Abstract: Based on the data of several experiments, the correlationship and path analysis on the economic characteristics of hybrid oilseed rape-Rongyou No.3 are studied. The results are as follows:The direct path and partial correlation coefficients of planting densities and yield per plant to the yield per area are almost the same. Among the yield components of a single plant, the No. of effective siliquae is of the most importance, with the No. of seeds per siligua the second and the weight of 1000 seeds the third. The contribution of the yield of the first branches to the total plant is the greatest, with the main infloresence the second and the second branches the third. The positive correlationship between yield and No. of effective branches and negative correlationship between yield and braching height are found. There are positive correlationship between bio-mass and plant height, without significant correlationship between seeds yield and plant height.
