Two laboratory experiments were conducted in two successive seasons (2014 2015-2015 2016) at the Regional Seed Center Laboratory, Agriculture Research Station (ARC), Elobied. The laboratory treatments were conducted as factorial experiments in a Randomized Complete Block Design (DCBD) with four replications. The estimated quality included seed germination test. The results showed that water regimes had significant effects on germination (%). The highest seedling length was recorded by well-watered plant. The highest seedling growth rate was recorded by plants under well-watered regime. Also the results revealed that genotypes were differing in germination percent, seedling length and seedling growth rate. The results indicated that Taggat genotypes scored the highest values of most seeds quality trials were measured in this study and it might be suitable for high quality and production under rain-fed condition.
