International Network for Cassava Genetic Resources. Rome, Italy, 1999. Report of the first meeting. cali, Colombia, CIAT, IITA-IBPGR, 1992  aThe needs of cassava breeders in terms of genetic diversity are focused in relation to the objectives pursued by national and regional programmes. Genetic diversity has been identified in cassava for most of the important ttraits. Actual and future needs should be based upon famer, processor and consumer demands. Those demands are mainly determinedby biotic and abiotic factors affecting the crop and by the way cassava is utilized. Presently, the major demands for genetic diversity in cassava are dry matter productivity, resistance to pests and diseases, adaptation to water and cold stress, and root quality for fresh or processed consumption.  apests  aDoença  aMelhoramento  acassava breeders  aDiseases  aDiversidade genetica  aGenetic biodiversity  aPragas  tCIAT, Cali, Colombia: IPGRI, 1994
