- Morphological characterization have great role for identification of different mango (MangiferaindicaL.) cultivars. Mango is perennial crop having long juvenile period and it is very difficult to identify a cultivar at theinitial stages of growth. Proper morphological leaf characterization can overcome these difficulties. This study was performed to identify mango cultivars in Sudan based on their leaf morphology. Leaves were collected in triplicate representing 30 cultivars Sixteen cultivars were grafted genotypes of Indian or Egyptian origin, 11 cultivars were grown directly from seeds (Balady) and 3 cultivars imported recently from South Africa. descriptors were used in the study. Comparisons between means were made by least significant differences (LSD). The result Showed a high diversity of mango genotypes and cultivars. There were great variations in leaf length, width and petiole length with significant (P> 0.05) differences between the genotypes and cultivars in each genotype. Seedling cultivars showed longer leaves ( 0.5) between the three genotypes but not between cultivars in each of them. Seedling cultivars have lanceolate leaf blade shape, 63% of them with acute leaf apex shape with obtuse , acute or round leaf blade shape. Grafted cultivars vary greatly in their leaf blade shape with most of them having acuminate apex Shape and acute or obtuse leaf base shape. South African cultivars vary in leaf blade and leaf apex shape but all of them have acute leaf base shape. Leaf margin and texture vary greatly between cultivars with no dominant shape among any of the three genotypes. The inflorescence length vary significantly (P> 0.5) between genotypes and cultivars with averages of 34.6, 24.2 and 23.3 Cm for the seedling, Grafted and South African cultivars respectively. The color, shape, density and floral leaves of the inflorescence of mango cultivars vary greatly. The color vary between yellow, green, red, green red and dark red with conical or pyramidal shape. Very few cultivars (3grafted and 4 seedling cultivars) exhibited floral leaves. Due to the great diversity between the genotypes and cultivars no specific correlations were found between all of the tested parameters.
