4 Conclusions
Drought stress is a serious threat to rice production
in rainfed upland; it affects every stage of growth
and development. Timing, duration, severity and
speed of development undoubtedly have pivotal
roles in determining how a plant responds to water
deficit and this makes breeding for drought
tolerance a herculean task. A model for upland rice
breeding programme capable of identifying superior
genotypes for drought prone upland ecosystem can
be developed by screening genotypes under drought
stress and select for least percentage reduction in
physiological and productivity traits when breeding
materials are subjected to stringent water stress.
