In order to fulfill these mandate effectively, IIRR is organized into four sections and ten units along with centralized service wings and administration. AICRIP activities are integrated into the mandate with senior most scientists of each discipline acting as the PIs of the programme. Research and institutional activities are planned and guided by Research Advisory Committee and Institute Management Committee while the progress is critically evaluated once in five years by the Quinquennial Review Committee.
The Institute has well equipped laboratories with state of the art equipments, centrally air cooled greenhouses, bio-safe transgenic greenhouses, growth chambers, well laid out experimental farm and digital enabled library facilities. IIRR also coordinates rice research at 45 funded and over 100 voluntary centers under AICRIP.
