The Investigation of some phenological and agronomical traits in spring safflower (Carthamus tinctorius L.) genotypes in Karaj region

In order to determine physiological differentiations of the spring safflower genotypes, a trial was conducted in Karaj Research Institute for Seed and Plant improvement in 2003. In this experiment 7 safflower varieties and lines were compared in a randomized complete Block Design with four replications. Some important traits such as: biomass, harvest index, day to booting, day to flowering, day to 50% of flowering and day to maturity were recorded during the growth period. Statistical analysis (ANOVA)shown minimum of day to 50% of flowering, day to end of flowering and day to maturity 68,83 and 102 days related to I.L.111 respectively. The maximum of biomass related to I.L.111 to 59.8 g/plant and high rate of harvest index to 28.5% related to I.L.I 11. As a conclusion the new and advanced line (I.L.1 11) can be introduced for Karaj and similar regions, as suitable and new spring safflower variety.
