Abstract

Three grain sorghum varieties were developed and their performance was accepted named: Sohag-1, Sohag-3 and Sohag-4. They were evaluated with other promising varieties according to graded levels of testing B and C on-station trials at four locations, (Nubaria, Fayoum, Assiut and Shandaweel) in 3 successive seasons starting from season 2018. They significantly out-yielded the check variety (Dorado) D-level. The verification trials (14 trials) were conducted on farmer fields in 4 governorates (Qena, Shandaweel, Assiut and El-Fayoum) where sorghum covered the largest area in 2021 growing season. These three varieties were equal or of higher yield than the check variety and had some other advantages. They were subjected to some studies on their reactions to the sorghum main diseases during 2019 and 2020 seasons where their resistance or tolerance were confirmed to stalk rot and long smut diseases. Their tolerance to some threatening insects, i.e. shoot fly, stem borers and aphid were high to a large extent. In addition to their description, the DNA Finger printing was accomplished and proved that these varieties fulfilled the requirements for registration; they were accepted and registered.
