Description Conservation of crop germplasm diversity involves the establishment of in situ and ex situ
genebanks. The major activities for ex situ genebanks include assembling, conserving, characterizing
and providing easy access to germplasm for scientists. More than six million accessions
are currently assembled in over 1300 genebanks worldwide. ICRISAT is one of the 15 CGIAR
centres, with headquarters at Patancheru, India, and conserves genetic resources of sorghum,
pearl millet, chickpea, pigeonpea, groundnut, and six small millets. The ICRISAT genebank
holds 114,870 accessions from 130 countries, including both archival materials from various
organizations throughout the world, and from fresh collections resulting from 213 missions
in 62 countries. The ICRISAT genebank supplies annually over 40,000 germplasm samples
to scientists worldwide. Sixty-six varieties selected from the basic germplasm have been
released for cultivation in 44 countries, and ICRISAT has restored/repatriated crop germplasm
to eight countries. The research focus is on germplasm diversity assessment, developing core
and mini-core collections, and using a molecular characterization approach to both enhance
the utilization of germplasm in research and improve the efficiency of germplasm management.
Following these approaches, we have been able to identify a significant number of
accessions with traits potentially relevant for crop improvement.
