Agronomic evaluation of coffee germplasm collection in the state of Paraná, Brazil
During the period from 1977 to 1982 a trial was carried out in Jacarezinho, PR, Brazil, with 18 introductions of coffee (Coffea arabica L.) to assess the yield potential, plant architectural features, fruit maturity, bean characteristics and reaction to leaf rust and leaf miner. Results were compared with those of cultivar Catuaí-Amarelo which is extensively planted in Brazil and lcatu. Differences in yield and other traits among plants were significant. Nine introductions showed similar yield when compared with Catuaí-Amarelo (4,629 kg/ha). Four have shown dwarf habit, and fourteen presented early fruit maturing characteristic. All introductions were susceptible to coffee rust, produced high percentage of flat beans and low percentage to shell-beans. The introduction T-974 was lesser attacked by leaf miner.

Durante o período de 1977 a 1982 conduziu-se um experimento em Jacarezinho, Paraná, com 18 introduções de café (Coffea arabica L.), com o objetivo de avaliar o rendimento de produção, arquitetura das plantas, maturação, características da semente, e o comportamento das plantas quanto à reação à ferrugem-alaranjada e ao bicho-mineiro. Os resultados foram comparados com o da cultivar Catuaí-Amarelo que é extensivamente cultivada no Brasil e Icatu. Houve diferenças significativas em produção e em outras variáveis, entre as plantas. Após quatro colheitas consecutivas, nove introduções produziram café beneficiado similar ao da cultivar Catuaí-Amarelo (4.629 kg/ha). Quatro caracterizam-se pelo porte baixo, e quatorze, pela maturação precoce dos frutos. Todas as introduções foram suscetíveis à ferrugem e apresentaram altas percentagens de semente tipo chato e baixa percentagem de semente tipo concha. A introdução T-974 foi menos atacada pelo bicho-mineiro.
