Making genetic diversity by hybridization and selection in segregation populations is usual for self in plants breeding. Breeders use of variation derived from hybridization to catch new varieties of cereal. Some of this progenies can show superior ability to produce yield and adaptability than checks. In this assessment 453 segregation lines in two trial (F5, F6; 262 and 191lines respectively) was evaluated. Desirable trait such as plant height, maturity, disease resistance, and was recorded for each line and used for selections.
