Abstract

Progress during Ihe past 11 years and future prospects of groundnut (Arachis hypogaea) genetic resources al ICRISAT are reviewed. The number of accessions in the ICRISAT gene bank have increased from 8500 to 13 460. However, many areas with limited cultivation but with extensive variability are yet to be covered. Most of the accessions have been characterized and evaluated for their reaction to diseases. insect pests, and other desirable characters, leading to identification of 506 useful genetic stocks. This information has been documented and is to be made avai/able in a catalog. Most of the germplasm are consen'td as pods or seeds in medium·term (4 'C, 20% RH) and long·term (-20·C) storage conditions. while rhizomatous Arachis species are consen'td as plants. lCRlSAT serves as the world's largest repository of groundnut germplasm and has distributed 60061 groundnut germplasm samples free of cost to the international scientific community involved in groundnut improvement worldwide. Despite significant progress, groundnut genetic resources activities still suffer from several limitations in assembly and characterization. The establishment of a groundnut genetic resources network is proposed to overcome many such limitations.
