The investigation included mean values, coefficient variability and correlation coefficient of sage. On the basis of the results obtained, it was concluded that mean values of traits of sage were more during 2004. Performed investigations show high variability of chemical properties of sage. The variation range, i.e. large maximum and minimum limits, detected for: yield of dry herb, alfa-pipene, beta-pipene, camphene and manool, could be of a practical importance in sage breeding and selection. Besides, a significant effect of year on the expression of yield of dry herb and beta-pipene was observed. Prevalence of the negative and weak correlation aggravates selection of more qualitative genotypes of this medical plant. The analysis of correlation coefficient show that yield of dry herb and essential oil was positively and very significantly correlated (0.88**). Furthermore, high significant interrelation was detected between yield of dry herb and several components of essential oil. Interrelation between essential oil and its components was not significant and sometime positively and negatively. A very significant and negative correlation was determined between yield of dry herb and viridiflorol. Moreover, highly significant and negative correlation was detected between viridiflorol, onone hand, and camphene and alfa-pipene, on the other hand.
