In attention of existence of different characters in barley cultivars which any were effected yield rate and adaptability to agronomic conditions and production quality and finally, was controlled by the number of geneshowever, make of genetically diversity and different hybrids productionwas probable the selection of lines that adaptation with agroclimatical conditions. Selection in segregation materials is the most important stages of breeding programs and help us to obtain the high-yielding and adaptive to regional conditions .Characters segregation in hybrids were initiated from F2 population and continued for several generations. In this stage, diverse compounds between of parental materials were displayed. The surveying of single plants in various stages of plant growth desirable plants which possessed high yield characteristics was selected. In this experiment 26 F2 population, 74 F3&F4 (15 F3& 59F4),& 142 single plant from F5-Fn studied& 177,23,15,and 149 numbers in F2 , F3 , F4 , (F5 and Fn) generation were participated, respectively that , 147 number from F2 generation, 23 numbers from F3 generation , 15 suitable single- plant from F4 population, 108 suitable single-plant pure lines from F5 and 31 ,F6 and 10 F7, generation were selected to additional survey in future year. And have sent to cereal section .
