Conservation of wild nutmeg (

The population of wild nutmeg ( Myristica spp) in Halmahera, North Maluku, represents an important genetic resource requiring conservation to preserve the germplasm of this economically valuable spice plant. Limited morphological data may hinder its optimal utilization. This study identifies morphological diversity as the basis for conserving wild nutmeg accessions growing naturally in Halmahera forests, using 20 morphological markers measured on fruit, seed, leaf, and mace characters. Descriptive analysis, ANOVA, and cluster analysis revealed significant phenotypic variation. The Wayamli accession has larger fruit and leaf sizes, while the Patani accession shows distinctive seed shapes and thinner mace. These findings confirm ecological differentiation and highlight the importance of morphological markers in germplasm conservation. Furthermore, conservation strategies are linked to climate change mitigation and adaptation, positioning wild nutmeg as a biodiversity resource that supports carbon sequestration, ecosystem resilience, and sustainable agroforestry development.
