Coffea arabica is angiosperm plant and propagates by seed like other coffea species. Limited quality coffee seed production and supplying system is currently challenging issue. Thus, the present review conducted with the intension of factors affecting quality coffee seed production and its supplying system in Ethiopia. The two principal factors that affect quality coffee seed production are pre-harvest and post-harvest factors. Pre-harvest factor include field management practice, insect pest and disease and stage of fruit maturity; while seed drying method, seed storage time, seed initial moisture content and types of container for seed storage are post harvest factors. Deep reddening and reddening stage fruit used for seed showed more than 88% germination; but at yellow and green stage germination was 70% and less. Seed drying under corrugated iron and glass tukul enhanced germination up to 80% and more; but under open sun it ceased to 70%. Seedling emergence percentage rapidly decreased after 3-5 months of storage time; hence, seed sowing to nursery as soon as harvesting without further storage increase seedling emergence and make earlier the attain first true leaf and mean day of germination. Seed with initial moisture content of 55.2% stored in glass jar recorded 97.5%, 89.1%, and 84.5% in seed viability; seedling emergence percentage and seedling attain first true leaf respectively after 5 months storage. Jimma Agricultural Research Center (JARC) has released 42 improved coffee varieties up date, and distributed 341.821 ton and 347,308 coffee seed and seedling respectively. However, seed demand and supply is not compatible as a result of seed supply system problems in Ethiopia. Formal coffee seed supply system mandate given to JARC, and well established informal coffee seed supply system is lacking in Ethiopia. Thus, for further technology disseminate and to response seed demand, formal and informal coffee seed supply need to be diversified with strong agricultural extension work in Ethiopia.
