摘　　要：利用2008与2009年两年的浙江省油菜区域试验资料,采用作物品种区域试验非平衡资料的统计分析方法,分析了品种产量及其构成因素的方差分量,同时对参试品种进行稳定性分析。结果表明:‘037-77’品种产量较高,但与对照品种‘浙双72’没有显著差异;试点和年份×试点的互作效应对产量及其构成因素影响较大;除‘浙杂0603’和‘黔杂2630’对环境指数反应较敏感及‘J6’和‘ZY-10’一致性较差外,其余品种均表现出相似的稳定性。Variance components and the stability of yield characters of rape cultivars or lines tested in Zhejiang rape regional trials in 2008 and 2009 were analyzed with the analysis methods for unbalanced data from regional trial of crop variety.The results showed that the yield was mainly affected by the location and interaction between year and location.The yield of line ＇037-77＇ was higher than those of the others but there was no significant difference with that of the control（＇Zheshuang 72＇）.Except for ＇Zheza 0603＇ and ＇Qianza 2630＇,which were sensitive to environmental composite indexes,and ＇J6＇ and ＇ZY-10＇,which showed poor identity,the other cultivars or lines showed similar stability.
