ANALISIS HUBUNGAN KEKERABATAN MACANG (Mangifera foetida Lour.) DI SUMATERA BAGIAN TENGAH

Abstract

The diversity of Mangifera foetida Lour. (macang) in central Sumatra has not been explored and inventoried. On the other hand, the diversity of cultivars and varieties of this species is endangered due to the lost of its natural habitat. This research aimed to analyze the diversity of macang in central Sumatra. The research was carried out from December 2011 to June 2013. The morphological and agronomical characters of a total of 66 macang trees had been observed. All of these observed characters were then scored and analyzed using NTSYSpc 2.02 to determine their clustering and using Minitab to analyze the principle component and correlation of Pearson. The result showed that the similarity coefficient ranged from 0.17 to 0.76. Dendogram constructed from the similairty coefficient showed two main groups, that clustered not based on the sample locations but based on the character similarity (fruit color). The first group consisted of 65 individuals and second group consisted of one individual. The result of Principle component analysis showed two main groups, with the diversity accumulation value was 40%. The results of correlation analysis of 66 characters showed that six characters were positively corellated
