“…BRS Brau and BRS Cauê showed statistical differences in β-glucan content when cropped in Passo Fundo, (RS) and Victor Graeff (RS) (Table 4), which reinforces some influence of environment in β-glucan content in these two varieties. Šterna et al (2017) and Wamser & Mundstock (2007) showed that protein content was significantly influenced by variety, year, and nitrogen fertilizer rates. High protein concentration in grains can be enhanced by using fertilizers that contain nitrogen, which means that the environment and crop management influence protein content.…”

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.
