Production of new cultivar with alternative genetically traits, need to genetic diversity that breeder can produce favorite heredity structure with desired environmental conditions. In this research, 128 segregation populations including 61 number of F2 generation, 45 number of F3 generation, 19 number of F5 generation and 5 number of F7 generation participated that were evaluated using modified bulk in Gachsaran agricultural research station in 2008-2009. Evaluation of population based on desired physiological and agronomical characteristics for semi-warm dryland conditions such as plant growth vigor, growth type, favorite phenotype such as height, stem and leaf angle, synchronization of spikes, earliness, tolerance to heat and drought stresses and resistance to common diseases. In basis of, selected populations of each generation will test in research advanced stages in next year.
