摘要
The weights of ten important traits of sugarcane, including the number of hair groups, plant height, defoliation capability, stalk diameter, ratooning property, stalk number of disease resistance, cane yield, sucrose content and sugar yield, were distributed with the Analytic Hierarchy Process （AHP） method. Ten Yuetang series of sugarcane lines were evaluated by Dynamic Technique for Order Preference by Similarity to Ideal Solution （DTOPSIS）. AHP results indicated that the weights of ten traits were 0. 013 4, 0.022 7, O. 030 2, 0.040 8, 0.065 3, 0.088 1, 0.116 2, 0. 160 6, 0.198 4 and 0.264 5, respectively, with random consistency ratio C.R. =0.098 1 〈0.1, suggesting that the distribution of the weights of evaluation indicators was reasonable. Comprehensive evaluation of 10 sugarcane lines by DTOPSLS method combining with the conclusion of AHP showed that the comprehensive performances of Yuetang 03-393 and Yuetang 03-373 were much better than other sugarcane lines, with relative approach degree Ci ranking the first and second, respectively, which was basically consistent with the practical survey, suggesting that Yuetang 03-393 and Yuetang 03-373 were suitable for large-scale popularization. The above results confirmed the feasibility of applying AHP and DTOPSIS in comprehensive evaluation of new crop varieties and provided reference for the breeding of new sugarcane lines.
