Recalcitrant seeds loose viability on drying or their exposure to chilling temperature and are difficult to store for longer periods. An assured supply of seeds for grafting as a rootstock during the lean period can be achieved only from the seed stock held in storage. Jackfruit (Artocarpus heterophyllus Lam.) seeds are recalcitrant in nature and lose viability during storage. Hence, an investigation on seed viability of jackfruit and methods to prolong it under artificial storage conditions was conducted. The experiment was conducted with eight seed storage methods and six storage periods with two replications in factorial randomized block design. A hundred seeds per treatment per replication was the unit. It was revealed that the loss in moisture content of the seed was negatively associated with the germination percentage, days to first germination, days required for 50 per-cent germination, germination period, germination index, germination value, seed vigor, seedling vigor index and the height of the seedling from such germinated seed was seriously hampered.
