Abstract: Acacia mellifera is a widespread species, very common in many area, adaptable to sand and clay soil .and tolerate extreme drought .It has many uses ,it uses as fodder, honey plan, fuel wood., living hedge or fence, edible gum producer and as a medicine for stomach pains and treat colds, eye inflammation, diarrhoea and bleeding. This study was carried to investigate the seed color polymorphism of Acacia mellifera in relation to germination percentage .The result showed that the percentage of the brown greenish seeds almost about half of the bulk, the brown and green almost share the same percentage. The viability of the three colors almost had the same percentage, which means that the color of the seeds was not associated with seed viability further studies were need for demonstrating if this polymorphism associated with seedling performance or with seed storability.
