摘　　要：对不同海拔青稞(Hordeum vulgare L.)产量性状相关数据进行分析,分别计算不同品种产量性状的平均值及差异显著性水平;计算不同地区产量性状的平均值,并进行多重比较;估算其遗传方差,环境方差及遗传环境互作方差,比较遗传及环境对青稞产量性状的影响。结果表明,青稞的实粒数、千粒重在每个品种中差异都明显;玉龙地区的环境更有利于有效穗和产量的增加;千粒重主要受遗传控制,其次受基因与环境互作影响较大,环境影响最小。有效穗、实粒数、产量等产量性状受环境影响较大。The correlation data of yield traits of highland barley(Hordeum vulgare L.)at different altitudes were analyzed,and the average value and difference level of yield traits of different varieties were calculated. The average values of yield traits in different regions were calculated and multiple comparisons were made. The genetic variance,environmental variance and genetic-environmental interaction variance were estimated to compare the effects of heredity and environment on yield traits of hulless barley. The results showed that the grain number and 1000-grain weight of highland barley were significantly different in each variety. Yulong area environment is more conducive to effective spike and yield increase;1 000-grain weight was mainly controlled by heredity,followed by gene-environment interaction,with the smallest environmental impact. Effective panicle,grain number,yield and other yield traits are greatly affected by the environment.
