Rainfed rice - IRRI books - International Rice Research Institute

During 1965-72, 6630 accessions were collected by the Indian
Agricultural Research Institute (IARI), New Delhi, in cooperation with
the International Rice Research Institute (IRRI), Philippines. The
collection was known as the Assam Rice Collection (ARC).

About 19,116 accessions collected under the leadership of Dr R. H.
Richharia from Madhya Pradesh formed the Raipur Collection.
Joint exploration of CRRI with state agricultural universities resulted in
the collection of about 7000 accessions during 1978-80 and 447
accessions during 1985.
National genebank
Rice Biodiversity and Genetic Wealth
The National Bureau of Plant Genetic Resources (NBPGR) has one of the world's
largest genebanks. More than 45,000 accessions of rice germplasm are conserved
here as base collections in cold storage modules at -20° C.
Restoration of germplasm
Several accessions of traditional cultivars in Assam and neighbouring regions in
northeastern India were jointly collected by IRRI and national scientists in India. Much of
the original Assam Rice Collection had deteriorated or had been lost. A duplicate set of
5311 accessions from the collection was sent by IRRI to NBPGR. The collection
maintained by CRRl was also duplicated by IRRI and sent to NBPGR.
