Abstract: ： In order to utilize the rapeseed （Brassica napus L.） germplasm resources effectively and provide theoretical basis for the breeding new varieties,95 genetic resources from different countries were selected and analyzed by agronomic traits and quality traits for genetic diversity and correlation. Results showed that there were abound genetic diversity in these germplasm resources. The coefficient variations were from 6.66% to 111.88%. The correlation and the partial correlation analysis revealed that plant height was highly positive significant with the effective branching height and the length of main inflorescence. Effective pod number per plant was highly positive significant with first effective branch number and the pod number of main inflorescence. Effective branch number was highly negative significant with length of main inflorescence. It was highly positive significant between glucosinolate and erucic acid. Oil content was highly positive significant with erucic acid, but highly negative significant with protein. The correlation coefficients were 0.76、0.38、0.52、0.50、-0.30、0.80、-0.63、0.33,the partial correlation coefficients were 0.90、0.73、0.46、0.47、-0.56、0.85、-0.57、0.58. Length of main inflorescence and effective branching height are not significant correlation coefficient, but the partial correlation coefficient is highly negative significant.
