Resumo
Analisaram-se as características da bebida de alguns cafeeiros híbridos (Coffea arábica x C. canephora) que deram origem ao icatu, e de plantas pertencentes a nove populações deste cultivar. A qualidade da bebida dos cafeeiros originais mostrou-se semelhante à do arábica, variando de "mole" a "apenas mole". Nas populações de icatu foram efetuadas 1953 determinações. Verificou-se que a bebida não difere daquela produzida pelo cultivar acaiá (C. arábica), tomada como padrão. Em escala de cinco pontos, 63 (3,2%) determinações deram bebida "dura" e 1324 (67,8%), "mole", enquanto o acaiá apresentou bebida "mole". Na escala de 10 pontos o número 3 foi dado a nove determinações (0,5%) e o máximo de nove pontos a 677 (34,6%), sendo de 7,7 a média de pontos conferida ao acaiá. Verificou-se que as populações H 3849-7, H 3851-4 e H 4782-7 apresentaram médias de pontos mais elevadas e que as populações H 3849-14-2 e H 3849-14-3 deram as menores médias, nas duas escalas de valores. As populações examinadas não diferem do acaiá quanto à qualidade da bebida, podendo ser utilizadas comercialmente.
Cup quality determination was undertaken for a group of coffee seed samples of interespecific (Coffea arábica x C. canephora) trees, which gave rise to the Icatu cultivar and also for nine Icatu coffee populations. The original hybrid plants showed cup quality similar to the Arábica control, with exception of one single plant which gave lower quality. For these populations a total of 1953 cup quality determinations were made by three independent coffee drinker experts. Two scale ranking from 0-5 and 1-10 were used for the evaluation. It was verified that the average grades of each one of the nine Icatu populations did not differ "from the ^Arábica. In the scale (0-5) the grade "Hard' occurred in 63 determinations (3.2^) an the "Soft" cup quality in 1324 determinations (67.8%). In the 10 points scale 3 points were attributed to nine determinations (0.5%) and 9 points to 677 (34.6%) determinations. The H 3849-7, H 3851-4. H 4782-7 Icatu populations presented the higher graded cup quality and H 3849-14-2 and H 3849-14-3, the lowest ones. The cup quality variability and occurrence of individual selected plants with high cup quality similar to the Arábica used as control pointed out the possibility of using the Icatu cultivar for commercial planting.
