Wheat is one of the most important and widely- cultivated crops in the world. The global consumption of wheat, which is close third after rice and maize, continuously increased during the past decades and is expected to increase to 600 million tons in 200-2004.Segregating populations due to their high genetic diversity, play an important role in plant breeding. In this investigation 19, 50 and 11 population respectively in F3, F4 and F5 generation, for study in next generation were selected. Also 135 populations were selected from F6 generation. Five spikes from each F6 generation were selected and would be planted as head to row in next season. Selection was based on visual agronomic characters in field condition. From each selected generation 20 heads from different lines in each population were selected to create the next generation populations.
