In a set of 20 spring barley varieties tested in the years 1990 and 1991 through analysis of correlations between grain yield and yield components we have verified the method of regression analysis. According to the years and averages, two models of multiple regression were created (original with 10 characters and adjusted (M sub(K)) with five characters). On average, over two years, M sub(K) characters (number of days sowing-maturity, lodging, spike number per m sup(2), thousand grain weight, malt extract content) were convenient for grain yield estimation (r equals 0.940 sup(++))
