Evaluating the Seed and Oil Yield of Exotic and Iranian Safflower Genotypes

To determinate eight exotic adaptable safflower genotypes for seed and oil yields (Hartman، Kino 76، Sonora 92، Bacum 92، Saff – 891، Mantel 81، CW 88، Sidwiil) and two Iranian ones (Goldasht، S-55) selected from Ajabshir mass، an experiment was conducted in Bojnord by RCDB design in 2010-2011. During growth period important traits such as germination time، stem elongation time، days to heading، days to flowering، days to 50% flowering، days to maturity، head number per plant، number of seeds per head، were recorded. The experiment was irrigated after planting، beginning of stem elongation، beginning of flowers appearance، beginning and after flowering، seed filling stage. Analysis of variance was conducted on seed yield، oil percent and yield components. Comparison of means was done after significance of F- test. Results showed Goldasht with 1056 kg/ha seed yield and 304 kg/ha oil yield highest rank. Correlation of seed yield and oil yield، seed yield and head number، number of branches and plant height showed significant correlation between them. Cluster analysis showed that Iranian and exotic genotype were separate together.
