Jackfruit was successfully micropropagated using axillary buds as explant from mature tree on modified MS medium supplemented with 18 mg/litre BA in combination with 0.2 mg/litre IBA. Highest number (4–5) of usable shoots were developed after 4 subcultures on medium supplemented with 2 mg/litre BA and 0.2 mg/litre IBA. Higher concentration of BA in shoot proliferation medium produced increased number of adventitious shoots. In-vitro grown microshoots rooted in half-strength MS medium containing 1.0 mg/litre IBA with 58/7% rooting frequency. Rooted shootlets were subjected to hardening treatments and they readily established (80%) in sterilized mixture of sand, soil and farmyard manure.
