Abstract: 【Objective】The purpose of this study was to introduce Chinese barley varieties to Mongolia for trial planting,so as to screen new varieties of high-yield and high-quality barley suitable for planting in Mongolia.【Methods】The experiment was implemented in Sumu Baonuer,Central Province,Mongolia,which was the main area of barley planting. There were 9 varieties in the experiment,including 6 barley varieties from Inner Mongolia of China（Mengpimai No. 1,Mengpimai No. 2,Mengpimai No. 3,Mengpimai No. 4,Mengpimai No. 5,and Mengpimai No. 6）,2 varieties from Russia（PA-459,PA-412/6,newly introduced varieties by Mongolian Agricultural University）,and a control variety from Mongolia（BURKHANT-1）. The growth period,growth indexes,yield traits,yield and grain quality indexes of the 9 varieties were analyzed and compared.【Results】Mengpimai No. 4 had the shortest growth period of 88 d and was an early maturing variety. The seedling retention rate of Mengpimai No. 5 was the highest（60.7%）,which was significantly higher than that of the other varieties（P<0.05）. The total panicle number of Mengpimai No. 5 was the highest（5 102 600 panicle/hm²）,which was significantly higher than that of CK（P<0.05）. The biomass of PA-459 was the highest（3 601.80 kg/hm²）,which was significantly higher than that of CK（P<0.05）. The biomass of Mengpimai No. 5 was 3 037.50 kg/hm²,which had no significant difference with that of PA-459（P>0.05）. The kernel number and weight of main panicle of Mengpimai No. 3 were 38.4 and 1.69 g,which were significantly higher than those of the other varieties（P<0.05）. The yield of Mengpimai No. 5 was the highest（1 580.1 kg/hm²）,which was 99.99% higher than that of CK（P<0.05）. The protein content of Mengpimai No. 5 was the lowest（14.7%）,which was suitable for both feeding and beer.【Conclusion】Mengpimai No. 5 had high yield and good quality for both feeding and beer,and it was suitable for promotion in Mongolia.
