Abstract
The goal of these investigations was to estimate, on selected genetic materials, the correlations among economic (yield and grade index), morphological (topping height, plant height, internode length, leaf number, days to flowering, leaf length, leaf width, leaf L/W ratio, leaf area, leaf thickness and leaf weight) and chemical traits (nicotine, proteins, total nitrogen and ash). The trial was set up according to the RCBD in four replications at the experimental field of the Tobacco Institute Zagreb in Božjakovina from 1992 to 1995. Four-year average data among the mentioned traits were used for the calculation of correlations. According to the obtained results the investigated traits were mostly positively associated with each other. The economic and morphological traits, except days to flowering and L/W leaf ratio, were positively and mostly significantly correlated with each other. Mostly, strong to perfect correlations were estimated among these traits. Among economic and morphological traits, on the one hand, and chemical traits, on the other hand, correlations were mostly negative and nonsignificant.
