Wheat is one of the most important cereal crop world-wide that grown in many areas and major staple crops in Ethiopia but its production at lowland areas are very limited because of this lowland areas in Ethiopia are characterized by higher temperature and low rainfall condition, mostly are not suitable for crop production. In addition to this bread wheatis very susceptible to high temperature stress condition and their adaptability and also lack of variability of genotypes in lowland stress environment is a key factor. Therefore mostly wheat production in the country is in mid to highlandareas, so that the practice of wheat production in lowland stress area is scarceor not available.Thus, information on the extent and performance of genotypes present in a crop species under high temperature stress are essential for effective crop adaptation program. To generate these information 36 bread wheat genotypes with three released varieties (Fentalle, Amibara and Werer-2) were tested at the Werer agricultural research center, Afar in 2017 in Triple Lattice Design with three replication.
