The third cluster is composed of the following varieties: NS 525, Obzor, and NS
589. NS 525 and NS 589 are Serbian varieties with two-row spike morphology and
belong in the same cluster because they have the highest values for Na, P, Cu, Zn,
and Ni. The fourth cluster is consisted of eight cultivars. All six-row barley genotypes belong to this cluster, except Petra. Within the cluster there are two subgroups.
The first one was between Devinija and Kompolti korai, while the second was
between genotypes Somborac and Javor, which have six-row spike and Serbian origin.
10.4 Conclusion
This work aimed to study the macro- and microcontent in 30 winter barley varieties
with different origin, grown in the same environmental conditions, and to evaluate
the differences in mineral content in two- and six-row barley genotypes. The data
presented in this paper demonstrated considerable variations in macro- and microcontent in barley genotypes cultivated in the Republic of North Macedonia. From
the results it can be marked that two-row barley genotypes contained significantly
larger amount of tested elements compared to varieties which have six-row spike
