Type and Morphological Character of Local Cloves (Syzygium aromaticum (L.) Merr. & L. M. Perry) from North Maluku Province, Indonesia
Abstract
The North Maluku Province is renowned for being the original region where clove distribution started. This region comprises several island groups with high clove diversity. The research aimed to investigate and to recognise the morphological diversity of local cloves in North Maluku Province. The study employed a survey method, which included exploring six islands, namely Ternate, Tidore, Halmahera, Moti, Bacan, and Kasiruta, and led to the discovery of 13 local clove accessions. These accessions are Afo, Zanzibar Merah, Sikotok, Siputih, Rica, Maluku, “Gagang Panjang” clove, Sibela I, Sibela II, Forest Clove, White Zanzibar, Bogor clove, and “Biasa” clove. Based on Hierarchical Cluster Analysis (HCA), all clove accessions were morphologically characterised and classified into two groups with a dissimilarity coefficient of 49 %. The first group is the cultivated type of cloves that consists of local Afo cloves, Sibela I, Sibela II, Siputih, Sikotok, Rica, Red Zanzibar, “Gagang Panjang” clove, White Zanzibar, Bogor cloves, “Biasa” cloves, and Maluku cloves. On the other hand, the second group is the wild-type clove group, namely Forest Cloves . The characteristics of local clove accessions based on Principle Component Analysis (PCA) showed a total diversity of 52.5 %.
