The seed color and other main quality characters of eight yellow-seeded rapeseed (Brassica napus L.) genotypes were studied in 4 different planting density and nitrogenous fertilizer treatments .The results showed that there are significant difference in seed color and other main quality characters of different genotype yellow-seeded rapeseed (Brassica napus L.). The main quality characters of yellow-seeded rapeseed (Brassica napus L.) were mostly determined by the genotype. Planting density, nitrogenous fertilizer and the interaction of them have significant effects on the main quality characters. The variation of the main quality characters of different genotype yellow-seeded rapeseed (Brassica napus L.) is different to the planting density and nitrogenous fertilizer treatments.
