The objective of the investigation was to estimate interrelationship among rapeseed quantitative traits using simple regression coeffi cients, as well as to assess direct and indirect effects of specifi c traits to oil yield/ha via path analysis. Three year investigation was carried out including thirty rapeseed genotypes. The following traits were investigated: number of pods per plant, oil content, 1000 seed weight, pre-anthesis duration, post-anthesis duration, seed yield/ha
and oil yield/ha. Almost complete correlation was determined between seed yield/ha and oil yield/ha and strong between oil content and oil yield/ha. The strongest direct effects to oil yield/ha was estimated for seed yield/ha, whereas other investigated traits showed low or no effect to oil yield/ha.
