Sažetak

Research was done on three Institute PKB Agroekonomik wheat varieties (PKB Talas, PKB Vizeljka and PKB Arena), during production years 2014 and 2015. Correlations between production traits of plants: number of shoots, number of spikelets per spike, number of grains per spike, 1000 grain weight and grain weight per spike, were studied. The manner of preparing data for calculating correlations influences obtained correlation values, and these values can differ substantially. Correlations calculated based on aggregated data are higher than those based on all data. Correlations differ for different varieties, which is logical, because each variety has a different genotype and specific genes forming various interactions. Taking into account all three varieties, high and positive correlations were found between: number of grains per spike and grain weight per spike (>0.79), number of spikelets per spike and number of grains per spike (>0.80), and number of spikelets per spike and grain weight per spike (>0.74).
