摘　　要：文章采用DTOPSIS法和灰色关联度法对第八轮国家甘蔗区试开远试点品种进行了综合评价。结果表明,2种方法综合评价结果基本相同,且与甘蔗品种在云南开远蔗区的实际表现相符,其中云蔗06-407表现最优,其次是柳城03-1137、赣南02-70。研究认为,DTOPSIS法中Ci值的最大差异达到163.3%,灰色关联度法中加权关联系数ri的最大差异仅有10.3%;DTOPSIS法比灰色关联度法在客观评价品种方面更加准确。By DTOPSIS and gray related degree,the new varieties from the eighth national sugarcane regional trial in Kaiyuan of Yunnan were evaluated. The result showed that comprehensive evaluation results of two methods were basically the same and consistent with actual performance of sugarcane varieties in Yunnan Kaiyuan. Among these varieties,Yunzhe06-407 was the best,followed by Liucheng03-1137 and Gannan02-70. The result indicated that DTOPSIS or gray related degree could completely and objectively evaluate varieties. The biggest difference of Civalue in DTOPSIS method was 163. 3 %,but the biggest difference of the weighting correlation number（ ri） in grey related degree had only 10. 3 %. DTOPSIS was better than grey related degree.
