The investigation of three wheat varieties (PKB Talas, BG Merkur and PKB Lepoklasa) carried out at experimental field and laboratory of Institute PKB Agroekonomik, during two years 2009 and 2010. Correlations between morphological and 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. Correlations were observed separately for three Institute PKB Agroekonomik varieties. 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 gr...ain weight per spike (>0.78), number of spikelets per spike and number of grains per spike (>0.79), and number of spikelets per spike and grain weight per spike (>0.73).
