Seventy three exotic collections of cassava (Manihot
esculenta Crantz) germplasm were evaluated for 10 yield
and quality characters. Eight out of ten characters showed
high variability. Following nonhierarchical Euclidean
cluster analysis all the 73 genotypes were grouped into
six clusters with variable number of genotypes.
Accessions of heterogenous origin or place of release
often grouped together in the same cluster, suggesting
some degree of ancestral relationship between the
genotypes. On the basis of the data on genetic divergence
and the mean performance of yield and other traits seven
diverse and superior genotypes were selected for use in
breeding.
