In Ethiopia, multiplication and distribution of the released F1 hybrid coffee varieties for producers were constrained by the problems associated with methods of propagation. An experiment was conducted on propagation by cuttings using F1 hybrid coffee Ababuna with the objective to determine and select suitable potting media mixture to carry out rooting directly in polythene bags under low cost propagating structure. Five rooting media in a randomized complete block design with four replications and 30 cuttings per treatment was used. Data on percent rooting and other root and shoot parameters were collected and analyzed using analysis of variance (ANOVA). The result indicated that most of the parameters measured, except for shoot development, were significantly influenced by potting media types. Accordingly, rooting media composed of 3Ts + 1S and Ts+10cm Fw ss on which cuttings produced significantly higher percent of rooting, root number and length were recommended and further investigation focused on the remaining hybrids and combination of alternative factors was also suggested to come up with conclusive recommendation to obtain sufficient number of rooted cuttings.
