Abstract

This study aims to identify and characterize Toba bananas (Musa paradisiaca) in Parapat Village, Girsang Sipangan Bolon District, Simalungun Regency. The study was conducted from January 2025 to February 2025 using a descriptive survey method. The study was carried out in two stages. The first stage involved exploration the locations of Toba banana plants. The second stage involved identification and characterization Toba banana plants based on guidelines from the International Plant Genetic Resources Institute (IPGRI), with samples collected using purposive sampling. Based on the observation results of Toba banana samples in Parapat Village, variation were found among the samples in terms of stem color, leaf base shape, leaf vein surface color, heart shape, bract tip shape, bract outer color, pistil base shape, tepals, and the presence of flower remnants at the fruit tip, ripe fruit skin color, stem diameter, leaf blade width, number of fruits per cluster, bunch length, number of clusters per bunch, and sugar content. The coefficient of variation for all Toba banana samples ranged from 4.87 to 18.04. The dissimilarity value of the qualitative characteristics of Toba bananas ranges from 3 to 121. The combined dissimilarity value of the qualitative and quantitative characteristics of Toba bananas ranges from 7 to 146.25.
