Okra (Abelmoschus esculentus L. Moench) serves as a vegetable of great food, medicinal and industrial value. The production of the crop is, however, constrained by lack of improved high yielding, virus and pest resistant varieties. The current study sought to identify resistance in ten okra cultivars to okra mosaic disease and okra yellow vein mosaic disease within the coastal savannah agro-ecological zone of Ghana. Enzyme-linked immunosorbent assay (ELISA) detected Okra mosaic virus (OkMV) and Okra yellow vein mosaic virus (OYVMV) in symptomatic leaves of the ten cultivars. Okra mosaic disease was the most frequently detected in cultivar Adom while okra yellow vein mosaic disease was most abundant in cultivar Labadi dwarf. Mixed infection of OkMV and OYVMV was found in eight cultivars while cultivars F1-Sahari and F1-Kirene were singly infected by OkMV. The highest index of symptom severity for all plants (ISSap) was found in cultivar Kwabenya (2.80) while Togo and Adom had the least (0.30). The index of symptom severity for diseased plants only (ISSdp) varied significantly and was highest in cultivar Kwabenya (3.85). Based on disease incidence and severity, cultivars Adom, Togo, Asutem, Labadi dwarf, Kirikou-F1 and Kwabenya were rated as tolerant while F1-Sahari and Lucky-19F1 were rated as moderately susceptible. F1-Kirene and Clemson Spineless were rated as highly susceptible with disease incidence of 88.6% and 88.5% respectively.

秋葵（Abelmoschus esculentus L. Moench）品种对秋葵花叶病毒和秋葵黄脉花叶病毒抗性的评价

秋葵 (Abelmoschus esculentus L. Moench) 是一种具有食用、药用和工业价值的蔬菜。然而，由于缺乏改良的高产、抗病毒和抗虫害品种，该作物的生产受到限制。目前的研究试图确定十个秋葵栽培品种对加纳沿海大草原农业生态区内的秋葵花叶病和秋葵黄脉花叶病的抗性。酶联免疫吸附试验 (ELISA) 在十个品种的有症状的叶子中检测到秋葵花叶病毒 (OkMV) 和秋葵黄脉花叶病毒 (OYVMV)。秋葵花叶病在栽培品种 Adom 中最常见，而秋葵黄脉花叶病在栽培品种 Labadi 矮化中最常见。OkMV和OYVMV混合感染在8个品种中发现，而F1-Sahari和F1-Kirene品种被OkMV单独感染。所有植物的症状严重程度指数 (ISSap) 最高的是品种 Kwabenya (2.80)，而 Togo 和 Adom 的最低 (0.30)。仅患病植物的症状严重程度指数 (ISSdp) 变化显着，在栽培品种 Kwabenya (3.85) 中最高。根据发病率和严重程度，栽培品种 Adom、Togo、Asutem、Labadi dwarf、Kirikou-F1 和 Kwabenya 被评为耐受性，而 F1-Sahari 和 Lucky-19F1 被评为中度敏感。F1-Kirene 和 Clemson Spineless 被评为高度敏感，发病率分别为 88.6% 和 88.5%。80) 而多哥和 Adom 最少 (0.30)。仅患病植物的症状严重程度指数 (ISSdp) 变化显着，在栽培品种 Kwabenya (3.85) 中最高。根据发病率和严重程度，栽培品种 Adom、Togo、Asutem、Labadi dwarf、Kirikou-F1 和 Kwabenya 被评为耐受性，而 F1-Sahari 和 Lucky-19F1 被评为中度敏感。F1-Kirene 和 Clemson Spineless 被评为高度敏感，发病率分别为 88.6% 和 88.5%。80) 而多哥和 Adom 最少 (0.30)。仅患病植物的症状严重程度指数 (ISSdp) 变化显着，在栽培品种 Kwabenya (3.85) 中最高。根据发病率和严重程度，栽培品种 Adom、Togo、Asutem、Labadi dwarf、Kirikou-F1 和 Kwabenya 被评为耐受性，而 F1-Sahari 和 Lucky-19F1 被评为中度敏感。F1-Kirene 和 Clemson Spineless 被评为高度敏感，发病率分别为 88.6% 和 88.5%。
