Abstract: 【Objective】The good germplasm was screened out by comprehensive evaluation of various characters of Sterculia nobilis Smith, which provided reference for accelerating the breeding of new varieties.【Method】The mathematical model of analytic hierarchy process(AHP) -fuzzy comprehensive evaluation(FCE) was applied to establish and evaluate the comprehensive evaluation system of 20 S. nobilis Smith materials, then, dynamic technique for order preference by similarity to ideal solution(DTOPSIS) was used to select the lines with good comprehensive traits.【Result】The weights of 4 criterion indexes and 11 single indexes constructed by AHP method passed the consistency test. After FCE analysis, the final score of the comprehensive evaluation system of S. nobilis Smith was 90.02, and the evaluation result was excellent.The relative proximity values(C_i) of each ideal solution of 20 lines were greatly different by using DTOPSIS method, the Civalues of lines NYS-17 and NYS-12 were 0.77852 and 0.77843, respectively. It presented that the tree was tall, the average yield per plant was high, the edible rate was high, the resistance was strong, and the content of starch, soluble sugar and soluble protein was high, and the comprehensive performance of NYS-7, NYS-8, NYS-10, NYS-11 and NYS-9 was bad, which were consistent with the actual observation results in the field.【Conclusion】In this study, AHP-FCE mathematical model and DTOPSIS method are used to comprehensively evaluate the germplasm resources of S. nobilis Smith, the excellent lines NYS-17 and NYS-12 are screened out.
