Getting more information on genetic variability is a prerequisite for further improvement of coffee (Coffea arabica L.). Although Ethiopia is known as a primary diversity for Coffea arabica the knowledge on nature and extent of variation of the coffee accessions has one of the major problems in coffee improvement program. Hence, to assess the nature and extent of variability on agro-morphological traits, test trial was conducted at Awada, Southern Ethiopia. The trial was consisted one hundred twenty Sidama land race Arabica coffee and four standard checks and arranged in augmented design with four replications of the checks. Analysis of variance showed significant difference among the tested genotypes for most of the quantitative traits considered in the study, indicating the existence of sufficient genotypic variation among the coffee accessions. Phenotypic coefficients of variation ranged from 4.52 (fruit length) to 60.89 (coffee berry disease) while, genotypic coefficients of variance ranged from 3.92 (bean width) to 56.52 (coffee berry disease). Likewise, high broad sense heritability coupled with high genetic advance as percent of the mean were observed for coffee berry disease, average green bean yield, stem diameter, average inter node length of stem, plant height, number of primary branches and average length of primary branches confirming that genotypic variance has contributed substantially to the total phenotypic variance.
