Identifikasi Karakter Morfologis dan Hubungan Kekerabatan Beberapa Genotipe Tanaman Kelapa (Cocos mucifera L.) di Kabupaten Aceh Selatan Provinsi Aceh

Abstract

This study aims to identify morphological characters and phylogenetic relationships of several genotypes of coconut (Cocos nucifera L.) in Bakongan District, East Bakongan District, and South Kluet District, South Aceh Regency, Aceh Province. This research was conducted from June to July 2022 using descriptive survey method based on coconut descriptor of International Plant Genetic Resources Institute (IPGRI) with sampling technique using accidental sampling technique. The results showed that in South Aceh District 27 genotypes of coconut been identified. The results of the morphological characteristics of coconut plants found in general are the shape of the crown X "silhouette", upright stem growth pattern, the color of the leaflets is green, the color of the petiole is yellowish green, the type of flowering is normal and the shape of the fruit is elbow-shaped and yellow. The closest phylogenic relationship or lowest dissimilarity value is found in genotypes BK2S2 and BK2S3, which is 15,109%. The farthest phylogenetic or highest dissimilarity value is found in genotypes BK1S1 and KT1S1, which is 115,630%.
