Results are expressed as mean value±standard deviation, N=5. Different lowercase letters in superscript in a row represent statistically significant differences between mean values at p<0.05 obtained by one-way ANOVA and Fisher’s least significant difference (LSD) test for each harvest year separately. Two-way ANOVA factors: V=variety, Y=harvest year, I=interaction (V×Y); asterisk represents a statistically significant effect at p<0.05 by 2-way ANOVA; n.s.=not significant
