采用同异分析法对参加国家第六轮甘蔗区域试验的13个品系在云南瑞丽点的表现进行综合评价,结果表明,同异分析评价为优秀的是闽糖95/261、福农02/3924、福农99/20169和粤甘16号4个品系,良好的是粤甘18号、闽糖96-6016、赣南99-591、云蔗99-91、粤糖93-159(CK2)和桂引6号(B8)6个品系,表现一般的是Rb76-5418、桂辐98-296和ROC16(CK1)3个品系。在同异分析评判优良的10个品系中,除桂引6号(B8)外,其余8个品系的综合表现均优于当地大面积栽培品种粤糖93-159(CK2),可在生产上示范应用;在全国种植面积排第二位的ROC16(CK1)号,在瑞丽试验点同异分析评价表现一般,其在云南瑞丽蔗区生产上基本没有应用。试验结果与品系材料在田间的实际表现吻合,可作为参试品种在云南瑞丽湿润气候生态区及其相似蔗区推广应用的参考依据。
The sameness and difference analysis was used to evaluate the performance of 13 lines participating in the sixth round of sugarcane regional trials in Ruili, Yunnan Province. The results showed that the same-differences analysis and evaluation were excellent for Fujian sugar 95/261, FuNong 02/3924 , Four strains of Fuinong 99/20169 and Yuegan 16, and the good ones are Yuegan 18, Minban 96-6016, Gannan 99-591, Yunxian 99-91, and Yueshun 93-159 (CK2) and Gui Yin 6 (B8) 6 lines, the performance of the general Rb76-5418, Gui Fu 98-296 and ROC16 (CK1) 3 lines. Among the ten lines with the same-different analysis and evaluation, the comprehensive performance of the remaining eight lines was superior to that of the large-area local cultivar Yue-Guang 93-159 (CK2) except Gui-Gui 6 (B8) Demonstration application; ROC16 (CK1) ranked the second place of planted area in the country has the same performance in the analysis and evaluation of the same site in Ruili, but it has no application in the production of sugarcane area in Ruili, Yunnan Province. The experimental results are consistent with the actual performance of line materials in the field and can be used as a reference basis for the popularization and application of the tested varieties in the humid climate and ecological zone of Ruili, Yunnan.
