Morphological characterization of local durian of Banten Province, Indonesia

Abstract

Abstract Durian (Duriozibethinus) is an exotic fruit with relatively advanced varietal improvement prospects. Indonesia is one of the countries with high durian diversity, one of which is located in Banten Province. This study aims to determine the diversity and relationships of several local durians in Pandeglang and Lebak Regencies of Banten Province based on the morphological characters of leaves, flowers, and fruit. The durian samples were obtained by purposive sampling and interview methods. The morphological characterization was carried out according to the guidelines of the “Bioversity International” including the description of stems, leaves, flowers, fruits, and seeds. After the characterization, scoring, standardization, and similarity index (IS) were calculated between samples. Cluster analysis was carried out using Cluster Observation with Ntsys 2.0 software. The analysis was conducted on 50 characters in 20 local durian accessions. The results showed that the clustering analysis was divided into three clusters with a similarity coefficient of 0.64. Group I consisted of SangkanWangi 2. Group II consisted of Hauk, Ketan Jaya, Grinsing, Sikucing, Kadu Katung, Jangkung, Sibening, Siradio, Siceer, Sipedang, Sikempong, Sicayut, and Sijabrig. Meanwhile, Group III consisted of Siemas, Baranjang, Kaduhejo, Kadukuning, Sangkan Wangi 1, and Sibening.
