Objective:To quantitatively analyze the genetic diversity of tea plant resources,a modeling method of genetic diversity of tea plant resources based on ISSR fingerprint was proposed.Methods:The wavelet multi-scale decomposition method was used to filter the ISSR fingerprint of the genetic diversity of tea plant resources,and the edge contour feature points of the ISSR fingerprint of the genetic diversity of tea plant resources were extracted.The method of regularized feature decomposition is used to enhance the gray-scale information of ISSR fingerprint.The regularization template matching and diversity feature analysis of genetic diversity ISSR fingerprint are carried out by combining block fusion and template matching techniques.The genetic diversity of tea plant resources was modeled by block fusion method.Results:The simulation results show that the information enhancement and recognition ability of genetic diversity modeling of tea plant resources based on this method is better,the extraction accuracy of genetic characteristics of tea plant resources is higher and the recognition ability is better.Conclusion:The ability of quantitative analysis of genetic diversity of tea planting resources was improved.
