摘要： The flavonoid (Flav) content can be used as evaluation index of plant damage and disease grade. To obtain Flay value of wheat disease leave rapidly and accurately, calibration prediction model of Flay value was established by spectroscopy technology and chemical metrology method. In this study, two algorithm Back Propagation Neural Network (BPNN) and the Least Square Support Vector Machine (LS-SVM) were applicated with the main factor of Partial Least Squares (PLS) as input variable. The results show that the algorithm of LS-SVM is superior to BPNN, and the correlation coefficient and root mean square errors of prediction (RMSEP) of LS-SVM algorithm are 0.9475 and 1.0037 respectively
