广西甘蔗新品种区试柳州点7个甘蔗新品种DTOPSIS法综合评价

【目的】对7个甘蔗新品种（系）的田间表现进行综合评价，筛选优良品种，为其在柳州蔗区的推广应用提供参考依据。【方法】在柳州蔗区条件下，对参与广西甘蔗新品种区试的7个甘蔗新品种进行田间一年新植和一年宿根品比试验，并采用DTOPSIS法对其表现进行综合评价。【结果】在7个参试品种中，以桂辐98／296的宿根萌苗率、分蘖率、有效茎数、蔗茎产量、蔗糖分和产糖量表现最好，其他品种表现无明显规律。桂辐98／296、桂糖04／120、玉林1号的综合性状优于对照新台糖22号，而柳城03／362、桂糖04／2278和桂糖02／496低于对照新台糖22号。7个甘蔗品种的c值从高到低排序为桂辐98／296、桂糖04／...

Summary:【目的】对7个甘蔗新品种（系）的田间表现进行综合评价，筛选优良品种，为其在柳州蔗区的推广应用提供参考依据。【方法】在柳州蔗区条件下，对参与广西甘蔗新品种区试的7个甘蔗新品种进行田间一年新植和一年宿根品比试验，并采用DTOPSIS法对其表现进行综合评价。【结果】在7个参试品种中，以桂辐98／296的宿根萌苗率、分蘖率、有效茎数、蔗茎产量、蔗糖分和产糖量表现最好，其他品种表现无明显规律。桂辐98／296、桂糖04／120、玉林1号的综合性状优于对照新台糖22号，而柳城03／362、桂糖04／2278和桂糖02／496低于对照新台糖22号。7个甘蔗品种的c值从高到低排序为桂辐98／296、桂糖04／120、玉林1号、桂糖04／2278、新台糖22号、柳城03／362、桂糖02／496。【结论】桂辐98／296、桂糖04／120、玉林1号适宜在广西柳州地区及气候相似蔗区大面积推广应用，而桂糖04／2278、柳城03／362、桂糖02／496则不宜在该类型蔗区推广应用。

Objective]The 7 new sugarcane varieties （lines） performance in field were comprehensively evaluated to select fine varieties in order to provide references on their extension and application in Liuzhou sugarcane planting areas. [ Method ] Under condition of Liuzhou sugarcane planting areas, 7 sugarcane varieties in Guangxi regional trial of new su- garcane varieties was used to conduct one-year-newly planting and one-year-ratoon comparative test. Their performances were comprehensively evaluated by using DTOPSIS method. [ResultlAmong 7 tested sugarcane varieties, the budding rate of ratoon cane, tillering rate, effective stalks, cane yield, sucrose content and sugar yield of Guifu 98/296 showed better in general, but the other 6 varieties presented no apparent rules. The comprehensive traits performance of Guifu 98/296, Guitang 04/120 and Yulin l was better than that of ROC22 （CK）, while Liucheng 03/362, G
