The choice of promising genotypes from diverse genetic bases and subsequent utilization of hybrids is one of the breeding strategies to improve productivity. Hence, the present experiment was conducted among elite coffee materials from Western Ethiopia. The data were recorded for five stem-, four branch- and three leaf- characteristics. The analysis of variance revealed highly significant (P<0.001 and P<0.01) differences among the 15 genotypes (5 parents and 10 F1s) for all traits except for total number of nodes, leaf area and number of nodes per primary branch. The combining ability analysis of variance showed significant general (GCA) and specific (SCA) combining ability mean squares for nine out of 12 characters measured, indicating the importance of both additive and non-additive gene actions. Parent P1 consistently exhibited positive GCA effects for nine characters, parent P2 for five characters and parent P4 for seven characters suggesting that these parents are good general combiners. Hybrids P2 x P5, P2 x P4, P2 x P3, P3 x P4 and P1 x P5 were noted with High and positive SCA effects for each character. Therefore, it could be useful to include such potential hybrids in a breeding program and further evaluate their performance for yield and growth characteristics at full full-bearing stage.
