Abstract

The paper presents data about the structural elements analysis of winter wheat spike. Through cluster analysis were established different variety groups – parents and hybrids that are similar on the high index value basis. Correlation analysis showed that each cultivar or hybrid has different degree of connection between the investigated elements. Grain weight per spike correlates particularly with the 1000 grain weight. In most cases the production elements were inherited in F1 as positive dominance or supra-dominance.
