Abstract
Jamun is propagated by seeds as well as vegetatively and the grafts raised on seedling rootstocks of unknown source resulting in variation among the plants. Hence, there is a need to identify the suitable rootstock for propagating jamun to get maximum graft success. The time of grafting is the most important factor for highest graft success and influenced by the climatic conditions prevailing in particular season in addition to the type of rootstocks. Considering the above factors the research was carried out at Kittur Rani Channamma College of Horticulture, Arabhavi during 2018-2019 to study suitable season and rootstock for the jamun variety AJG-85, which is more popular variety in and around Belgaum district. Jamun variety AJG-85 grafted on its own rootstock during October recorded the maximum number of sprouts (3.92, 4.49 and 4.56 respectively), sprout length (7.91, 16.18 and 22.20 cm respectively), per cent graft success (79.39, 88.80 and 90.94% respectively), per cent graft survival (93.96 and 89.30% respectively) at different days after grafting and minimum number of days taken for sprouting (19.15).
