“…The Wheat Research Department released many highyielding durum wheat cultivars of high quality, which had a big role in the increase of production. These durum wheat cultivars started with the cultivar Sohag 1 (Gomaa et al, 1979), and then followed by a series of durum wheat cultivars, Bani Suef 1 and Sohag 2 (Abdel-Shafi et al, 1989), Sohag 3, which out yielded Sohag 1 by an average of 10% (Ghanem et al, 1991), Bani Suef 3 (Ghanem et al, 1996), Bani Suef 4, which proved its superiority in grain yield compared with the other commercial cultivars (Abdel-Aleem et al, 2008), Bani Suef 5 of the high yielding ability (Moustafa et al, 2008) and Bani Suef 6, which has better stability parameters in ' Middle and Upper Egypt (Sadek et al, 2011) -and recently Sohag 4 (Hamada et al, 2015), Sohag 5 (Hamada et al,2016) and Bani Suef 7 for Middle and Upper Egypt (Abd El-Majeed et al, 2017).…”
