• 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.
