摘　　要：应用AMMI模型对2002—2009年贵州省粳稻区域试验品种(组合)产量相关性状基因型与环境效应分析结果表明:基因型、环境、基因型与环境互作对考察的7个性状影响程度各不相同,生育期、有效穗主要受环境影响,株高主要以基因型效应和环境效应为主,穗粒数、结实率和千粒重同时受基因型、环境、基因型与环境互作影响,但环境效应相对较大,对产量影响的大小顺序为基因型与环境互作>基因型>环境。在贵州山区粳稻育种中,需针对基因型、环境、基因型与环境互作效应进行产量相关性状选择,以提高育种效率。Using AMMI model,we analyzed yield ＇ s relative traits such as genotype and environmental effects of varieties （combinations） of japonica rice regional trials of Guizhou Province.The results indicated that the effect degree of genotype,environment,genotype × environment interaction on 7 trials is different：Growing period,effective panicle mainly were effected by environment;Height mainly was influenced by genetic effects and environmental effects;Grain number,seed setting rate and 1000-grain weight are also influenced by genotype,environment,genotype×environment interaction.But environmental effects was relatively large.The influence order on yield was：genotype × environment genotype environment.In mountainous area of Guizhou Province,yield ＇ s relative traits such as genotype,environment,genotype × environment interaction should be selected in order to raise the breeding efficiency.
