Abstract Leaf chlorophyll content (LCC) is a key indicator for assessing the growth of grapes. Hyperspectral techniques have been applied to LCC research. However, quantitative prediction grape using this technique remains challenging due baseline drift, spectral peak overlap, and ambiguity in sensitive range. To address these issues, two typical crop leaf hyperspectral data were collected reveal response characteristics standardization by variables (SNV) multiple far scattering correction (MSC) preprocessing variations. The range determined Pearson’s algorithm, features are further extracted within that Extreme Gradient Boosting (XGBoost), Recursive Feature Elimination (RFE), Principal components analysis (PCA). Comparison ability Random Forest Regression (RFR) Support Vector Machine (SVR) model, Genetic Algorithm-Based Neural Network (GA-BP) on based features. A SNV-RFE-GA-BP framework predicting grapes proposed, where $$\:{R}^{2}$$ =0.835 NRMSE = 0.091. results show SNV MSC treatments improve correlation between reflectance LCC, different feature screening methods greater impact model accuracy. It was shown SNV-based processed combined with GA-BP has great potential efficient monitoring grapevine. This method provides new theory constructing analytical grapevine indicators.
