In Conventional Plant breeding, hybridization is the most effective method for producing new desirable cultivars. Segregating within populations starts from F2 generation and continues to F6 or F7. To obtain stable genotypes of durum wheat for harsh environments and adaptable to drought, heat and other stresses of CWANA region ,1450 F2 populations and F3 generation derived from ICARDA crossing block program were planted and studied in Dezful research station . Modified bulk method was used for selection of the plants with desirable characteristics such as suitable height , earliness, size and type of spikes , tolerance or resistance to the common diseases , strong and synchronized tillers , lodging resistance , durability of the leaves , and finally 207 generations were selected for next crop season(table 1).
