ABSTRACT

Objectives of the study was to discover genetic variability and genetic relationship of paternal half sib population of nile tilapia (Oreochromis niloticus) under Selection Program Scheme at Research Institute for Freshwater Aquaculture, in Bogor, West Java. Four populations from unrelated selected breeders were observed for genetic variability using RAPD. The analysis of amplification from each locus and fragments were used to estimate DNA polymorphisms, heterozygosity, fst and genetic distance. The range of heterozygosity of four examined populations was 0.1760–0.2168 with level polymorphic between 47.66% and 64.86%. The highest heterozygosity and polymorphic was on population 1 and the lowest one was on population 2. Fst test showed significance among the populations. The closest relationship was between population 1 and 4 (0.1978) and the furthest was population 2 and 3 (0.3289).
