This result of research showed that in tree North Sumatera district there were 21 accession of asam gelugur been identified. The result of morphologycal characteristics for crown shape (pyramidal and elliptic), trunk surface (smooth, rough, very rough), leaf shape (elliptic, oblong, lanceolate), flower shape (female flower and hermaphrodite flower), fruit shape (round, flattened, ovoid).
