(Extract)Cifra Hartog Poly. (Cifra Hartog )Studying correlations between determined quality indices from laboratory tests were foundseveral important connections. Between hectoliter mass and protein content in grains it wasobserved a negative correlation with a distinct significant correlation coefficient of - 0.771and significant positive correlations were obtained separately with the assortment (0.750),starch content (0.872), yield of extract (0.686).Significant positive correlations were obtained separately and between variety and starch(0.565), respectively Kolbach index (0.641), Hartong index (0.616) and extract yield(0.891) between starch content and extract yield, with a coefficient of correlation r = 0.735.Significant negative correlations were made separately between HM and protein contentwith a correlation coefficient r = - 0.771, between variety and protein content with acoefficient of correlation r = - 0.501, and significantly correlation between starch contentand protein content r = - 0.395.2164. CONCLUSIONS- The thousand grain weight (TGW) is a very important indicator for the quality ofbarley for brewing, positively correlated with all other quality indicators.- Barley assortment influences positive all quality indicators except only proteincontent, which is negatively significantly distinctive correlated with this.- Between Kolbach index and Hartong index there is a very significant positivecorrelation (0.999), while between protein content and starch content there is asignificant negative correlation (- 0.395).- Therefore should be created varieties of barley with a TGM higher and with higherassortment, in order to obtain quality malt.- Tunika and Thuringia varieties have achieved the best results in our experience,cultivated on alluvial soil in Vădeni area.
