Gelam (Melaleuca cajuputi subsp cumingiana), is one of the endemic species that is under threat. A conservation plot was developed in the Banyuasin regency. It was designed as Gelam’s genetic conservation area and seed producing area in the near future. The plot was developed in Randomised Completely Block Design and consisted of 60 families, collected from Banyuasin and Bangka regency. It was stretched for 5 tree plots, 6 blocks, and 3x3 m of spacing. A preliminary study has been taken to record and evaluate Gelam’s growth over its genetic variation. It was shown that the survival of the species might vary (23% to 90%) with the population collected from Banyuasin performing a slightly better average. Further, the growth variation did not significantly differ between the two origins while the families affect performed significantly. The family heritability of the growth was moderate for height (h2f = 0.60) and low for diameter (h2f = 0.25) while its genetic correlation was strong (0.76). Through adequate technical support and suitable development strategy, this plot can be designed to provide the improved seed to boost degraded peatland rehabilitation in the region.

“…To meet the challenges, we develop provenance conservation plot in KHDTK Kemampo, Sumatera Selatan. The material were collected from two natural populations of Gelam in Bangka and Banyuasin [13]. From this site, we expect to deliver seeds that has superior characteristics.…”
