Analysis on Correlation of Yield and Quality under Different Soil Environment in Sugar Beet

The correlation of yield and quality in sugar beet under different soil environment was analyzed. The results showed that the different soil environment has not almost an effect on the correlation between root yield and sugar yield, there were more significant effects on the correlation between root yield and sugar content and ones between sugar content and sugar yield. 87.50% materials exhibited positive correlation between root yield and sugar content in disease field, 31.25% materials exhibited negative correlation between sugar content and sugar yield in non-disease field.
