In order to study of agronomic characteristics, yield and yield components of different safflower genotypes, a field study was conducted at research field of Karaj Seed and Plant Improvement Institute, using randomized complete block design with four replications during 2003-2004 growing season. Seven genotypes were compared.Number of seed per head, number of head per plant, 1000 seed weight, seed yield, biological yield, oil yield, seed oil percentage, number of axillary branches and harvest index were investigated. Results indicated that for increasing seed oil, at first, must increase seed yield. This character depends on biological yield and number of head per plant.Seed yield was significantly and positively correlated with the following traits: oil yield, number of head per plant, 1000 seed weight, number of axillary branches, biological yield and harvest index; on the other hand, there existed negative significant correlation between number of head per plant and seed oil percentage, oil yield and number of seed per head. Also, 1000 seed weight was negatively correlated with number of seed per head. For selection of a genotype, traits such as high yield, high oil, early maturing, great height are main indices; thus in present study, L.R.V.51.51 genotype including above mentioned characteristics is suitable and adaptive for planting in Karaj region.
