摘　　要：利用AMMI模型对17个甘蔗品种的蔗茎产量(CY)、蔗糖分(SC)和含糖量(SY)进行稳定性分析,并以这3个性状的表型值和相应的品种稳定性参数(Dg)为指标,对供试品种进行系统聚类分析和评价。结果表明:甘蔗CY,SC和SY在不同品种和环境的差异以及品种与环境互作效应都达到显著水平(P<0.05);综合考虑CY,SC和SY的表现和稳定性,福农91-4710、闽糖86-2121为高产稳定性较高的品种,粤糖93-159和云蔗92-19为高糖稳定性较好的品种,粤蔗C25和桂糖92-262为低产稳定性最好的品种。The stability of 17 varieties on cane yield （CY）, sucrose content （SC） and sucrose yield （SY） of sugarcane were analyzed by using additive main effects and multiplicative （AMMI） model. Seventeen varieties under test were further clustered and evaluated on the phenotypic values of three characteristics and their Dg value from the AMMI analysis. The results showed that the differences of CY, SC and SY between genotypes and environments and of correlation effect between genotype and environment were all significant at 5 % level. When CY, SC and SY, and their stability in varieties were considered, varieties FN91-4710 and MT86-2121 had higher yield with higher stability, and varieties YT93-159 and YZ92-19 had higher sucrose content with higher stability, whereas YZC25 and GT92-262 had a lower yield with the highest stability.
