Investigation of Yield and Earliness Traits in Safflower Mutants in Irrigated and Drought Stress Condition

The safflower or Carthamus tinctorius belongs to Astcraceac family. As a forage and oil crop. It is commonly used in dry or non dry farms. In this research, the seeds of Zarghan 279 as a winter variety was radiated by Gamma ray in 80, JOO, 150 and 200 Grey doses and they were sown in farm. The mutants after the second generation, were under dry stress and non stress conditions and they were grown and selected up to the 5 th generation. Me. Their traits were measured in the final generation of mutants, The results shows that in two conditions yield, days to buding. days to start of flowering, days to 50~/o flowering, days to maturity and difference of days to maturity and days to buding were significant between mutants at I% level. The difference in the oil percentage In two conditions were not significant
