中文摘要：应用作物品种区域试验非平衡资料的分析方法,对参试的5个甘蔗品种的9个主要性状4年6个试点的非平衡资料进行分析,结果表明:(1)环境因素对不同性状的效应不同,蔗茎产量以年份和试点的效应为主,蔗糖产量是年份及基因×年份互作效应为主;(2)7个主要性状与蔗茎产量之间及其与蔗糖产量之间的协方差分量效应基本一致;(3)甘蔗品种粤糖93/159和Roc22的9个性状表现均较优良,综合性状和蔗茎产量及蔗糖产量的稳定性较好,是生产上可大面积推广应用的优良品种.

外文摘要：Unbalanced data from 9 major traits of 5 sugarcane varieties on 6 locations in four years were analyzed. The results indicated: (1) The effects of environment on different traits were not the same, such as the stalk yield were mainly affected by years and locations, while the sugar yield were mainly affected by years and genetype×years interaction. (2) The covariances effects among 7 major traits and sugar yield were basically the same. (3) Nine major traits in Yuetang 93/159 and Roc22 were better, and the combined traits, stalk yield and sugar yield were stable. These two varieties should be extended in commercial production.
