Similarity level of secondary data on proximate composition of fufu flour measured from 44 cassava mosaic diseases (CMD) resistant varieties was obtained in order to group the 44 cassava varieties. The distant coefficient generated between the 44 CMD resistant varieties ranged from 0.000 to 51.510. The distance measures with low coefficient are grouped together. The agglomerative hierarchical schedule showed that the varieties could be placed in five distinct groups. The dendogram of the study which showed the relative size of the proximity coefficient at which cases were combined was obtained.


Key words: Similarity level, agglomerative, hierarchical schedule, proximity coefficients, proximate composition, cassava mosaic diseases (CMD)-resistant varieties.
