Abstract: The genetic potential of different plant species to different environmental conditions differ in relation to different physiological, biochemical and anatomical characteristics. Of these varying attributes leaf anatomical characteristics play most important role for the establishment of that cultivar in varied environmental conditions. So, the present study was conducted to assess the inter-cultivar genetic potential of Hibiscus in relation to leaf anatomical characteristics.  To fulfill the study requirements Hibiscus rosa-sinensis and its six cultivars (were well adapted to their specific natural habitat) were collected from different locations of district Faisalabad Pakistan that have great environmental changes round the year. Results showed significant variability among cultivars in relation to analyzed anatomical characteristics. Cultivars Lemon shiffon and Wilder’s white emerge more promising among others by possessing more epidermal thickness, increased epidermal cell area, high cortical cell area and incremented stomatal density as compared with other cultivars. On the other hand, cultivars Cooperi alba, Mrs. George Davis and Frank green possessed least cortex cell area, lowest xylem region thickness and minimum phloem region thickness respectively. Overall, it can be concluded that anatomical genetic potential has endorsed cultivars Lemon chiffon and Wilder’s white with enormous capability to grow well under variable environments.
