Abstract
In the paper, we studied genotypic differences in the process of winter triticale grain yield formation, in terms of yield determination by its components. We applied yield component analysis on four dwarf and 11 traditional (conventional stature) genotypes; an ontogenetic approach was employed to provide the appropriate view of this process. Using the k-means clustering procedure, the genotypes were grouped subject to similar yield structure (i.e., mean values and coefficients of variation of grain yield and its components, first clustering), similar correlation matrices among grain yield and its components (second clustering), and similar results of yield component analysis (third clustering). Based on the analysis, we attempted to provide an overall general view of determining winter triticale grain yield by its components. Thus, we elucidate that the pattern of influencing winter triticale grain yield by its components, as well as the pattern of co-relationships among these traits, cannot be explained by yield structure, and hence these two processes are determined by genotypic factors. The correlation among the traits (grain yield and its components) and the results of yield component analysis, on the other hand, were significantly related in the study, so they have similar genotypic sources.
