    Abstract:

    Variations in environmental conditions across different barley-producing regions and the selection targets for barley breeding have led to divergence of the brewing quality in different varieties. In this study， we conducted a comprehensive analysis of the brewing quality， including grain and malt quality traits， for 44 barley varieties that were bred from North America， Europe， and Australia， along with commonly grown barley varieties in China. This research has found that， the major varieties in various domestic regions have their malt quality comparable to foreign varieties differentially. For instance， the variety Longpimai 14 and Longpimai 18 from Northeast China are comparable to the imported European malting varieties. The Supi series from South region and the Ganpi series from Northwest China are comparable to the imported Australian malting varieties. The variety Zhongpimai 1 and Mengpi 3 from North China are comparable to the imported North American varieties. Compared with Chinese malting barley， the foreign varieties are mainly with lower content of β-glucan and higher of the extract. Moreover， the imported malting barley that grown in China showed their quality characters different from those grown in the original areas， as the malt diastatic power， kolbach index and β-glucan content can be affected significantly by the environment. However， most varieties from North American showed better adaptability to the growing conditions in China， without significant change on the malt quality characters in comparing with those grown at their original regions. The malt quality characters， including diastatic power and extract yield， are significantly correlated with the contents of protein， starch， and amylopectin in the grain. Given the measurement of grain quality characters are easier to handle， the grain protein， starch， and amylopectin contents can serve as initial targets for malting barley breeding. This study provided reference of malting barley varieties and guidance for the future selections of malting barley breeding in different domestic regions. It has significant meaning in improving the breeding efficiency and production of domestic malting barley.
