Analysis of relationships between traits is an important stage in research. These results determine the decisions taken at further stages of research as well as those made when realising successive experiments. The paper presents results of an analysis of relationships between twelve traits of two types of maize (Zea mays L.) cultivars differing in leaf blade senescence rates: ES Palazzo and ES Paroli SG. Analysed traits: assimilation surface area (ASA), ear weight (EW), ear weight fraction (EWF), leaf area index (LAI), leaf area ratio (LAR), leaf weight (LW), leaf weight fraction (LWF), number of leaves (NL), plant weight (PW), specific leaf area (SLA), stem weight (SW) and stem weight fraction (SWF). Recorded results indicate positive correlations between: LW–SW, LW–PW, EW–SW, PW–SW, EW–PW, EW–EWF, SLA–LAR and negative correlations of LW–SLA, LAR–SW, PW–SLA, PW–LAR, SWF–EWF for both types of maize cultivars in all the three years of experiments.
