Abstract
Jackfruit is traditionally propagated by seeds which creates variability in the seedling population as it is highly cross pollinated crop. Hence, to maintain genetic purity and also to propagate at commercial scale, vegetative propagation is the only viable option in this cross-pollinated crop. Therefore, the experiment was conducted to standardize the grafting methods and time of grafting in jackfruit. Wedge grafting during December–January had maximum survivability (92.40–93.60%) with par result in side grafting done during December–January (88.40–89.40%); however, it was decreased drastically thereafter (February–March) in all the grafting methods. Increment of sapling height was also measured maximum in wedge and side grafting, done during December–January. Maximum number of sprout graft−1 (6.30–6.70) was recorded in wedge and side grafting done during December–January; however, they were decreased gradually thereafter. Earliest leaf opening was observed in side grafting on 19th February (39.56 DAG) with par result in wedge grafting on 19th February (40.37 DAG) and side and wedge grafting on 4th February (40.02 and 40.18 DAG, respectively). Further, higher number of leaves graft−1 (16.72–26.31) along with bigger leaf length (8.96–10.20 cm) and leaf breadth (5.12–6.12 cm) was also recorded in wedge and side grafting done during December–January. The physiological attributes of the grafted saplings were also estimated significantly higher in wedge and side grafting, done during December–January. Hence, wedge and side grafting during December–January can be recommended for mass multiplication as well as maintain the traditional high yielding local genotypes of jackfruit.
