The genus Solanum exhibits a wide range of variability in morphology, flavor, and tolerance to biotic and abiotic stresses. Phenotypic and genetic variability using ISSR and RAPD markers of Solanum incanum distributed in Al-Baha province of the Kingdom of Saudi Arabia is assessed. Thirty samples are representing three different locations: Baljershy, Aqeeq, and Tohama, besides twenty-five samples representing five different commercial cultivars tested. Growth type, the number of leaves per plant, fruit size (phenotypic traits), crude protein, carbohydrates, digestive organic matter, and Mg, Ca, P were the principal contributors in the PCA. Molecular analysis showed that 114 ISSR and 80 RAPD alleles with a 100% polymorphism were recorded. The polymorphism information content (PIC) values ranged from 0.84 to 0.91 for ISSR and from 0.59 to 0.89 for RAPD data. Similarity values ranged from 0.16 to 1.00, with an average of 0.47 for ISSR and from 0.01 to 0.97, with an average of 0.36 for RAPD. It resulted in a positive and significant correlation between morphological, molecular, nutritional, and chemical analysis of fruits using Mantel analysis. UPGMA and PCA for morphological traits and molecular data discriminated commercial cultivars and wild relatives. Solanum incanum was more diverse than commercial varieties. This study revealed a wide genetic diversity among and within collected eggplant accessions and may use in breeding programs of eggplants. There is a need to increase the present eggplant collection to widen the genetic diversity of cultivated eggplant varieties in Saudi Arabia.

茄属在形态、风味和对生物和非生物胁迫的耐受性方面表现出广泛的变异性。使用茄属植物 ISSR 和 RAPD 标记的表型和遗传变异性分布在沙特阿拉伯王国的巴哈省进行了评估。30 个样本代表三个不同的地点：Baljershy、Aqeeq 和 Tohama，此外还有 25 个样本代表测试的五种不同的商业品种。生长类型、单株叶片数、果实大小（表型性状）、粗蛋白、碳水化合物、消化有机质和镁、钙、磷是 PCA 的主要贡献者。分子分析表明，114个ISSR和80个RAPD等位基因的多态性为100%。ISSR 的多态性信息内容 (PIC) 值范围为 0.84 至 0.91，RAPD 数据的范围为 0.59 至 0.89。相似度值范围为 0.16 到 1.00，ISSR 平均值为 0.47，RAPD 平均值为 0.01 到 0.97，平均值为 0.36。它导致使用 M​​antel 分析的水果的形态、分子、营养和化学分析之间存在显着的正相关。用于形态特征和分子数据的 UPGMA 和 PCA 区分了商业品种和野生近缘种。Solanum incanum比商业品种更多样化。这项研究揭示了收集的茄子种质之间和内部的广泛遗传多样性，并可用于茄子的育种计划。有必要增加目前的茄子收集，以扩大沙特阿拉伯栽培茄子品种的遗传多样性。
