摘　　要：采用同异分析方法对9个引进甘蔗品种进行分析评价。结果表明:P44、C266-70与理想品种联系度分别为0.7676、0.7625,说明其田间综合表现优良,与理想品种最接近,具有较好的推广应用潜力;SP80-0185、VMC71-39、SP80-1836和Q151四个品种与理想品种的联系度在0.70～0.75之间,综合表现一般;Q117、FR97-137、FR98-194三个品种与理想品种的联系度小于0.65,综合表现差。Nine sugarcane varieties were analyzed by similarity-difference analysis.The result showed that both P44 and C266-70 were with good field-performance and strong popularization potential,the connection degree which compared with ideal variety were 0.7676 and 0.7625.The connection degrees of SP80-0185,VMC71-39,SP80-1836 and Q151 were between 0.70 and 0.75,and the comprehensive traits were ordinary.The connection degrees of Q117,FR97-137 and FR98-194 were under 0.65,and the comprehensive traits were bad.The connection degrees of other varieties were between 0.70 and 0.60,and they could tested further.
