The Mangosteen (Garcinia mangostana L.) is an economically important fruit in Malaysia but the species and most Malaysian members of the genus are understudied. Full morphological descriptions of most of the species are still not complete. The genus possesses an apomictic mode of reproduction which is an important factor in plant breeding and seed production in agriculture. The aim of the present study is to observe polyembryony in G, mangostana, to classify the Malaysian Garcinia into sections, to look at the genetic variation and relate it to apomixis, and finally to identify the parents of G. mangostana.
