国家第六轮甘蔗区试品种瑞丽点表现的同异分析

Similarity-difference Analysis of Sugarcane Varieties on Sixth National Sugarcane Regional Trial in Ruili,Yunnan

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 similarity-difference analysis was adopted to make a comprehensive evaluation of the 13 sugarcane varieties of the sixth round of national sugarcane regional trial at Ruili Breeding Station in this paper. The results showed that four varieties, MT95-261 ,FN02-3924, FN99-20169 and YG16, were excellent; six varieties, YG18, MT96-6016, GN99-591, YZ99-91 ,YT93-159 and GY6 （B8）, were good; three varieties, Rb76-5418, ROC16（CKl ） and GF98-296, were ordinary. Except for GY6（ BS）, the comprehensive performances of the other eight varieties are superior to YT93-159 （ CK2 ） which is the local large-scale cultivated variety, so they could be applied to production. ROC16（ CK1 ）, the second large-soale cultivated variety of China, was evaluated as ordinary through this method and had never been used in Ruili. The results of these analyses were identical with the performance in the field, and this review could provide reference for the application of the tested varieties in Ruili and other similar sugarcane growing areas.
