Evaluation of arabica and robusta coffee genotypes in western Amazonia :

The behaviour of 15 genotypes of arabica coffee (Coffea arabica) and 1 of robusta coffee (C. canephora cv. Conilon ES) was evaluated under the edaphoclimatic conditions of Rio Branco in the state of Acre from 1989 to 1996, with plants in a randomized block design, with 5 repetitions. Yield of "cherry" fruits and coffee beans, vigour, total height, stem diameter and plant disease status were evaluated. Icatu PR182039-1 and Conilon ES produced the highest average yield of beans (4.345 and 4.147 kg/ha,respectively), followed by Catuai SH1 EP57C260, Mundo Novo and Catuai SH1 EP57C166 with yields above 2.8 kg/ha. Mundo Novo and Catuai Amarelo presented the highest incidence of Hemileia vastatrix, and Catuai EP57C260 and Catuai EP57C166 were most susceptible to Pellicularia koleroga [Koleroga noxia]. Icatu PR182039-1, Conilon ES and Catuai SH1 EP57C260 were superior to the other genotypes with respect to plant vigour, yield capacity, and appearance of the cherries and beans, and show promise for cultivation in western Amazonia.
