Clonal propagation of Artocarpus heterophyllus (Lam.) through in vitro culture has been established using explants from both the mature elite trees (Roy et al. 1990; Roy 1991; Amin 1992a) and seedlings (Rahman 1988; Rahman and Blake 1988). Nevertheless, multiplication rate, as achieved so far, is not satisfactory for large scale plantation of jackfruit woodlot. Moreover, some of the previous work have shown strong effect of aging or rejuvenation. On the contrary, with very juvenile material, such as embryo, it was possible to avoid these problems in other plants (Heile-Sudholt et al. 1986). As such the present investigation was undertaken for mass propagation of jackfruit plantlets through embryo culture in vitro.
