The development
of a PPB Strategy took two full days (May 8 and 9). The task was introduced
to the participants as one of the main expected outputs of the Consultative
Workshop. It was suggested to formulate an independent strategy for
each crop and each country following the structure below:
|
1-
|
Introduction
(the crop, importance, area, uses) |
|
2-
|
Current
breeding program: Methodology (use scheme), achievements (variety
release, adoption) |
|
3-
|
Seed
system |
|
4-
|
Proposed
way of a) integrating PPB into the existing program, b) replacing
gradually the current program with a PPB program, c) others,
d) alternatively, reasons why PPB is not considered necessary |
This was followed by one full day (May 10) of presentations and discussions,
country by country, and within each country, crop by crop. These were,
with the exception of food legumes in Tunisia, Power Point presentations,
which are available as annexes.
In light of the discussions and the comments received, the presentations
were modified (May 11) and eventually presented in an almost (see
recommendations) final form on May 12.
The Strategy documents covered the following crops:
|
Barley
|
Jordan,
Algeria, Tunisia, Morocco, Syria |
|
Wheat
|
Jordan,
Egypt |
|
Maize
|
Egypt |
|
Faba
Bean
|
Egypt |
|
Lentil
|
Morocco |
There was a rather general consensus that PPB is an attractive approach
which deserves to be tried particularly for the more difficult environments.
The proposed strategies felt into three major categories:
|
1-
|
The PPB program seen as an additional and separate program from
the conventional breeding program for specific areas |
|
2-
|
The
PPB program integrated into the conventional breeding program |
|
3-
|
The
conventional program transformed into a fully participatory
program |
Examples of the first category are:
|
1-
|
Wheat in Egypt, for which PPB is seen as an alternative to conventional
breeding to better serve the North West Coast of the country |
|
2-
|
Faba Bean in Egypt where in the new land there are opportunities
to expand the cultivation of the crop which have not been met
by conventional breeding |
|
3-
|
Maize in Egypt where PPB is seen as an alternative to conventional
breeding for the newly reclaimed land |
|
4-
|
Barley in Syria, where the National Program is still reluctant
to accept participatory plant breeding; they consider the conventional
breeding program fully successful and the low adoption of the
barley varieties released so far is attributed to the high price
of certified seed. |
Examples of integration of a participatory component in a conventional
breeding program are:
|
1-
|
Barley in Tunisia and Algeria, and barley and lentil in Morocco.
In these countries barley is a typical crop of marginal environments,
and there has been so far very limited adoption of the varieties
developed with conventional plant breeding. |
Eventually Jordan is the only example of a situation in which as a
follow up of the workshop the national breeding program will start
a process of transformation of the centralized non participatory program
into a participatory program. The first step of the process will be
implemented in the 2005/2006 cropping season for barley and in the
2006/2007 cropping season for wheat. The process will be completed
in four cropping seasons.
Methodologies
The methodologies proposed by the participants to implement the participatory
programs are largely based on the pedigree method with sets of trials
planted in farmers' fields and the selection done by the farmers.
In the case of the maize PPB program proposed for Egypt the methodology
is base on the concept of the mother and baby trials.
In the case of the programs proposed in Algeria, the methodology includes
the incorporation of the haploid breeding.
Germplasm
Most of
the proposed strategies include the use of local germplasm. The barley
breeding program in Morocco is actually divided in two components,
and the component which addresses the marginal areas is almost entirely
based on landraces. Similarly the strategy proposed for barley in
Tunisia and Algeria and for lentil in Morocco includes the collection,
the evaluation as well as crosses with local landraces. In the case
of the barley and the wheat breeding in Jordan, the strategy includes
the flow of local germplasm (landraces and wild relatives, from the
local gene bank into the breeding program after one cycle of seed
multiplication on station.
Limiting factors
The strategies identified the following factors limiting the applicability
of PPB
|
1-
|
Partners' commitment: the application of PPB requires a strong
collaboration between the breeder, the extension services and
the farmers. Therefore, the government needs to establish some
formal status, which would enhance this collaboration; |
|
2-
|
Farmers educational level: farmers' low level of education may
make it difficult to appropriately implement PPB; |
|
3-
|
Variability in farmers' typology; |
|
4-
|
Variety homogeneity aspect: some flexibility in the regulation
has to be made to make the PPB varieties accepted for release,
at least for specific environment. For some crops, such as durum
wheat, seed homogeneity may constitute a quality constraint
for its transformation. Therefore, it is important to think
of developing some artisan units for transformation as territory
product; |
| 5- |
Variety sustainability: since the varieties released through
PPB may be maintained by farmers themselves, some technical
supervision is needed to ensure their sustainability, particularly,
during difficult years; |
| 6- |
One of the most important limited factors is the financial support
because in developing countries there is no additional fund
to carry out participation plant breeding; |
| 7- |
Breeders' background with limited information about PPB and
its importance to release new varieties adapted to a wide or
specific sites; |
| 8- |
Qualification of the Extension staff |
| 9- |
With specific reference to Syria, it was felt that PPB is not
sufficiently clear for a number of scientists. |
