Amorphophallus muelleri blume diversity based on morphological characteristics in South Sulawesi

Abstract Porang is an alternative carbohydrate source plant that contains the highest glucomannan among other Amorphophallus species in Indonesia. Amorphophallus muelleri Blume is an important species of the genus Amorphophallus, which belongs to the same subspecies A. bulbifer and A. yuloensis. A. muelleri Blume has good disease resistance and heat tolerance tendency, and high KGM content. Kinship relationships can be used as a basis for assembling more potential genotypes. To find out the kinship between existing varieties we must exploration and identify. This research was carried out using qualitative methods analysed in the numerical taxonomy and multivariate analysis system version 2.02i (NTSYS) program. The genetic materials used in this study were explored from wild growing habitat in agroforestry areas in South Sulawesi, Indonesia. The results obtained that the MR6 and BL10 genotypes which had a similarity coefficient value of 1.00, between genotypes MR4, MR9, MR10, BT4 and BT10 had a similarity coefficient value of 1.00, between genotypes BT5 and BT7 have a similarity coefficient value of 1.00, and between genotypes BT1, BT2, BT9 have a similarity coefficient value of 1.00. Furthermore, BL1, BL4, and BL6 contribute significantly of the variation as showed by PC1.
