国家第八轮区试甘蔗新品系在云南瑞丽点表现的DTOPSIS法评价

[目的]综合评价国家甘蔗品种区试参试品系,筛选优良品系,为其在生产上的应用和推广提供参考.[方法]在云南瑞丽蔗区的湿润气候生态条件下,采用DTOPSIS法对国家第八轮甘蔗品种区试参试品系进行综合评价,筛选具有推广潜力的甘蔗品系.[结果]在10个参试甘蔗品系中,柳城03-1137、云蔗05-51、福农39和云蔗06-407等4个甘蔗品系的综合表现皆优于两个对照品种ROC22和ROC16,赣南02-70、粤甘35的综合表现介于两个对照之间.DTOPSIS法分析结果表明,不同甘蔗品系C值大小排序依次是柳城03-1137、云蔗05-51、云蔗06-407、福农39、ROC22（CKl）、粤甘35、赣南02-70、ROC16（CK2）、云蔗04-241、福农02-5707、福农36、粤甘34.[结论]柳城03-1137、云蔗05-51、福农39和云蔗06-407等4个品系适于在云南瑞丽湿润气候生态型及其气候相似蔗区优先推广应用;赣南02-70表现早熟、中产,亦可在该类型蔗区应用,但在栽培过程中要注意防倒伏.

DTOPSIS evaluation of the eighth national sugarcane regional trail in Ruili Site of Yunnan

[ Objective ]The sugarcane lines trial in national regional were comprehensively evaluated for better variety selection to provide references for its application in production and extension. [Method ]In the humid climate ecological conditions of Ruili in Yunnan sugarcane area, DTOPSIS method was used for the comprehensive evaluation of all sugar- cane lines in 8~-time national sugarcane regional trail to screen out promising sugarcane varieties. [ Result ] Among ten tested sugarcane varieties, the comprehensive performance of Liucheng 03-1137, Yunzhe 05-51, Funong 39, and Yun- zhe 06-407 was superior than that of the two controls （ROC22 and ROC16）. The comprehensive performance of Gannan 02-70 and Yuegan 35 was between the two controls. DTOPSIS analysis results showed that Ci sequence was Liucheng 03- 1137, Yunzhe 05-51, Yunzhe 06-407, Funong 39, ROC22（CKI）, Yuegan 35, Gannan 02-70, ROC16（CK2）, Yunzhe 04-241, Funong 02-5707, Funong 36, Yuegan 34. [Conclusion]Liucheng 03-1137, Yunzhe 05-51, Funong 39 and Yunzhe 06-407 were suitable for Ruili and similar sugareane areas of Yunnan where exhibited humid elimate eeologieal eonditions. Gannan 02-70 matured early with moderate yield, henee it also could be applied in this kind of sugarcane area, but lodging should be prevented during the eultivation.
