Studies were conducted to know varietal response on plantlet regeneration through macro- propagation in banana. Many varieties and cultivars were grown in different regions of country and there is a need to know which variety will respond well to macro-propagation. Three commercially cultivated varieties were taken for experiment viz., Ney Poovan, Rajapuri and Grand Naine. Major problem in cultivation of banana is supply of quality planting material. In-vitro propagation is tried, but is not easily affordable by normal farmer/ gardener and the same time traditional production (in field) of planting material will not be sufficient. Hence, macro-propagation was tried to see the practicability in using it for large scale multiplication which falls in between traditional and tissue culture method of propagation. Banana has strong apical dominance, which when suppressed will give rise to many side suckers. This principle was used in macro-propagation. Different varieties/cultivars were used to know the regeneration capacity of corm through macro-propagation. Among different varieties/cultivars used Grand Naine has produced significantly higher number of primary buds per corm, number of plantlets after secondary decapitation, total number of plantlets per corm and days taken for first bud emergence.
