Permatasari, Pitoyo A, Suratman. 2014. Keragaman suweg (Amorphophallus campanulatus) di wilayah eks karesidenan Surakarta berdasarkan karakter morfologi, anatomi dan pola pita isozim. Bioteknologi 11: 11-18. The aims of this research were to find out the diversity and relationship among elephant yam in Surakarta region based on variation of morphological, anatomical and isozyme banding patterns characters. Total 20 samples were taken using random purposive sampling technique in different altitude of 7 districts. Morphological, anatomical and isozyme banding pattern data were analyzed descriptively. The steady data of quantitative characteristic from morphological, anatomical and isozyme banding pattern of binary data was analyzed using an Index of Similarity (IS) and computed by the program Numerical Taxonomy and Multivariate Analysis System (NTSYS) version 2.10. The result showed that the elephant yam in Surakarta region were diverse based on morphological, anatomical and isozyme banding pattern, especially in ratio and color of petiolus; tuber ratio; index of stomatal; thick epidermis; thick mesophyll; term and ratio of palisade; term rafida; 4 peroxidase and 5 esterase isozyme banding pattern. Analysis of relationship of elephant yam based on morphological, anatomical and isozyme band pattern characters showed the similarity coefficient of 64,85% contained two major group. The first group consist of Boyolali 1, Boyolali 3, Boyolali 4, Wonogiri 4, Wonogiri 2, Karanganyar 1, Karanganyar 2, Karanganyar 3, Sragen 2, while the other samples were separated from this group.
