【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 i值大小排序依次是柳城03-1137、云蔗05-51、云蔗06-407、福农39、ROC22(CK1)、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。
【Objective】 The purpose of this research is to evaluate the national strains of sugarcane varieties in the district test and screen the fine lines for their application and popularization in production. 【Method】 Under the condition of wet climate in Ruili sugarcane field of Yunnan, DTOPSIS method was applied to evaluate the regional trial of the eighth round of sugarcane varieties in China. The sugarcane lines with potential for popularization were selected. 【Result】 Among 10 tested sugarcane lines, the comprehensive performance of 4 sugarcane lines, Liucheng 03-1137, Yunxian 05-51, FuNong 39 and Yunzhu 06-407, were superior to those of the two control cultivars ROC22 and ROC16 , Gannan 02-70, Yue Gan 35 comprehensive performance between the two controls. DTOPSIS analysis showed that the order of C i values of different sugarcane lines was: Liucheng 03-1137, Yunxian 05-51, Yunzhan 06-407, Fuinong 39, ROC22 (CK1), Yuegan 35, Gannan 02- 70, ROC16 (CK2), Yunxian 04-241, Fuonan 02-5707, Funong 36 and Yuegan 34. 【Conclusion】 Four lines Lianyungang 03-1137, Yunxian 05-51, Funong 39 and Yunxian 06-407 are suitable for preferential popularization and application in the wet climate and the climate-like sugarcane fields in Ruili of Yunnan Province. Gannan 02- 70 performance of early, middle class, but also in this type of sugarcane area application, but in the cultivation process should pay attention to lodging.
