Several agronomic characteristics were studied in progenies from open pollinations and hybridizations of coffee trees C1195-5-6-1 and C1195-5-6-2. Both, resistant to the leaf miner (Perileucoptera coffeella), bloom profusely and are early ripening, characteristics of Coffea racemosa from which they originated via backcross to C. arabica. Hybrids of these two individuals with Icatu, Catimor, Híbrido de Timor and Catuaí cultivars were evaluated. The first three cultvars, C. canephora x C. arabica backcross derivatives, are resistant to the leaf rust (Hemileia vastatrix) and the last a leading C. arabica cultivar has short stature and high yield capacity. The study of the progenies, undertaken in four experiments revealed that all these attributes, of such a diverse germoplasm, are genetically inheritable and are present in the progenies in different associations. The yield data and the fact that there are no antagonistic correlations among those attributes suggest that is possible to develop high yielding leaf miner resistant cultivars with other additional favorable traits, mainly resistance to leaf rust.
