Karakteristik genotipe hibrida hasil persilangan 3 strain ikan nila Oreochromis niloticus dengan metode Random Amplified Polymorphic DNA (RAPD)

Abstract

Objectives of this study were to observe the genetic variability and relationship among hybrids of three strains (BEST, Nirwana, and Red NIFI) using Random Amplified Polymorphic DNA (RAPD). The results showed that hybridization enabled to increase genetic variability respectedly on progeny between male Nirwana with female BEST (27.93%) as well as between male Nirwana with female Red NIFI (27.23%). Based on relationship analysis there were indication that Nirwana and Red NIFI were closer to the hybrid groups, compared to BEST one. The greatest genetic distance was the hybrids of Nirwana x BEST (0.6).
