The new durum wheat cultivar Bani Sweef 4 has been selected from one of the advanced lines among exotic collections grown in wheat breeding program at Sids Research Station. The grain yield of the new cultivar Bani Sweef 4 was evaluated thought 44 experiments conducted three different levels (5 micro, 18 macro and 21 verification yield trials) from 2001/2002 to 2005/2006 seasons. The obtained results proved the superiority of the new cultivar Bani Sweef 4 compared with the local commercial checks; Bani Sweef 1 , Bani Sweef 3 and Sohag 3 in Middle Egypt and in some other parts in Upper Egypt in yield ,physical and chemical content. Moreover, the new cultivar Bani Sweef 4, expressed its high resistance to the three wheat rusts (stripe , leaf and stem) at both seedling and adult stages . In addition, Bani Sweef 4 showed high semolina percentage content comparing to the other three local checks (Bani Sweef 1 , Bani Sweef 3 and Sohag 3 ) . It could be concluded that Bani Sweef 4 is recommended for Middle Egypt for high grain production and grain quality per unit area .
