Abstract

The Tanimbar Islands in Maluku Province, Indonesia, are a significant distribution center for Dioscorea alata L. However, exploration and morphological characterization of this species remain limited. This study aimed to (1) identify and analyze the morphological characteristics of local D. alata from the Tanimbar Islands and (2) determine the distinguishing characteristics for each D. alata accession observed. The exploration of D. alata was followed by ex-situ cultivation. Morphological characterization was conducted on 15 accessions using 16 morphological traits based on the International Board for Plant Genetic Resources (1997) descriptors. Hierarchical Cluster Analysis (HCA) revealed two primary groups with a dissimilarity coefficient of 33%. Group one consisted of the DA-01 and DA-02 accessions, while all other accessions formed group two. Notably, accession DA-11 within group two displayed a 26% difference in morphological traits compared to other group members. Principal Component Analysis (PCA) identified 21 significant characteristics that contributed to 42.9% of the total diversity. Accession DA-01 exhibited unique characteristics such as tuber cracking, while DA-02 stood out for stem diameter and leaf width. Additionally, DA-13 displayed unique root positions on the tuber surface, DA-14 exhibited distinctive leaf apex coloration, and DA-15 showed a unique inner tuber skin color. This study underscores the morphological diversity of D. alata in the Tanimbar Islands, providing valuable insights into its genetic resources.

印度尼西亚马鲁古塔宁巴尔群岛当地山药的勘探和形态特征描述

印度尼西亚马鲁古省的塔宁巴尔群岛是薯蓣（Dioscorea alata L.）的重要分布中心，但对该物种的探索和形态特征描述仍然有限。本研究的目的是：（1）鉴定和分析塔宁巴尔群岛当地 D. alata 的形态特征；（2）确定所观察到的每个 D. alata 品系的区别特征。在对 D. alata 进行勘探后，又进行了异地栽培。根据国际植物遗传资源委员会（1997 年）的描述符，利用 16 个形态特征对 15 个品种进行了形态特征鉴定。层次聚类分析（HCA）显示有两个主要组别，相似系数为 33%。第一组由 DA-01 和 DA-02 两个品种组成，所有其他品种组成第二组。值得注意的是，第二组中的 DA-11 与其他组员相比，形态性状差异达 26%。主成分分析（PCA）确定了 21 个显著特征，占总多样性的 42.9%。样本 DA-01 表现出独特的特征，如块茎开裂，而 DA-02 则在茎直径和叶宽方面表现突出。此外，DA-13 表现出块茎表面独特的根部位置，DA-14 表现出独特的叶顶着色，DA-15 表现出独特的块茎内表皮颜色。这项研究强调了塔宁巴尔群岛 D. alata 的形态多样性，为了解其遗传资源提供了宝贵的资料。

期刊介绍： Genetic Resources and Crop Evolution is devoted to all aspects of plant genetic resources research. It publishes original articles in the fields of taxonomical, morphological, physiological, biochemical, genetical, cytological or ethnobotanical research of genetic resources and includes contributions to gene-bank management in a broad sense, that means to collecting, maintenance, evaluation, storage and documentation. Areas of particular interest include: -crop evolution -domestication -crop-weed relationships -related wild species -history of cultivated plants including palaeoethnobotany. Genetic Resources and Crop Evolution also publishes short communications, e.g. newly described crop taxa, nomenclatural notes, reports of collecting missions, evaluation results of gene-bank material etc. as well as book reviews of important publications in the field of genetic resources. Every volume will contain some review articles on actual problems. The journal is the internationalized continuation of the German periodical Die Kulturpflanze, published formerly by the Institute of Plant Genetics and Crop Plant Research at Gatersleben, Germany. All contributions are in the English language and are subject to peer reviewing.
