Twenty four crosses were developed from eight cyto- plasmic male sterile lines (CMS- Lines) and three restorer lines (R- Lines) at Shandaweel Agric. Res. Station, Sohag, Egypt, in 2009 season. Three experiments were conducted separately for each N level (the first experiment with 80 Kg N/Fed., the second ex- periment with 100 Kg N/Fed. and the third experiment with 120 Kg N/Fed.,). The twenty four crosses and their parental lines with the check (Shandaweel-6) were evaluated under the three levels of nitrogen in two locations at Shandaweel Agric. Res. Station, Sohag and at Arab El-Awammer Agric. Res. Station, Assiut in 2010 season. Data were recorded on days to 50% flowering, plant height (cm.), 1000- grain weight (g.) and grain yield / plant (g.) were developed from eight cyto- plasmic male sterile lines (CMS- Lines) and three restorer lines (R- Lines) at Shandaweel Agric.
