Despite Ethiopia is endowed with diverse genetic base for the Arabica coffee and is the center of origin for it, there is still a limited availability of yield competitive improved variety; hence, the national average productivity is far below the world’s average. For contributing in filling the existing gaps, identification of improved hybrid Arabica coffee varieties that are stable, high yielding and disease resistant are necessary for south coffee growing areas of Ethiopia. Therefore, this experiment was conducted at Awada, Komato & Wonago to depict the growth and yield characteristics of five Arabica coffee promising hybrid genotypes (744xAngafa, 7440x2077, 75227xAngafa, 75227x2077 and 75227x1681) and 2 standard check (Ababuna & Angafa). The experiment was conducted by using randomized complete block design (RCBD) with three replication during the years 2006 to 2014. Data were collected for eight growth characteristics and yield for five consecutive years (2010 to 2014) per hectare basis. The results revealed that the existence of statistically significant variations for interaction effect of three traits and for the main effect four traits. The highest plant height 323.3 cm & 307.77 cm were recorded at Awada & Wonago respectively; highest length of longest primary 114.43 cm & 108.86 cm was observed at Komato & Wonago respectively. Statistically highest canopy diameter (214.31 cm), stem girth (6.78 cm), number of main stem node (57.68) and number of nodes on longest primary branch (29.57) were observed at Awada, Awada, Wonago and Komato growing condition respectively. The study result revealed that total yield per hectare was higher for promising hybrid 744 x Angafa (2067.8 Kg/ha) followed by 75227x1681 (1955.1 Kg/ha) grown at Awada and for 75227xAngafa (1169.2 Kg/ha) at Wonago. As the promising hybrid genotypes out performed than the existing improved varieties at Awada and Wonago, there will be a better chance of getting improved Arabica coffee hybrid varieties within south Ethiopian growing environment. Therefore, the experiment should be repeated in different representative trial site to recommend suitable and stable hybrid variety for south coffee growers.
