Response of 8 bread wheat recombinant inbred lines along with their parental cultivars (Roshan and Super Head) to water deficit was evaluatedin a split plot experimentarranged in randomized complete block design (CRBD) with three replications under three irrigation levels (80, 120 and 160 mm evaporation from the pan) at the Agricultural Research Station of Islamic Azad University, Tabriz Branch in 2009. Univariate analysis of variance revealed significant difference among lines with respect to all the traits studied. Significant differences were observed among irrigation levels for grain yield and thousand-grain weight. Line × stress interaction was significant for harvest index and number of fertile and non-fertile tillers. Roshan cultivar produced highest grain yield. In the factor analysis, the first three factors explained 86.95% of total variation. The two first factors were named as growth and grain yield factors, respectively. Cluster analysis, using WARD algorithm, based on all the traits grouped the lines into two cultivars. Grouping was confirmed by discriminate analysis.
