Abstract：In 2015,ten highland hulless barley varieties were assessed in a field experiment conducted in Qitai County,Xinjiang.The re-lationships 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 high-est yield of5 129.6 kg/hm2;12-900 came next with a yield of4 739.4 kg/hm2,followed by kunlun 14 with the yield of4 655.0 kg/hm2 .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 num-ber>1 000-grain quality>growth period>basic seedling number>plant height>spike number>ear length.
