Background: Mango is a highly cross-pollinated and allopolyploid in nature. It is mandatory to keep such fruit plants trueto-type through asexual techniques. The experiment was needed on variety and rootstock age on the success and survivability of epicotyl grafting in mango. Epicotyls grafting in mango has been successfully used as an efficient, economic and rapid method for propagation of mango. Objectives: This experiment was conducted to study the effect of different varieties and rootstock age on the success and survivability of epicotyl grafting in Mango plant. Method and Materials: The experiment consisted of three varieties viz., Kachametha, Mollika and Langra and four ages of rootstock viz., 10, 20, 30 and 40 days aged. The experiment was conducted in Randomized complete Block Design (RCBD). Results: The time required to bud break and first flash, rootstock length, rootstock diameter, scion length, scion diameter, stionic height, number of new leaves per graft, percentage of graft success and survivability were significantly influenced by varieties and age of rootstock. In case of variety, Mollika took minimum time (16.32 days) for bud breaking and first flashing (25.40 days). In addition, Mollika variety showed best performace in respect of rootstock length (20.60 cm), scion length (19.05 cm), stionic height (39.24 cm) and number of new leaves per graft (17.34) at 150 DAG. The highest graft success (83.67%) and survivability (75.42%) was also observed in Mollika variety. On the other hand, 30 days aged rootstock took minimum time (15.78 days) to bud break and first flash (25.58 days). Moreover, the highest rootstock length (25.06 cm), scion length (20.47 cm), stionic height (44.98 cm), number of new leaves (19.62) per graft were noted from same aged rootstock. Rootstock of 30 days old aged gave the highest graft success (81.56%) and survivability (65.22%) at 150 DAG.
