Progency analysis of the tasikmalayan mangosteens (Garcinia mangostana) with e-RAPD markers

Abstract

Apomixis is an asexual mode of plant reproduction through seeds without fertilitation. A common feture of all apomics is the autonomous development of embryos and the generation of progenies that are the exact genetic replicas of the mother plant. The aims of apomixis study are to unlock the diversity of the apomictic plants and to know the incidence of the apomixis in the mangosteens and the description of the inheritance genetic pattern of the progenitors to their progeny. The genetic varablities within the population are Salawu (5-14%), Puspahiang (9-25%), Tanjungjaya (10-25%), and Sukaraja (22.5-29.6%), and among the population 30-47% variability. However, 100% of genetic similarity values gave by Salawu8 progenitor with Salawu8 progeny-1, and Puspahiang progeny-2 and progeny-3. Meanwhile, the other accession have 71.4-98% similirity. E-RAPD were succesfully applied to the analysis of apomixis in the different progeny population of mangosteens.
