Megjegyzések:	Rapeseed is worldwide the 3rd, while regarding Hungary - beside sunflower - the 2nd most important oil crop produced. In our country winter oilseed rape is grown. Its cultivation area has been increasing since 1990; currently it varies between 200 and 250 thousand ha. The variety/hybrid palette has changed significantly during the past decade. As the result of this process hybrids are produced regarding the national average on 90%, while varieties on 10% of the total 230 thousand hectares production area. The experiment was set up at the Látókép Plant Production Research Site of the University of Debrecen. Three different sowing times were sown and three different plant densities were set in this year: 200, 350 and 500 thousand plants ha-1. Uniform nutrient supply and a row spacing of 45 cm were applied. Winter wheat was used as pre-crop. Plant physiological measurements were executed in the populations of the Arkaso, Hybridrock rapeseed hybrid and Ontario variety that were: relative chlorophyll content analysis (SPAD) and leaf area index (LAI) measurement. Relative chlorophyll content (SPAD) and leaf area index (LAI) were monitored in 7 different measurement times. We counted the plant densities before the winter and after the winter in the all experiment. The primary and secondary braniching, number of rape's kid, yield quantity have been determined as well in the present experiment, just as the interactions between these factors.
