The experiment was conducted at Jimma Agricultural Research
Centre. The objective of the experiment was to evaluate the
genetic diversity of cassava using agronomic traits so as to
characterize and cluster with in collected cassava
genotypes. Thirty five cassava genotypes were sampled from
the collection. Relatively high broad sense heritability was
observed for plant height (42.08) and root diameter (31.88)
indicating the existence of possibility for selection of
genotypes for high fresh tuber weight. The clustering of
genotypes based on 11 quantitative traits revealed the
existence of five distinct groups. The maximum inter cluster
distance was observed between genotypes under cluster II and
V and I and V, hence, the genotypes grouped in these
clusters could be used for crossing if high fresh tuber
yield genotypes are planned in breeding program.
