Abstract	The extent of variation in seed and germination traits of Sclerocarya birrea subsp. birrea was evaluated at the population level. Seeds were collected from five natural populations in Sudan (Rashad, Alfaid, Alkhwi, Aldamazin and Baw). Five replicates of 25 seeds per population were studied to assess variability in seed morphometric traits, germination index (seed vigor) and total germination percentage, using 100 water-soaked seeds per population sown in a completely randomized block design under controlled environmental condition. Significant (P≤0.05) differences among populations were obtained in seed and germination traits. The analyses revealed that some of the seed traits had significant correlations with the geographical variables of the populations. Among seed traits, significant (P≤0.05) correlations were found between seed length, seed weight and seed width. Germination percentage had no significant correlation with seed traits. With the exception of seed germination percentage, 95%-97% of the total variation in seed traits was attributed to population effect. Variations in seed and germination traits could be a reference point, when considering seed collection of this species for conservation and species restoration.
