Selection of genetic materials from segregation population is a main stage in plant breeding, and will help us to get high yield varieties. In this stage proper barley traits that effects crop yield , environmental adaptation and crop quality were selected to increase crop yield potential. Each traits control by one or some genes . Here by with genetic diversity creation and hybridization and different masses of crops can select from segregation population the best varieties resistant to pests and diseases , tolerance to cold and drought , which are important in cold and dry areas. This study carried out in 7 dryland stations: Maragheh, Ghamlo, Ardebil, Ilam, Sararood, Zanjan, Shirvan by cooperation with ICARDA in 2002- 2003 and included 2548 masses in barley segregating population (IWFBSPF3) in 10 experiments. For populations selection from modified bulk method in generation F3 applied. So from 2548 F3 generations 702 populations selected, based on characters: early maturity, drought/ cold tolerance, pests and diseases resistance, lodging and abscission resistance, plant height, proper tiller number, narrow and pubescent leaves, Selected populations will be evaluate in generation F4 in 2003- 2004 .
