Abstract: In terms of clarify the relationship among stalk strength related traits and agronomy traits, correlation analyses were calculated in 10 selfing groups of rapeseed. Correlation analyses of stalk strength related traits indicates that mature stage was the best time for stalk strength assessment. During this stage, puncture strength had positive correlation with bending strength(r=0.78**), stem wall thickness had positive correlation with puncture strength, bending strength, and cellulose content(r=0.73**, 0.67**, 0.58**), but cellulose content had negative correlation with lignin content(r=-0.48*). Analyses between stem strength related traits and agronomy traits indicated that stem wall thickness was positively correlated with puncture strength and plant height(r=0.73**, 0.60**), Stem diameter was positively correlated with number of primary branch and yield per plant(r=0.66*, 0.53*), but negatively correlated with silique length(r=-0.65*). In conclusion, It indicated that there was a close relationship between stem strength related traits in Brassica napus, and the improvement of stem strength related traits would not cause huge loss of economic value.
