Early Identification of Genetic Diversity and Distance from Indonesia Cassava Potential as Food, Industrial and Biofuel Based on Morphological Characters

Diversity and genetic distance are required as initial foundations to identify germplasm Indonesian cassava potential for food, industrial, and biofuel resources. This study used 181 cassava (Manihot esculenta Crantz.) accessions from all islands in Indonesia, i.e. Java, Sumatera, Kalimantan, Sulawesi, Maluku, Nusa Tenggara Timur and Papua Islands. The study was conducted in July 2013 to March 2014. Research experiment design was arranged in Augmanted Design with three control plants per row. There were traits of morphological rod and leaf as parameter, the number of 19 traits. The analysis was using Principal Component Analysis (PCA) and Agglomerative Hierarchical Clustering (AHC). Results of this study are genetic diversity and distance cassava from Indonesia with a wide diversity level of 49.82% and from 1 to 17 genetic distance spread throughout Indonesia.
