A study on indicator seedling quality on survival rate and growth of red meranti species were conducted at concession holder PT Sari Bumi Kusuma (PT SBK) Central Kalimantan and PT Itci Kayan Hutani (PT IAKNI), East Kalimantan. The purpose of this research to get information seedling quality on survival rate and the growth of red meranti, priority of silin program after planted one year in the field. Treatments consisted of three species and three seedling quality class from wildling in PT SBK and two species and three seedling quality class from wildling in PT IKANI. Factorial completely randomized block design with four replications was used for this study.Before seedling planted in the field, the seedling were selected based on seedling quality class based on height, diameter, value strength and top root ratio in nursery. Each treatment consisted of 100 plants were planted with 10 m x 2.5 m spacing. The total number of plants observed as much as 3.600 plants and 2.400 plants respectively. The result showed that species, seedling quality, interaction between species and seedlings quality and block did not significant effect on the survival rate in both concession holders. But in both concession holder that species and seedling quality gave significant different on height and diameter growth. The height and diameter growth of S. leprosula was higher than other species as much as 146.6 cm and 1.6 cm, respectively in PT SBK and in PT IKANI as much as 86.5 cm and 0.8 cm respectively. Based on SNI 01-5005.1-1999 seedling quality class one and two for meranti had given better growth and survival rate compared than seedling quality class three. Therefore S. leprosula from wilding with seedling quality class one and two in SNI 01-5005.1-1999 are recommended for planting in Silin program with Selective Cutting and Planted Indonesia Intesif System.
