The research conducted to investigate genotype � environment interaction at the second generation (F2) of Acacia mangium Breeding Seed Orchard (BSO) in four locations: Lipatkain (Riau, Sumatera), Tanjung Redeb (East Kalimantan), Kenangan (East Kalimantan) and Pelaihari (South Kalimantan). The BSO-s have established by using 51-55 families taken from Group B and designed by RCBD, 4 tree plot, spacing 4 x 2 m and 8 � 10 blocks. Growth of 36 month old of trees from the same families in all location (31 families) have analyzed in height, diameter and volume. Multi location analyses of variance showed that the component of genotype � environment interaction (s 2 fl) very significant. Ratio (s 2 fl / s 2 f) for height, diameter and volume about 1,239
