摘要：

Plant tissue sap analysis is becoming an established tool for crop fertilization recommendation. Few research was conducted to use it as screening tools in crop breeding. With introduction of hhand-held sap analysis meters, sap analysis is becoming a promising tool for genotype screening. In this study, we measured Brix and pH of flag leaf juice of 10 winter wheat genotypes after heading stage. Brix value tended to increase during the measurement period. Brix value of flag leaf sap was negatively correlated with kernel number per spike and grain yield per spike, positively correlated with kernel weight. The pH values of flag leaf sap were negatively correlated with kernel number per spike and grain yield per spike, positively correlated with kernel weight.
