Abstract: To screen the sunflower varieties with salt tolerance, 14 sunflower material as the experimental mate-rial,starting from the effects of salt stress on sunflower agronomic traits, yield traits and physiological and biochemi-cal response, and through gray correlation analysis and path analysis, discusses under salt stress of sunflower yield formation factors.The main results are as follows:0.26%stress associated with yield of agronomic traits is the num-ber of blades.In 0.39%under salt stress related to yield traits of maximum height.In 0.83%under salt stress re-lated to yield the greatest degree of agronomic traits of leaf area.Under salt stress is relatively light yield and maxi-mum yield correlation is 100 grain.Under severe stress and maximum yield correlation of yield is a single disc grain weight.Under different concentration of salt, the response in the growth index of the sunflowers differences.Differ-ences related to yield traits on stress of different concentrations of salt is also great.The same index in different salt stress,positive and negative effects on yield are also different.
