Most sources report from durum wheat as a resistant to drought wheat. Durum wheat hasn ,t been important in Iran, despite water deficit and drought long periods in large sections of lands under wheat cultivation and confirmed requirement maccarony production industries to durum wheat semolina. Traits segregating are started from F2 generation in segregating of population and continue until generaton several. In these stages, various combinations are appeared between fatherhood and motherhood traits, and with studyind and controling plants and populations in different growth stages, the plants are selected that have desirable agronomical characteristics, tolerant or resistant to drought and diseases and other incompatibility of planted environment and full of productivity. This study contains 80 entries of durum wheat international F4 generation. The samples were planted in 6 rows of 6.65 meters with cereal planter and after cutting 52.5 cm from first and end of plot remained 6 Square meter. Selectin methode was pedigree in this stage, scince plants are near to genetical purity, therefore from per mass is selected 1-3 plants and maximum 5 plants, separatly is harvested and threshed. The selected seeds of plants are counted after controling. The results showed that from 80 masses durun wheat international F4 generation were selected 34 masses(79 entries) for studying in F5 generation untill receiving to genetical purity.
