The Study of Biological Yield, Grain Yield and Oil Yield in Spring Safflower Varieties Under of Condition Water Streets

摘要

Safflower is one of humanity’s oldest crops,for determination of drought tolerance of spring safflowercultivars and studying yield and yield components in control and stress conditions, an experiment wasconducted. Irrigation in two levels (control and drought at rosette ending period) in main plots and 12 cultivarsas (Syrian, PI-537598, Gila, Lesaf, Dinger, 697, Cw- 4440, PI-250536, Hartman, Kino-76, LRV-51-51, S541)as subplots arranged in a RCBD base split plot in three replicates. In plots that were under water stress (stressfrom the end stages of forming stem growth) do not have any irrigation. Results of analysis of variance showedthat the genotype effect of simple traits, oil yield is significant (P<0.05). Highest grain yield in irrigatedconditions to variety of S541(3845 kgha) and in Conditions without irrigation have variety of PI 250536(463.7kgha). That are recommended for agriculture in the region for the experiment.
