Abstract

Genetic relatedness among the selected adult trees and saplings ofShorea leprosula Miq. and Dipterocarpus cornutus Dyer in two forest seed production areas (SPAs) of Compartment 17, Labis Forest Reserve, Segamat, .lohor were successfully determined via Directed Amplification of Minisatellite-Region DNA (OAMO) method by using M13, 33.6 and YNZ22 minisatellite primers. Based on Unweighted Pair-Group Method with Arithmetic Averages (UPGMA) cluster analyses, five out of 24 S. leprosula adult trees (SM1 or SM2, SM9 or SMIO, SM21 , SM24 or SM26 and SM25 or SM27) and three per 10 D. cornu/us adult trees (OM3, OM7 and OM1 0) were genetically distantly related and therefore co uld be selected as potential mother trees for quality seed production and advanced breeding programmes. The mean genetic identities of S. leprosula and D. cornutus adult trees were 0.595 and 0.508, respectively. The UPGMA cluster analyses of genetic relatedness among adult trees and saplings for both species revealed that most of the saplings were not closely related to the phenotypically selected adult trees; therefore the existing saplings within the seed stand should not be selected as planting materials for forest plantations.
