The influence of stand density on formation and reduction of generative organs in winter rapeseed was evaluated in this study from the beginning of the flowering to the harvest. The results confirms that from the technological point of view it is appropriate to choose a thinner population of rapeseed. Starting with the stand density of 60 plants/square m we do not observe significant differences in plants during the generative stage, neither in the number of branches nor in the number of created generative organs. At this density a significant reduction of generative organs takes place, especially on the secondary branches. In the case of more dense populations, the differences in the number of fertile branches are visible only in the harvest. Nevertheless, it is more advantageous to support the creation of generative organs on primary racemes by agricultural interventions in order to achive high yields.
