CIMMYT’s
research
has
informed
the
agenda
of
maize
breeding
programs
in
sub-­‐Saharan
Africa,
to
ensure
that
new
varieties
developed
will
be
tolerant
to
heat
stress
as
well
as
drought.
CIMMYT’s
climate
projections
for
maize-­‐producing
areas
in
sub-­‐Saharan
Africa
highlighted
the
increasing
prevalence
of
heat
stress
and
identified
hotspots
of
vulnerability.
Researchers
analysed
commercially
available
maize
varieties
and
new
drought
tolerant
varieties
developed
under
the
Drought
Tolerant
Maize
for
Africa
(DTMA)
project,
by
phenotyping
and
modelling
crops
under
expected
future
climates.
The
results
highlighted
the
susceptibility
of
these
varieties
to
increased
heat
stress.
The
research
also
identified
potential
yield
gains
that
could
be
made
through
adapting
the
existing
breeding
pipeline
to
address
the
potential
effects
of
future
climates,
particularly
heat
stress.
