Abstract

The most common method of propagating jackfruit is by seed, yet vegetative propagation techniques arelabor-intensive and seasonal, and plantlets cultivated from seeds are heterozygous and do not conform totype. Hence, micropropagation can be used to overcome the limitations of conventional vegetative propagationmethods. A better culture establishment was obtained with shoot tips cultured on MS medium with2 mg L-1BA. On MS media treated with BA (1-4 mg L-1) and 0.35 mg L-1 GA3, shoots proliferate. Thehighest number of shoots were obtained in MS medium supplemented with 3mg L-1BA and 0.35 mg L-1GA3and the highest shoot length and maximum number of leaves were recorded in MS medium supplementedwith 2.5 mg L-1BA and 0.35 mg L-1GA3. These proliferating shoots failed to yield any roots. Therefore, thiscould be a possible future career path.
