3. Results and Discussion

4. Summary and Conclusion

•Ethiopia is Africa’s top producer

20 mln people engaged in production,

processing, export and service provision

• Annual production = 419,980 tons

Total area coverage= 561,761ha

Average productivity = 757kg/ha

• Ethiopia possesses about 99.8

% of the total Arabica’s genetic

diversity

• The country is ecologically very

diverse and coffees grown

under these environments are

different for several other traits

• Development of breeding

strategy that fits to these

conditions is imperative to

exploit all the available

advantage

• The application of local land race development

strategy achieved the development of 11 coffee

varieties for speciality coffee growing areas of

Sidama Yirgachefe, Harar and Wellega

• In this presentation, assessment of Limu

CBD resistant mother trees for Yield and

major coffee diseases are discussed.
