【 摘 要 】

The research aims to study of flower morphology of G. atroviridis plants in several Districts of North Sumatera. This study was conducted in Asahan, Batubara and Serdang Berdagai districts in February to April 2017, exploration using survey method with IPGRI descriptors guide, and accidental sampling. The research results showed that in three Districts of Sumatera Utara, there are 26 accessions of Asam Gelugur characterized based on morphology of flowers. Based on clustering analysis using the NTSYS-pc Program, all flower morphology data resulted in dendogram with similar coeffisien range from 0.34 to 0.75 into four groups. The first group (I) consists of 16 accessions i.e Asahan, Batubara and Serdang Bedagai districts. The second group (II) in Asahan, Batubara and Serdang Bedagai districts there are 7 accessions The third group (III) consists of two accessions, i.e. Asahan and Batubara Districts.
