<b>Background and Objective:</b> Considering that the potential for okra as an anti-diabetic is very high, while okra productivity in Indonesia is still low, a plant breeding program through variety development is needed. One of the initial activities that needs to be carried out is the characterization of various genotypes, both quantitative and qualitative characters. This research aimed to obtain information on the diversity of morpho-agronomic characters in okra genotypes. <b>Materials and Methods:</b> The experiment was conducted as a randomized block design, one factor is genotype with three replications. The materials used in this research were 20 okra genotypes. The experimental units used in this research were 60 units. Each experimental unit consists of 10 sample plants. Analysis of quantitative character variations used PKBT-STAT 3.1. Cluster analysis was carried out with PBSTAT-CL 2.1.2 with the Gower dissimilarity and average linkage clustering methods. Furthermore, analysis was carried out using SAS OnDemand for Academics to see the distinguishing characteristics between clusters. <b>Results:</b> There were differences in okra genotypes based on qualitative and quantitative characteristics. The most diverse quantitative character is the yield component, which is the fruit character. Variance in genetic and heritability showed broad and high criteria, respectively. Based on cluster analysis results, okra genotypes were grouped into 3 clusters with a cophenetic distance value of 0.40. Cluster 1 consists of 9 genotypes. Cluster 2 consists of 10 genotypes. Cluster 3 consists of 1 genotype the Red Hill Country genotype. The grouping in cluster analysis was carried out based on leaf width, number of fruits, fruit weight, fruit diameter and carpel thickness character. <b>Conclusion:</b> This diversity of okra germplasm can facilitate plant breeding activities in the future by selecting genotypes to serve as parents according to the objectives carried out.
<b>背景与目的：</b>鉴于黄秋葵作为抗糖尿病药物的潜力非常高，而印度尼西亚的黄秋葵产量仍然较低，因此需要通过品种开发进行植物育种计划。需要开展的初始活动之一是对各种基因型进行特征描述，包括数量和质量特征。本研究旨在获得有关黄秋葵基因型形态农艺学特征多样性的信息。<b>材料与方法：</b>试验采用随机区组设计，一个因素是基因型，有三个重复。本研究使用的材料是 20 个黄秋葵基因型。本研究使用的实验单位是 60 个单位。每个实验单位由 10 个样本植物组成。数量性状变异分析使用 PKBT-STAT 3.1 进行。聚类分析使用 PBSTAT-CL 2.1.2 进行，采用戈氏不相似性和平均连锁聚类方法。此外，使用 SAS OnDemand for Academics 进行分析，以查看聚类之间的区别特征。<b>结果：</b>根据定性和定量特征，黄秋葵基因型存在差异。产量构成是果实特征，是最具多样性的数量性状。遗传方差和遗传力表现出广泛和高的标准。根据聚类分析结果，黄秋葵基因型分为 3 个聚类，协方差距离值为 0.40。聚类 1 由 9 个基因型组成。聚类 2 由 10 个基因型组成。聚类 3 由 1 个基因型组成，即 Red Hill Country 基因型。聚类分析中的分组是根据叶宽、果实数、果实重量、果实直径和心皮厚度特征进行的。<b>结论：</b>这种黄秋葵种质资源的多样性可以通过选择基因型作为目标活动的亲本来促进未来的植物育种活动。
