Abstract: Coffee (Coffea arabica L.) belongs to the genus Coffea, in the family of Rubiaceae. About 139 coffee species are known in this genus, whereas Coffea arabica L. and Coffea canephora are the two most widely cultivated species worldwide. Coffee arabica has its primary center of diversity in the highlands of southwest Ethiopia then disseminated to different world’s continents by different agents. The objective of this review is to indicate the access of genetic variation among Ethiopian Arabica coffee germplasm for future breeding use. Morphological markers in coffee are vital to distinguish variation based on external observation differences, such as shoot character like: - color of the shoot tip, fruit and bean character, branch and stem character. So far, genetic variability study in coffee was conducted by many scholars coffee germplasm collected from different agro-ecologies. The availability of wide genetic variability among the indigenous coffee and the diverse agro-ecologies in the country provided immense possibilities to improve coffee for desirable agronomic and breeding interest traits. Moreover, outstanding achievements have been recorded in collecting 7130 germplasm accessions, generating basic information on the genetics aspects, and developing 44 improved varieties of which nine are F1 hybrids.
