摘　　要：为明确新疆冷凉高海拔地区青稞主要农艺性状对产量的重要性,采用田间试验灰色关联度分析方法,对供试的10个青稞品种的主要农艺性状与产量关系进行了研究。结果表明:适宜于新疆种植的青稞品种为奇引2号、12-900、昆仑14号。其中,奇引2号的产量最高,达5 129.6 kg/hm2,其次为12-900和昆仑14号,产量分别为4 739.4 kg/hm2、4 655.0 kg/hm2。青稞产量与主要农艺性状的关联度由大到小排序为:有效穗数>千粒质量>生育期>基本苗>株高>穗粒数>穗长。In 2015,ten highland hulless barley varieties were assessed in a field experiment conducted in Qitai County,Xinjiang. The relationships between the yield and main agronomic traits of these varieties were determined by performing a grey relational analysis. Three varieties（ lead 2,12- 900,and kunlun 14） were shown to be suitable for planting in Xinjiang. Among them,lead 2 achieved the highest yield of 5 129. 6 kg / hm^2; 12- 900 came next with a yield of 4 739. 4 kg/hm^2,followed by kunlun 14 with the yield of 4 655. 0 kg/hm^2. Positive correlations were found between the main agronomic traits and yield of the tested hulless barley varieties. Their correlations varied in degree depending on the specific agronomic traits,which ranked from high to low in the following order： effective panicle number 1 000- grain quality growth period basic seedling number plant height spike number ear length.
