented with four different concentrations (0.25, 0.5, 1.0 and 2.0 mg/l) of IBA to induce root. IBA at a concentration of 1.0 mg/l produced best rooting. In our study out of 350 anthers inoculated only 12 plants were regenerated from anther callus and embryogenesis, all the plants were transferred and established in the potting mixture containing soil, vermicompost and farm yard manure in the ratio of 1:1:2. Using direct method of chromosome counting 58.33 % plants were found to be haploids and 41.66 % plants were diploids. This is the first report on the production of haploid plants in cv. bhimkol However, diploids banana plants were also found.
