The Directorate of Oilseeds Research (DOR) formerly operating as  All India Coordinated Research Project on Oilseeds(AICORPO) came into existence on August 1, 1977 with the Headquarters at Rajendranagar, Hyderabad. It operated with a Project Director as its administrative head and seven Project Coordinators for groundnut, rapeseed-mustard, sesame, linseed , castor, safflower, sunflower and niger.  Subsequently, groundnut and rapeseed-mustard were delinked from the Directorate with the establishment of National Research Centre for each of these crops during 1979 and 1993 respectively. In April 2000, the AICRP on Sesame & Niger and Linseed have been separated from the administrative control of DOR. The Directorate has in its fold the mandate of working on  castor, safflower and sunflower.
