ANALISIS FENETIK TANAMAN KARET (Hevea brasiliensis (Willd. ex A. Juss) Mull. Arg.) BERDASARKAN PENANDA ISOZIM DI LIMA KABUPATEN SENTRA PERKEBUNAN KARET RIAU
Abstract
Many kinds of rubber plants (Hevea brasiliensis (Willd. ex A. Juss) Mull. Arg.)
has been cultivated in Riau Province. Phenetic analysis of rubber plants can give
information about their relationship. Study to obtain information about the relationship
among rubber plants which are grown in 5 rubber plantation centers in Riau was
conducted based on isozyme markers. A total of 15 trees had been studied. The samples
were taken from 5 regencies i.e. Bengkalis, Meranti, Kuantan Singingi, Kampar, and
Rokan Hulu using an exploration method. Four enzymes (PER, EST, ACP, and AAT)
were used for similarity and clustering analysis using NTSys program version 2.02. The
result of this research showed 19 polymorphic bands, 9 bands from PER, 5 bands from
EST, 2 bands from ACP, and 3 bands from AAT enzyme. The similarity analysis of 15
individuals showed that the similarity coefficient ranged from 0.47-1. The clustering
result showed that all of individuals were grouped at the coefficient of 0.59. Most of the
samples were grouped together based on the band similarity. However, all of samples
collected from Bengkalis, as well as Kuantan Singingi, formed a cluster due to the high
band similarity.
