Protein content, starch content and selected malting parameters were assessed in 20 varieties of two-row spring barley. Mealiness was assessed using the Light Transflectance Meter (LTm) a hardness using the Single Kernel Characterization System 4100 (SKCS). Effect of the locality on mealiness and hardness was 87% (LTm) or 83% (SKCS). Significant correlations were found between LTm, SKCS and starch content, extract content in malt, Kolbach index, friability, and beta-glucan content in wort. High correlation was found between the two physically different methods used (LTm and SKCS).Protein content, starch content and selected malting parameters were assessed in 20 varieties of two-row spring barley.
