Identification morphological variability of six mangosteen (Garcinia mangostana L.) As a conservation strategy for local varieties

Morphological traits of six Mangosteen varieties were observed for two years from 2017 to 2019. This research aims to determine the growth and fruit characters of six mangosteen varieties in IP2TP Subang. The study was conducted in a randomized block design with 6 varieties: Kaligesing, Puspahiyang, Wanayasa, Ratu Kamang, Ratu Tembilahan, and Lingsar as a treatment and repeated 5 times. Each treatment unit is comprised of 6 trees. The observed characters comprised growth characters, leaf characters, and fruit characters. The results showed that the growth of several mangosteen varieties tested in relatively the same environmental conditions was quite varied, especially in the character of plant height and stem perimeter. Leaf character varied in leaf shape. Fruit characters also varied, especially characters fruit weight and plant with fruit. Ratu Tembilahan variety was the most adaptive variety because it had the highest growth ability and the highest fruit production.
