Description:	Barley has a wide range of end uses. However, the technological characteristics expected from barley present different standards according to the destination of the cereal. Grain β-glucan content is the most important attribute for varieties destined for the food market due to blood glucose and cholesterol-reducing properties. High protein content, test weight, and huller rate may also add value to different end uses. In Brazil, the main destination for barley is malt production; however, not every lot achieves malting standards. To determine the quality of Brazilian barley for food industries, 9 covered barley cultivars and 8 hull-less barley breeding lines were studied. Thousand kernel weight (TKW), hectoliter weight (HW), huller rate (HR), protein, and β-glucan contents were analyzed. The hull-less breeding lines presented higher averages when compared to the covered group, except in protein content. Correlations between ?β-glucan and HW?, ?β-glucan and TKW?, and ?TKW and HW? were positive. On the other hand, ?HW and protein content? and ?β-glucan and protein content? presented a negative correlation. There are bromatological quality differences between Brazilian hull-less breeding lines and covered varieties. Brazilian barley germplasm presents great industrial potential, not only for malt production and animal feed but also for human food applications.Key words:β-glucan; hectoliter weight, Hordeum vulgare; naked barley; protein
