dc.description.abstractThe oomycete Pythium myriotylum is an important pathogen of several crops, causing wilt and damping-off during nursery propagation. The pathogen was recently reported as the causal agent of wilt and damping-off on Acacia crassicarpa plants in nurseries located in Riau, Indonesia. The aim of this study was to evaluate the relative pathogenicity of P. myriotylum on different clones of A. crassicarpa and Acacia mangium × Acacia auriculiformis hybrids. Based on the results, greater tolerance was found on the A. mangium × A. auriculiformis hybrid clones than on those of pure A. crassicarpa. The different Acacia clones also displayed different levels of tolerance of infection. Overall the results showed that screening for tolerance to infection by P. myriotylum will be important in the Acacia breeding programme and make it possible to produce sufficient nursery stock for plantation establishment.
