Project
Identifying the physiological and genetic traits that make cassava
one of the most drought tolerant crops
Funded by: Generation Challenge Programme (GCP), 2005-present
y g g ( ) p
Main Objectives:
• Id tif functional t it responsible for drought tolerance and yield
Identify f ti l traits ibl f d ht t l d i ld
performance under drought in cassava genotypes
• Identify molecular markers for drought tolerance traits via QTL and candidate
gene mapping towards a more efficient breeding approach for drought
performance of cassava

Identifying functional traits
SUMMARY
1) Better yielding genotypes have more open stomata, indicating they have
deeper roots and access soil water
2) Genotypes that accumulate substantial stem starch reserves may be more
able to sustain meristems and other respiring organs during a prolonged
stress
t
3) Genotypes that maintain partitioning to storage roots and have high harvest
index yield better in drought
