ABSTRACT

The investigation was carried out at the College of Horticulture, Bidar to study the “Performance of grafts of different scion varieties on the different rootstock of mango (Mangifera indica L.) under nursery conditions” with thirty-six treatments comprising of twelve rootstocks (Kurukkan, Kitchner, Olour, EC-95862, Kensington, Peach, Nekkare, Muvandan, Bappakai, Mylepelian, Starch and Local) and three scions (Baneshan, Dashehari and Kesar). Among different rootstocks, Nekkare registered minimum days for sprouting, maximum sprout length, graft success, the height of grafted plant and number of leaves per graft (12.47 days, 6.08 cm, 89.17%, 29.4 cm and 18.33 respectively) whereas the maximum scion girth and root-collar diameter was registered with Bappakai (5.67 and 6.57mm respectively). In scion varieties Kesar recorded minimum days for the emergence of sprouts (15.92 days), maximum sprout length (5.39 cm), graft success (85.83 %), the height of grafted plant (26.74 cm), scion girth (5.55 mm) and root-collar diameter (6.51mm). In the case of different rootstock scion combinations, Nekkare grafted with Kesar recorded a minimum number of days taken for sprouting (11.4 days), maximum sprout length (7.15 cm), graft success (95 %), the height of grafted plant (33.55 cm) and several leaves per graft (19.7) whereas, scion girth and root-collar diameter were found non-significant.
