In this study, barley hybrid populations and segregating generations including:(133 F2 's, 178 F3 's, 275 F4's, 115 F5's) and 45 F6- Fn families, using Modified Bulk Method were evaluated. In totally, 130 F2's, 157 F3's, 309 plants of F4, 106 lines of F5 and F6- Fn generation were selected, to participate in next generations and Preliminary Barley Screening Nurseries experiments(PBSN) in next year. Some significant traits, such as: resistance to diseases and lodging, non-shattering, tillering, plant height and type, early maturity and seed health were selection criteria.
