To study the agronomical and morphological characterstics in 64 safflower genotypes, an expriment was conducted in Dry - land Agricultural Research Station, Sararood, Kermanshah. Quantitative and qualitative traits including flower colour, spine and spineless, days to start and completion of flowering ( DSF , DCF) , days to maturity (DM), plant height (PH), main and lateral head diameter per plant (MHD / P,SHD/P),number of heads per plant (H/P),number of secondary branches per plant (SB), number of seeds per head (S / H), kernal thousand weight (KTW), Seed yield (SY), seed oil content (% Oil), and oil yield (OY) were measured. Analysis of variance showed that safflower genotypes were significantly different for all of the characteristics. Genotypes No. 36 and 37 had the lowest DM. The highest oil yield belonged to genotypes No. 17 , 19 , 33, and 63 ( more of 450 Kg/ha). Mean and variation range were for DM and % Oil 246 and 240 - 256 days, 26.7 and 18.7 - 33.9 %, respectively. Highest phenotypic and genotypic coefficients of variation were obtained for H / P , OY, SB , and SY, respectively. Positive and significant correlations were observed between HD / P and S / H and % Oil. Based on Ward cluster method genotypes were classified into five groups. Genotypes that were superior for % Oil and OY grouped in Cluster No. I and II, respectively. The earliest genotypes were in Cluster No III.
