The main objective of the present study was to; produce a high-yielding populations under variable nitrogen supply through Srjamily selection and determine the correlated responses to selection in yield components and plant characters. In 2004 summer season, an isolatedplots ofabout 0.10 ha was planted with the base population (Alex. 5). Before flowering 300 plants were selected and selfed to produce Sj seeds. At harvest, the heaviest 90 selfed ears were selected and each ear was considered av an Sr line. Depending on the results of evaluation trial, the best 10 percent,
