The establishment of the Bureau coincided with the advent of the Green Revolution and was in response to the realization of perceived effects of the Green Revolution on agrobiodiversity. Further, it was in accordance with the international developments in the form of establishment of the International Board for Plant Genetic Resources (IBPGR), Rome, in 1974 (now renamed as International Plant Genetic Resources Institute). The NBPGR played a pivotal role in the improvement of various crop plants and diversification and development of agriculture in India through germplasm introduction from various institutes/organizations located in foreign countries and germplasm collection from within the country and abroad and conservation thereof. The National Bureau of Plant Genetic Resources (NBPGR) has its headquarters at New Delhi, located at latitude of 28⁰ 35’ N, longitude of 70⁰18’ E and an altitude of 226 m above mean sea level.  The Bureau draws guidelines from the Crop Science Division of ICAR, Institute Management Committee, Research Advisory Committee, Institute Research Council and Germplasm Advisory Committees. The Bureau has five Divisions, three units and an experimental farm at its Headquarters in New Delhi and 10 Regional Stations located in different phyto-geographical zones of the country.  Besides, an All India Coordinated Research Network Project on Under-utilized crops are located in the Bureau.
