14. Existing genetic material
including the available cultivars
could be useful
to breed new material
with resistance to new climate change
This require detailed information
about the characterization and evaluation
of existing genetic material (including cultivars)
which are adapted to a wide range of agro-environments

29. Importance !
New hybrid material could be resistant
to new evolved pests and diseases,
this material needs further evaluation
30. Challenges:
- Lack of characterization and evaluation data
for resistance to abiotic stress (drought, heat tolerance).
-Require developing phenotype tests for abiotic stress resistance
and need knowledge and expertise.
-Lack of knowledge of the interspecific relationships and
genome interactions for many taxa.
- Long term return for pre-breeding of exotic germplasm.
- Requires high professional staff.
- Requires large investments.
31. Perspectives:
- Exchange of ideas, experience, material.
- Importance of national and international communication and collaboration
- Importance of active collaboration between the research communities.
