Field experiment was conducted to analyze the growth dynamics of the oilseed rape and the filling of pods in two types (cv. Brendy population and cv. Primus F1 hybrid). The variant of quantitative growth analysis for a single plant was chosen. It was found that the hybrid variety has a higher tolerance to biotic stresses that may occur (pests and diseases) and periodic drought (increased water storage capacity). However, it created a lower dry weight and lost the leaves earlier. Population produces more dry matter, earlier it establishes a fixed proportion of each organ within, but is exposed on spill on the seeds. As a result, the difference in the yield of the seed was 0,4 t ha-1 in favor of the hybrid. Hybrid oilseed rape breeding should strive to early establish a rigid proportion of the various organs of the dry weight of the plant.
