In Ethiopia, more than 35 improved tef varieties have been realised and disseminated to farmers However, so far the focus of the improvement areas were better yield and good agronomic traits giving little emphasis to quality parameters. This study was, therefore conducted to generate base line information on proximate and mineral composition of released tef varieties and to determine their nutritional quality. All the released tef varieties and local check were grown in Debre ziet research station site under uniform agronomic condition and their proximate composition (moisture, ash, crude protein, fat, fiber, and carbohydrate), energy value and mineral content (Ca, Fe, and Zn) were analyzed and compared. The result showed that different variety had significant effect (p>0.05) on almost all the proximate and mineral contents of the 35 cultivars. However, this study was limited on the grain qualities and single planting season. Therefore, further studies on the grain nutritional and anti-nutritional grain contents; suitability making and development new tef based food products should be studied.
Keywords: Tef cultivars, genotypic difference, grain nutritional quality
