Abstract: 【OBJECTIVE】Yellow-seeded rapeseed (Brassica napus L.) is characterized with thinner seed coat and lower hull percentage, which in turn is correlated with higher oil, protein and lower crude fiber contents compared to black-seeded rapeseed from the same genetic background. The breeding of yellow-seeded rapeseed has become one of the main objectives in rapeseed breeding.To study the correlation among the quality characters of the same yellow-seeded rapeseed genotype with different crop conditions.【METHOD】Correlation analysis between the seed color and other main quality characters of GH01(yellow- seeded rapeseed genotype) was applied under 9 different sowingdate and planting density treatments.【RESULTS】The results indicated that yellow-seeded degree was negatively correlated with the oil content of embryo and seed(r=-0.6617 and r=-0.7458*separately). There was highly significantly negative correlation between oil content of embryo and protein content of embryo, but highly significantly positive correlation between oil content of embryo and that of seed(r=-0.9071**and r=0.8973** separately).【CONCLUSION】Correlation of yellow-seeded degree and the oil content of seed was various with the difference of the genotypes applied, while the correlation between oil content of embryo and protein content of embryo and the correlation between oil content of embryo and that of seed were steady.
