摘　　要：对8个甘蔗新品种(系)的农艺性状进行综合评价,筛选出优良品种(系),为桂西南蔗区特别是龙州蔗区新品种的推广提供参考。以ROC22为对照,对7个甘蔗新品种(系)进行一年新植两年宿根田间比较试验,采用DTOPSIS法对其进行筛选与评价。结果表明,各品种按照DTOPSIS分析结果Ci排序依次为:河糖11-157>桂糖10-1042、桂糖08-56>桂糖11-2320>桂糖09-439>ROC22>桂糖11-2119>桂糖10-417。甘蔗新品种河糖11-157和桂糖10-1042可在桂西南蔗区特别是龙州蔗区进行推广应用,桂糖08-56和桂糖09-439可作为优良新品种继续观察,桂糖11-2320、桂糖11-2119和桂糖10-417不建议在桂西南蔗区推广应用。The agronomic traits of 8 new Saccharum officinarum varieties(lines)were comprehensively evaluated and the excellent varieties(lines)were screened to provide reference for the promotion of new varieties in southwest Guangxi cane area,especially in Longzhou cane area.Seven new Saccharum officinarum varieties(lines)were selected and evaluated by the DTOPSIS method using ROC22 as the control and a comparative field trial of one year new planting and two years persistent root.The results showed that the varieties were ranked in order of Ci according to the results of DTOPSIS analysis:Hetang11-157>Guitang10-1042.Guitang08-56>Guitang11-2320>Guitang09-439>ROC22>Guitang11-2119>Guitang10-417.The new Saccharum officinarum varieties Hetang 11-157 and Guitang10-1042 could be promoted and applied in the cane area of southwest Guangxi,especially in Longzhou,Guitang08-56 and Guitang09-439 could be continued to be observed as excellent new varieties.Guitang11-2320,Guitang11-2119 and Guitang10-417 were not recommended to be promoted and applied in the cane area of southwest Guangxi.
