Nurmiyati, Sugiyarto, Sajidan. 2009. Kimpul (Xanthosoma spp.) characterization based on morphological characteristic and
isozymic analysis. Nusantara Bioscience 1: 138-145. This research is aimed: (i) to know the variety of kimpul (Xanthosoma spp.) based
on morphological characteristics and isozymes analysis; (ii) to know the correlation between its genetic space based on morphological
characteristics and its genetic resemblance based on isozymes-banding pattern. This research results were analyzed and described by
descriptive qualitative methods. Morphological observation was carried out in sub-District of Galur, Lendah and Girimulyo, Kulonprogo
District, Yogyakarta. Morphological data of the kimpul plant was explored descriptively and then made dendogram. Data of isozymic
banding pattern were analyzed quantitatively based on the appearance of the band on the gel, and qualitatively based on the thickness of
the band formed, and then made dendogram. The correlation, between its genetic distance based on morphological characteristics and its
genetic resemblance based on isozymes-banding pattern, were then analyzed grounded on coefficient correlation between product-
moment and goodness of it criteria based on correlation. The results pointed out that morphologically, on eight observed samples which
were consist of four different types (species), each Xanthosoma from different locations did not indicate obvious differences. Esterase
was formed four different banding-patterns, Glutamate Oxaloacetate Transaminase indicated eight different banding-patterns, and
Peroxidase indicated seven different banding-patterns. Correlation between morphological data and data from EST and GOT isozymic
banding pattern were very good (0.967918 and 0.937113), While, the correlations between morphological data and POD isozymes were
good (0.892721).
