Development of drought resistance in rice

With the change in the global scenario drought is becoming one of the major problem among other stress and its effect is more severe in rice whose life cycle completely depends on water. Whether it occurs during any stage (early, intermittent and late) it affects crop and its effect is more severe when this stress coincides with reproductive stage of the crop growth. However, rice respond to it by sending signals to shoot which generates signals in terms of physical, chemical and biological form. Hence, screening of plants at this stage is most effective for development of drought resistance.
