The most seriouse affecting Sengon (Sengon (Falcataria moluccana) plantation is Gall rust is coused by the fungus Uromycladium tepperianum (Sacc.) McAlp. This disease reduced the yield due to mortality and stems brakage (fllowing the formation of stem-girdling galls) reduced marketability and decreased of ghrowth rates. This research aimed to select seedlings sengon which is tolerant to gall rust disease at provenence level, Five seed sources were used for this study i.e. from Papua (Elaigama Hubikosi and Siba Hubikosi) and Java (Candiroto, Kediri and Wonosobo).
