Analisis keragaman genetik manggis (Garcinia mangostana) diiradiasi dengan sinar gamma berdasarkan penanda ISSR

Abstract

Widiastuti A, Sobir, Suhartanto MR. 2013. Genetic variability analysis of mangosteen (Garcinia mangostana) irradiated by gamma ray based on ISSR marker. Bioteknologi 10: 15-22. The aim of the research was to know the increasing of genetic variation within mangosteen based on banding pattern of ISSR marker as a response to some doses of irradiation gamma rays. Five dosages of irradiation gamma rays were 0 Gy, 20 Gy, 25 Gy, 30 Gy, 35 Gy and 40 Gy. The source of the seed that have been irradiated was from Cegal, Leuwiliang, Bogor. The results showed that gamma ray irradiation affecting mangosteen genetic changed. Because the randomize of gamma irradiation, it changed was individually. Gamma irradiation successfully increase genetic variability (5%).
