Propagation

a) Seed:

• Jackfruit is commonly propagated by seeds.
• Seed should be sown immediately after extraction since they lose their viability during storage.
• Soaking seed in NAA (25 mg/L of water) for 24 hrs improve their germination and seedling growth.

b) Air layering:

• It is one of the best methods to obtain true to type plant.
• Air layering of one-year-old shoot of bearing plant gives higher success when treated with IBA (500 ppm).

c) Epicotyls grafting:

• Jackfruit seeds should be sown in poly bags (l0cm x 20cm) in the 1st week of July.
• The seedlings when reached 12-14 cm heights should be used as rootstock for grafting.
• Scions from the terminal shoot of selected good variety of one season old, having well developed buds should be used.
• At the base of the individual scion a wedge of 4.0 cm should be prepared and inserted in the split epicotyls region of the stock and tied firmly by polythene strips.

d) Patch Budding:

• Teaotia et al. ( 1963) reported 100 percent success by patch budding.
• Patch, chip and T methods of budding were tried during February to September by Singh et al. (1982).
• The maximum success ( 90 percent ) was obtained following patch method in June and T budding was found successful.
