Susceptibility Provenances of Falcataria moluccana to Gall RustDetermined by Disease Incidence and Severity

ABSTRACT

During 2003-2009 plantations of F. moluccana in Java, had been attacked severely by gall rust disease, which caused the slump of F. moluccana wood production. Therefore, selection of gall- rust resistance of F. moluccana should be undertaken, in order to reduce the gall rust impact. Observation to determine the provenances which had less susceptibility to gall rust disease were carried out at nursery level in the glass house of Forest Biotechnology and Tree Improvement Research Centre, Yogyakarta and at 3-years old of F. moluccana resistance trial at Kediri, East Java. The disease severity and incidence in the nursery level varied significantly between provenance samples, which provenance from Wamena (Papua) exhibited least susceptible to gall rust compared to provenance from Java. Provenance form Wamena (Papua) demonstrated the average disease severity of 16,7 % and disease incidence of 10,6%. Meanwhile, the average disease severity and disease incidence provenance from Java showed 86% and 94%. These results consistent with results in the plantation trial, which revealed trees from Papua exhibited the lowest threat of gall rust indicated by the low average of disease severity and incidence compared to trees from Java and Lombok provenances.
