Okra (Abelmoschus esculentus) is a fruit vegetable belonging to the Malvaceae family. In Niger, the genetic diversity of okra can be a major advantage in meeting the varied preferences of consumers and the demands of national and international markets. The objective of this study is to contribute to a better understanding of the phenotypic characteristics of ten okra cultivars in Niger. The experiment was conducted at the botanical garden of the Faculty of Science and Technology at Abdou Moumouni University in Niamey using a randomized complete blocks design with three replications. Observations focused on eight quantitative traits and two qualitative traits. The results of the analyses showed significant variability among cultivars for all traits studied, except for fresh and dry weight and the effect of cultivar on the number of pods. Ascending classification allowed the cultivars to be divided into three groups. The first group (Group I), consisting of the okra long, okra short, and Tillabéry cultivars, is characterized by an early growth cycle with short stem height and diameter and average petiole length. These cultivars have high yields (high number of pods, high fresh and dry weights); the second group (Group II) is characterized by a late growth cycle with tall stems, large diameter, and average petiole length. The Gueskerou, Lada, Diffa, Sakoira, and Balleyara cultivars belong to this group and are characterized by low yield. The third group, Group III, includes the Harey Garey and Gazelle cultivars, is characterized by an early growth cycle with short stem height and small diameter. These cultivars have an average yield. This same classification made it possible to categorize the cultivars into three groups based on qualitative traits: Group I consists solely of the Tillabéry cultivar; Group II includes the Harey Garey, okra long, okra short, and Gazelle cultivars; and Group III comprises the Gueskerou, Lada, Diffa, Sakoira, and Balleyara cultivars. Five cultivars were identified for a breeding program: Harey Garey, Okra long, Okra short, Gazelle, and Tillabéry. This study provides essential information for ongoing efforts to improve productivity and study the genetic diversity of okra in Niger.
