Resumo
O objetivo deste estudo foi avaliar 24 genótipos da espécie Coffea arábica produzidos no IAC e trazidos da Embrapa Rondônia, selecionando materiais com potencialidade produtiva superior às cultivares locais e com resistência as principais doenças. O experimento foi estabelecido no Campo Experimental da Embrapa Acre, localizado no município de Rio Branco-AC. O delineamento experimental foi de blocos ao acaso com 24 tratamentos e 5 repetições, em parcelas com 3 covas (2 plantas/ cova), no espaçamento de 3m entre linhas e 2m entre covas. Os parâmetros avaliadas foram produtividade, altura da planta, diâmetro do caule e de copa, vigor, época de maturação e incidência de doenças. Todos os genótipos de Icatu mostraram-se tolerantes à Hemileia vastatrix. Observou-se ataque moderado de Pellicularia Koleroga em todos os genótipos testados. Os genótipos Icatu-PR-182039-1(H 4782-7-788); Catuaí SH1 EP57c-260 e Icatu IAC-4041 apresentaram as maiores produções médias de café beneficiado, 34, 23 e 22 sacas por hectare, respectivamente, mostrando-se promissores para cultivo no Estado do Acre.
The objective of this study was evaluate 24 genotypes of the species Coffea arabica produced in IAC and brought of Embrapa Rondônia, selecting materials with higher productive potential then the local cultivars and with resistance the main diseases. The experiment was established at the Experimental Station of Embrapa Acre, located in the municipal district of Rio Branco-AC. The experimental design was randomized complete block with 24 treatments and 5 repetitions in plots with 3 holes (2 plants/hole) in the spacing of 3 m among rows and 2 m among holes. The parameters evaluated were productivity, plant height, stem and treetop diameter, vigor, maturation time and incidence of diseases. All Icatu genotypes were tolerant to Hemileia vastatrix. It was observed a moderate attack of Pellicularia Koleroga in all materials studied. The genotypes Icatu-PR-182039-1(H 4782-7-788); Catuaí SH1 EP57c-260; Icatu IAC-4041 presented the largest medium productions of processed coffee beans, 34, 23 and 22 bags per hectare respectively, being the most promising for cultivation in the State of Acre.
