摘　　要：为筛选具有生态适应性好的优质水稻,同时评价试点的代表性和区分力,采用GGE(基因型主效应及其与环境互作)双标图法综合分析12个杂交稻品种在6个试验点的产量及品质指标,并讨论试验点环境间的关系。结果表明:深两优5814、德优4727和T优6135表现出丰产、优质的特征。其中深两优5814多点平均产量10 096.25kg/hm^2,垩白粒率和整精米率分别为14%和56.5%且稳定性好。同时GGE分析表明,试验点中万州与梁平,秀山与南川紧密正相关。The yield and quality index of 12 hybrid rice varieties at 6 test sites were analyzed by genotype main effect plus genotype-environment interaction （GGE） biplots and the correlations among environments of different sites are discussed to screen high quality rice varieties with a good ecological adaptability and evaluate the representativeness and differentiating power of testing sites. Results： Shengliangyou 5814, Deyou 4727 and Tyou 6135 have the characteristics of high yield and high quality. The average yield, chalkiness grain rate and head rice rate of Shengliangyou 5814 are 10 096.25 kg/hm^2 , 14% and 56.5% respectively. GGE analysis shows there is a close positive correlation between Wanzhou and Liangping site and between Xiushan and Nanchuan site.
