ABSTRACT
The present work aimed at evaluating the resistance reaction to pest and disease of introduced species and local clones of Salix x rubens, in different ecosystems of “Planalto Serrano Catarinense”. Three experiments were conducted in field conditions during 2003/2004 crop cycle with introduced genotypes from Argentina, Chile, Germany and France and local clones of Salix x rubens. The resistance evaluations consisted of pest incidence and severity of leaf diseases estimations. A rank of resistance reaction of willow was demonstrated as result of large genetic base. The research showed that genotypes EEL_10, EEL_08, EEL_02, EEL_13, EEL_09, and EEL_20 access were the most resistant ones against pest and diseases. Further studies would be needed to verify if these genotypes can be suitable for crafting when cultivated in the “Planalto Serrano Catarinense” conditions.
