Germplasm

Page history last edited by Nawsheen Hosenally 8 years, 11 months ago

Please find below the Literature Review on Germplasm and also the outputs from the Workshop Group Activities. What we need to do now is to try to get answers to the questions that we have and any additional information that we have on this theme may also be added under the respective heading. 

 

To answer the questions below, simply click Edit on the top left corner, write your answer or any additional information and Save (at the bottom of the page).

Note: Anyone who is replying to a question is requested to put your name (in brackets) at the end of your answer or complementary information.

If in doubt, just add as a comment.

 

 

What do we know? 

  •  Twenty varieties identified as core varieties (literature)
  •  Can be conserved by tissue culture(literature)
  •  Seem to have two varieties or phenotype locally (round & oblong)(observation)
  •  Breadnut can be used as root-stock for grafting (local validated practice)
  •  Breadnut has an edible seed (high protein)(literature)

 

Where are we now? 

  •  Propagating only two seedless varieties locally
  •  In vivo production of plants using root only (Literature Revue agricole)

 

Where should we be? 

  •  Characterisation of our varieties (morphological & molecular)
  •  Any development project for which we need new germplasm
  •  Introduction of new varieties if there is a need
  •  In-vitro propagation

 

What is missing to get there?

  •  Breadfruit to shift from an under-utilized crop to a commercial crop
  •  Collaboration with international and local institution dealing with Breadfruit

 

Stakeholders involved in issues related to germplasm

Who?

Why?

How?

1. UoM

  • Studies on general erosion or drift in local varieties
  • Research existent and facilities available
  • Students Projects

2. AREU

  • Varieties existing in Mauritius
  • Introduction of new varieties
  • On-going research on breadfruit
  • Research on usefulness of breadnut regarding nutritional properties and on a rootstock
  • Survey by Extension services
  • Evaluation Trials
  • Collaborative programs (UoM?) 

3. MAIFS (NPPO & Entomology)

  • Facilitate introduction of new germplasm
  • PRA & Disease/Pest surveillance

4. MAIFS (Horticulture division)

  • Already involved in conservation
  • In-vitro/In-vivo collections

5. FARC

  • Already involved in conservation of germplasm
  • In-vitro-collections

6. Research organizations in different countries

  • Already involved in Research and development
  • Collaborative programs
