Abstract: In order to screen brewing sorghum varieties suitable for mechanized production in western Liaoning, 19 imported brewing sorghum varieties were used as tested materials, and the weight and weighted correlation degree of each character of each variety were measured by grey correlation degree analysis method. The results showed that the weight of each character of the tested brewed sorghum varieties was plant height > economic yield > spike length > growth period > 1000 - grain weight > stem diameter > grain weight per spike > weight per spike, when introducing and screening mechanized brewing sorghum varieties, plant height should be considered first, followed by economic yield. The weighted correlation degree of the tested brewed sorghum varieties was ‘Liaoza 19’ > ‘Ping shi 13’ > ‘Jiliang 2’ > ‘Jiza 124’ > ‘Jiza 137’ > ‘Jiza 142’> ‘Jiza 145’ > ‘Jiza 127’ > ‘Baiza 12’> ‘Jiza 138’> ‘Liaoza 37’ > ‘Tong za 108’ > ‘Baiza 11’ > ‘Jinuoliang 1’ > ‘Tongza 127’> ‘Baiza 14’ >‘Jiza 136’> ‘Baiza 13’ > ‘Jiza 14’, the top three in comprehensive production performance were ‘Liaoza 19’, ‘Pingshi 13’ and ‘Jiliang 2’. The results of grey correlation analysis and evaluation were consistent with production practice and could be used for comprehensive evaluation of brewing sorghum varieties.
