What do we know?
- Can be Propagated by root cutting, air layering, stem cutting, grafting, T.C Methods, seeds
Where are we now?
- Studies already started
- Selected clones being propagated
- Root cuttings main method, higher success rate
- In-vitro propagation (under experiment)
- Air-layering(under experiment)
- Grafting
Where should we be?
- Should have already mastered vegetative propagation methods
- Should have already large number of breadfruit plants for sale
- Planting material at affordable price (current price at Barkley Rs 185/unit)
What is missing to get there?
- Research facilities and funds
- Skilled labour
- Need more starting materials

What questions are we asking ourselves?
Question: Tapping funds (from where)?
Answer:
Question: Training for propagation required?
Answer:
Question: Pros and cons of propagation method
Answer:
- Generally propagated vegetatively from root shoots or root cuttings ,air layering or from seeds
- Can also be grafted
- In vitro plantlets also being developed
- Seeds are rarely grown because do not develop true to type
- Root shoots or cuttings are preferred methods
Question: Is any method of propagation highly recommended?
Answer:
Question: What are the success rates of the different propagation methods?
Answer:
- Stem cuttings-may get 95% success
- Air layering -50% do not root.Planted at 1 year stage in the field.May bear fruits 1-2 years after planting.
- Stem cuttings-95% success .Planting at 4 months stage in the field.
- Grafts-carried out on seeded rootstock or wild jack fruit trees.can bear fruits in 2 years
- In vitro method still under experimentation
Question: Do we have facilities for mass propagation (large scale)?
Answer:
- The tissue culture lab of FARC has already fine tuned protocol for large scale in-vitro propagation of local germplasm, however, trial for conditioning & hardening still ongoing.
Question: What are the problems encountered for different propagation methods
Answer:
- Availability of root suckers is a major problem for vegetative propagation for Barkly Experimental Station, Agricultural Services, Ministry of Agro-Industry & Food Security
Question: Is it easy to propagate by in-vivo methods
Answer:
Question: What if someone use root cuttings from grafted plants
Answer:
Question: Is there any subsidized price for large scale?
Answer:
Question: What are the current prices?
Answer:
- Price of potted plant -Rs 185/unit at Barkly Experimental Station, Agriculturla Services, Ministry of Agro-Industry & Food Security
- Price of potted, hardened T.C plant at FARC-Rs 125/unit
- Price of grafted plant at Labourdonais-Rs 500/unit (to be confirmed)
Question: Cost effective method of propagation
Answer:
Question: Where to get readily available planting materials?
Answer:
Question: Do we have enough planting materials and root stock?
Answer:
Question: Which rooting system/ propagation method is suitable against cyclone?
Answer:
Question: Who is and how to coordinate gathering of information on amount of planting materials available, rate of production?
Answer:
Question: which institutions have capacity to do this? Private sector?
Answer:
Question: Can people /farmers/ students be trained on grafting techniques?
Answer:
Question: Who can/will train producers on propagating methods?
