Explanation:

• The ‘National Bureau of Plant Introduction’ was renamed as ‘National Bureau of Plant Genetic Resources’ (NBPGR) in January 1977.
• It is a nodal organisation in India for management of Plant Genetic Resources (PGR).
• It is one of the Indian Council of Agricultural Research (ICAR) Institutes. ICAR is an autonomous organisation under the Ministry of Agriculture & Farmers’ Welfare.
• 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. 
• It has 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. Hence both statements are correct.
