Jati Plus Perhutani (JPP) is a fast growing teak ( L.f.) species that has been developed since 20 years ago by Research and Development Center of Perum Perhutani through a serial program of tree improvement. At the same age, stem diameter of this superior teak tree is larger than that of the conventional teak. However wood behavior during kiln drying has not been much studied. This study examined drying property and quality of 5, 7 and 9 year old of JPP woods in relation to their wood basic properties Results showed that basic properties of JPP wood are inferior compared than those of conventional teak wood. Drying property and quality are affected significantly by cell wall thickness, juvenile wood portion, heartwood-sapwood percentage, MFA, initial moisture content, wood density and specific gravity, as well as growth stresses. Compared to those of conventional teak wood with similar in diameter (older tree), drying quality of JPP wood until 9 year-old was still poor and unfavorable. Based on the drying quality and specific condition of the JPP wood, the minimummaximum drying temperature was around of 30-40°C for 5 year-old, 40-50°C for 7year-old and 40-60°C for 9 year-old
