摘　　要：应用作物品种区域试验非平衡资料的分析方法,对9个参试啤酒大麦品种的6个主要性状2年8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,产量主要是试点效应为主,其次是品种×试点互作随机效应;②产量与全生育期,穗粒数之间协方差分量估计值为正,环境对这些性状的作用一致;③各参试品种比对照(港啤1号)增产显著;④保大麦6号、澳选1号、澳选2号和澳选3号这4个品种各个性状稳定性最好,比较适于在云南省大部分地区推广。Unbalanced data from 6 major traits of 9 malting barley varieties on 8 locations in two years were analyzed. The main results showed that： （i） The effects of environment on different traits were not the same, as the yield were mainly affected by locations and gene type × location interaction. （ii）The covariances effects among yield and entire growth period, number of grains per spilce were positive, and the effects of the traits on environment were consistent basically. （iii）The yield of these varieties increased significantly compared with control variety（ Gangpi 1 ）. （iv）These four varieties, Baoshan 6, Clipper, Aaoxuan 2 and Schooner, whose combined traits were better and stable, should be extended in commercial production in Yunnan province.
