In India cassava breeding is done mainly at the Tuber Crops Research Institute (CTCRI) in Trivandrum, as well as in the State Agricultural Universities through the All India Co-ordinating Centres. CTCRI maintains 786 exotic and 848 indigenous accessions of cassava and 8 wild species in its germplasm bank. Coordinating Centres maintain about 280 indigenous accessions. Seedling progenies of 158 and 19 CIAT cassava accessions were screened at the Regional Centre of CTCRI in Bhubaneswar during 1985 and 1990, respectively. High root yields of more than 4 kg/plant were recorded in seedling progenies of CM3426, CM4046 and CM4229. Selection of promising germplasm and hybridization among selected accessions have been the principal strategies in cassava breeding.
