Abstract:

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. There are several drought resistant traits which have been categorized into primary traits, secondary traits, integrative traits, phenology and plant-type traits. Hence these traits are focussed for the development of drought resistance by adopting conventional and molecular strategy. Varieties like IR-36, IR-64 has been released but through conventional breeding it requires a lot of time to release a variety. Hence molecular strategy has been adopted and focus was given on adopting qtl introgression. Qtls like qDTY1.1, qDTY12.1 has pronounced effect on yield potential during drought stress. Some of the cases have been also reported that when combination of several qtls used then it showed more pronounced effect during drought stress.
