【 摘 要 】

The objectives of this research was to identify and create database about the diversity of local yellow and orange sweet potatoes accessions in Sumatera Utara, have diversity accession local sweet potatoes genotype in Sumatera Utara selection for classifying populations get high production and good fruit quality. The experiment was conducted in areas of production centers of sweet potatoes in the exploration survey methods in 2 districts in Sumatera Utara, which is in the Kabupaten Simalungun and Dairi. The study was conducted on June to July 2017. Observations were made based on the identification and characterization Description List of International Board for Plant Genetic Resources standard and purposive random sampling technique. The result of this research indicate there 15 genotype of sweet potato yellow and orange in KabupatenSimalungun consistedof KecamatanPurba (G3, G4 and G7), Silimakuta (G5, G6 and G14), and Pamatang Silimahuta (G15) in Kabupaten Dairi consists of Kecamatan Parbuluan (G1, G2, G8 and G9), Sidikalang (G10 and G13), Sumbul (G11), and Sitinjo (G12) with nearest relationship is G13 and G15 with a coefficient similarity 23.908 and farthest relationship is G2 and G7 with a coefficient similarity 140.029.
