Development of micropropagation protocol for jackfruit (Artocarpus heterophyllus Lam.) KJ 182.

The most common method of propagating jackfruit is by seed, yet vegetative propagation techniques are labor-intensive and seasonal, and plantlets cultivated from seeds are heterozygous and do not conform to type. Hence, micropropagation can be used to overcome the limitations of conventional vegetative propagation methods. A better culture establishment was obtained with shoot tips cultured on MS medium with 2 mg L-1 BA. On MS media treated with BA (1-4 mg L-1) and 0.35 mg L-1 GA3, shoots proliferate. The highest number of shoots were obtained in MS medium supplemented with 3mg L-1 BA and 0.35 mg L-1GA3 and the highest shoot length and maximum number of leaves were recorded in MS medium supplemented with 2.5 mg L-1BA and 0.35 mg L-1GA3. These proliferating shoots failed to yield any roots. Therefore, this could be a possible future career path. [ABSTRACT FROM AUTHOR]
