Abstract
The study aimed to determine the grain quality of twenty genotypes of bread wheat grown in Northeastern Libya. Nineteen newly introduced genotypes from ACSAD (Arab Center for the Studies of Arid Zones and Dry Lands) were compared with an improved local, high-yielding potential variety. The experimentation was conducted in the growing season 2020-2021 under rain-fed conditions. The results showed a significant difference amongst the tested genotypes in test weight, thousand kernel weight, falling number, hardness, moisture, protein content, wet gluten, gluten index and Zeleny sedimentation volume. The study indicates that the two introduced genotypes, ACSAD 1476 and ACSAD 1492, among all tested genotypes, demonstrated their ability to adapt to the conditions of the region by possessing the acceptable qualitative characteristics necessary for bread making, compared to the local variety BUHOUTH 210.
