A new semidwarf cultivar “Uruq” developed from irradiated stored seeds of soft wheat cv. “Inia-66”

A new semidwarf cultivar Uruq was developed by irradiated storage seeds of Inia-66 cultivar. Cultivar Uruq has many quantitative and qualitative characters which surpassed its parent (Inia-66), first of all, by reduction of height by 25 cm, which leads to lodging resistant character and, the locally desirable amber seeds color instead of red seeds color which characterize the seeds of parent plant (Inia-66).Uruq cultivar also surpassed its origin in yield components at different environmental conditions, resistant to brown leaf rust, and suitable for bread making according to their physical and chemical characters and baking test.The techniques at the molecular level showed that Uruq cultivar has the dwarf gene Rht-D1b which is responsible for the semidwarfism
