Abstract
The present investigation entitled ‘Studies on macropropagation in different local cultivars in banana was carried out during 2014-2015 at the Department of Fruit Science, Kittur Rani Channamma College of Horticulture, Arabhavi.
The influence of growth chemicals and bio-agents on production of quality planting material of banana cv. Ney Poovan (Musa AB) was found to be better with growth regulator treatment with BAP at 40 ppm (T2). Which found highest values for most of the parameters under study, such as, number of primary buds per corm (3.60), number of plantlets after second decapitation (13.46), total number of plantlets per corm (17.06), number of days taken for first bud emergence (29.06 days) and number of days for second decapitation (48.06). Bioagents such as VAM and Trichoderma viridae also showed best result in all root parameters.
Various growing media were used to find out the effect on plantlet regeneration in banana. Among different media used Sawdust in combination with FYM showed significantly best result compared to other media and showed best results in terms of number of buds per corm (3.80), number of plantlets after secondary decapitation (17.07), total number of plantlets per corm (20.13), number of days taken for first bud emergence (26.46) and number of primary roots (17.50). Hence media combination of Sawdust + FYM found economical, easily available, and less strenuous while mixing and produces early and quality plantlets.
To know the varietal response to macro-propagation, different local cultivars were used for experiment. From the experiment it was found that cv. Ney Poovan given best results for all root parameters and early bud emergence. Cultivar Grand Naine, performed well for, number of primary buds per corm (3.74) and number of days taken for first bud emergence (34.71). Hence it is found that, to get maximum number of plantlets all are suitable in macropropagation however, when the quality parameters are considered Grand Naine found to be better through macropropagation.
