KERAGAMAN GENETIK TETUA DAN ANAKAN DARI KEBUN BENIH SEMAI Acacia mangium GRUP D (AM004) DI SUMATERA SELATAN, INDONESIA
Abstrak: Information on genetic
diversity from one generation to its next generation is an important factor for
management and conservation in a seed orchard. The purpose of this study was to
evaluate the level of genetic diversity of parental as the first generation
(F1) and offspring (F2) of Acacia mangium in the A. mangium seed orchard Group
D (AM004) in South Sumatera. Analysis was conducted on 251 parental trees and ±
200 seeds from 10 mother trees. Analysis using 12 microsatellite markers showed
that mean number of detected allele (A) for all the parents and offspring was
8.23 and 7.08, repectively. In general, the level of genetic diversity in
parental and its offspring was not different (He=0.609 for parental and
He=0.606 for offspring). The presence of new alleles that was detected from
offspring indicated the possibility of pollen contamination from outside the
seed orchard.
