An evaluation of resistances of thirty Arabica coffee genotypes for coffee berry disease (CBD) and coffee leaf rust (CLR) infections were carried out across different locations in south-western Ethiopia. The genotypes were first screened against the diseases at Gera which is high land. Eighteen out of thirty genotypes were found to be highly resistant to CBD. However, the earlier screening against CLR at Gera did not favor selection of genotypes which exhibited high resistance levels to it except 75187B, 8136, 8143 and 7803B showing high land is not an optimum environment to discriminate among genotypes for rust resistances. The resistances of these genotypes for rust at multi-locations with different races of rust indicate that they are resistant at least to the two prevalently localized races of II and III in south-western Ethiopia. The identification of Arabica coffee types resistant to coffee leaf rust at multi- locations shows the possibility of improving genotypes for CLR resistances. Genotype 75187B and 8143 apart from exhibiting multiple resistances for coffee berry disease and coffee leaf rust; they also exhibited high performance for yield at the stated locations. This indicates that it is possible to improve the indigenous Arabica coffee types in Ethiopia for multiple traits simultaneously.
