Abstract: In order to make a more comprehensive evaluation of fruit quality and select better fruit varieties more reasonably.In this study, ‘Laiyangchili’of 16 orchards were used as the test materials, and the distance closeness degree and grey relational closeness degree were determined by MATLAB software.Based on the idea of game theory, the combination coefficient of closeness degree was calculated, and then the comprehensive closeness degree was obtained, and the GC-ITOPSIS fruit evaluation model was constructed.The results showed that the comprehensive pasting progress of sample 1 was the largest,and the fruit quality was the best,the fruit quality of‘Laiyangchili’in the first orchard was the best.On this basis,this study realized the quantitative prediction of fruit quality,established the BP prediction model of fruit quality,and the prediction accuracy was less than 7%.The combination of GC-ITOPSIS model and BP prediction model not only realizes the quantitative prediction of fruit quality,but also improves the convenience and accuracy of fruit quality evaluation.
