  Generating pyramid lines via multiple crosses is one of the most important strategies for rice breeding. 126 F3 lines generated from Ghaem as a female line and Shastak, Fajr, Domsiyah and Nemat as male lines including Neda and Sangetarom as check varieties studied in the form of augmented design at the experimental field of GABIT. Variance analysis indicated significant differences of agromorphological traits between check and others lines. Cluster analysis of check varieties based on ward method was conducted and Pearson correlation coefficient indicated possitive and significant correlation (P=0.1) between fertile tillers (r=0.91) and 1000 grain weight (r=0.97) with yield. Although 28 lines indicated significant differences with Ghaem check variety but only GF//GD-03-3 and GD//GS-03-1-23 lines have shown higher yield regarding to high yield Neda check variety. Three GD//GS-03-1-23, GD//GS-03-1-25 and GF//GN-03-2-18 lines have had excellent ideotype and seven clusters obtained from cluster analysis in which superior lines belonged to cluster 4 and 5.
