dc.description.abstract The aim of this study was to evaluate the coffee germplasm of the Paraná Agronomic Institute (IAPAR) for resistance to the coffee-berry-borer. Preliminary field evaluation was performed in August 2004 and the fruits of less damaged genotypes in the field were evaluated under controlled condition with obligated and free choice experiments established in a randomized complete design with three replications. The genotypes were evaluated fifteen days after infestation with one borer per fruit in Petri dishes. The data were analyzed by the Scott-Knott means test at 1 % and by the χ 2 test. Statistical analysis indicated that Coffea kapakata, Psilanthus bengalensis, C. eugenioides and genotypes with C. eugenioides genes were resistant. These genotypes presented low frequency of bored grains. C. eugenioides and C. kapakata could present resistance at epicarp level but not in the grain. P. bengalensis could present resistance also in the grains. pt_BR
dc.description.abstract O objetivo deste trabalho foi identificar fontes de resistência genética a H. hampei em diferentes espécies de café do banco de germoplasma do Instituto Agronômico do Paraná (IAPAR), Londrina, PR. Foram realizadas avaliações preliminares de campo, para posterior testes de confinamento e de livre escolha, em laboratório, instalados em delineamento inteiramente casualizado com três repetições. Os genótipos foram avaliados quinze dias após a infestação com uma broca por fruto em placas de petri. Os dados foram analisados pelo teste de médias Scott-Knott a 1 % e pelo teste de χ 2 . Foi observado que C. eugenioides, C. kapakata e P. bengalensis constituem importantes fontes de resistência à broca, pois apresentaram menor freqüência de grãos brocados. Os dois primeiros podem apresentar substâncias voláteis antagônicas à broca na casca e a resistência de P. bengalensis pode estar também no grão. pt_BR
