Abstract
Due to the growing demand for edible oils, oilseed crop development is very important. Safflower (Carthamus tinctorius L) is a native of Iran oil seed. This crop is compatible with the environmental conditions in the country as well; this is especially true in areas exposed to non-biological stresses such as drought and salinity, but there are no enough studies about this plant. In order to investigate the effects of drought stress on the grain yield, an experiment was conducted split plot and completely accidental blocks plan with two replicates in normal conditions (7irrigation) and two times drought stress ( 6 and 5 irrigation, respectively) by 26 varieties. In this research, we measured and studied the traits like the day number to germination, the day number to stalk appearance, the day number to 50% budding, the day number to 50% flowering, the day number to 100% flowering, the bush height, the number of the boll per bush, the number of the grain per boll, 1000-grain weight, the plant performance and the oil content. The results of the variance analysis showed that there are significant differences between the different irrigation levels regarding the traits, only the 1000 grain weight with 5% possibility and the boll number per bush with 10% possibility. A significant difference was seen between studied varieties regarding the investigated traits which show the genetic diversity of the varieties. According to the results from the comparison of the varieties mean, the least 1000 grain weight belonged to Zaragan2 local variety and the most one was about the foreign variety, Nebraska. According the results of the compression of the varieties mean in the irrigation levels, the plant performance and 1000 grain weight increased with the irrigation time’s growth in the production stage. In this research, the varieties with more 1000 grain weight had high plant performance. The plant performance of the safflower different varieties in this experiment were variable in the slope of 13/5 – 20/75g and the most plant performance mean belonged to N51016 and the least one was related to Zaragan4 local. The oil content of varieties had changes from 35/37& in TOMJIK to 25/06% in Kordestan2 local. The genetic diversity between the safflower different varieties is the main factor of oil content changes. The interaction effects of varieties in irrigation levels were not significant for any of the investigated traits, in other words, the varieties and irrigation levels were acted independently on the traits.
