Green revolution has brought transition in rice cultivation and architecture of plant. Further, the present way of rice cultivation system has been considered to be labor intensive, requires more of fresh water that yields marginal profit.Change in climate and stiff competition for quality water has warrant rice farmers to change their system of cultivation from transplanted to dry direct seeding. The changing climate scenario and reduced water availability has shown marginal increase in area of direct seeded rice. The dry direct seeded rice has changed the way of rice cultivation that requires less water, labor and promotes rice plant to be more efficient for nutrient than the existing one. Therefore, rice plant breeders are involved in developing suitable genotype adaptable for mechanized system of farming from sowing to harvest with increased efficiency towards water and

nutrient.
