[目的]为了探明油菜产量与其品质性状的关系。[方法]以三北98和油研599为材料，采用正交旋转设计研究甘蓝型优质杂交油菜产量与品质性状的相关。[结果]结果表明：①三北98和油研599油菜品种产量对品质性状的影响均以芥酸含量的变异系数最大，但两个品种的芥酸含量均低于2%，且三北98为0.90%，油研599为1.24%；棕榈酸含量的变异系数最小。②不同产量水平下各品质性状的差异，三北98以廿碳烯酸的含量存在显著差异，油研599仅有种子蛋白质的含量存在极显著差异，而两个油菜品种各品质组合性状间均无显著差异。③产量与品质性状的相关，芥酸、含油率与产量呈负相关，种子蛋白质、亚油酸、亚麻酸含量与产量呈正相关，且硫苷、棕榈酸、硬脂酸、廿碳烯酸与产量的相关系数较小，饱和脂肪酸、脂蛋总量、不饱和指数、不饱和脂肪酸、18碳脂肪酸总量、不饱和脂肪酸总量与芥酸链脂肪酸总量之比、油酸与亚油酸之和与产量呈正相关，芥酸链脂肪酸总量与产量呈负相关。④同一品种产量大幅度增加时，芥酸和含油量、芥酸链脂肪酸总量呈降低趋势，而种子蛋白质、亚油酸、亚麻酸、饱和脂肪酸、脂蛋总量、不饱和指数、不饱和脂肪酸总量、18碳脂肪酸总量、不饱和脂肪酸总量与芥酸链脂肪酸总量之比、油酸与亚油酸之和呈升高趋势。⑤种子蛋白质含量增加，饼粕品质变优；不饱和指数增加，油的稳定性降低；不饱和脂肪酸总量、油酸与亚油酸之和总量增加，有利于人体吸收利用的脂肪酸总量增加。[结论]为优质杂交油菜的高产保优栽培提供了理论依据。

[Objective] This study aimed to investigate the correlation between yield and quality traits of rape. [Method] Taking "Sanbei 98" and "Youyan 599" as ex-periment materials, correlation between yield and quality traits of Brassica napus L. cultivars was explored by orthogonal rotation method. [Result] The results showed that: ① In both the two varieties-Sanbei98 and Youyan599, erucic acid content had the largest coefficient of variation, but its average content was lower than 2% in both the two varieties (0.90% in Sanbei98 and 1.24% in Youyan599), and the palmitic acid content had the smal est coefficient of variation. ② In terms of the dif-ferences in quality traits at different yield levels, only the mean of eicosenoic acid content revealed significant difference in Sanbei98, and only the mean of seed-pro-tein content revealed significant difference in Youyan599, and there was no signifi-cant difference in any combined quality traits in both the two varieties. ③ The yield was negatively correlated with the erucic acid content or oil content, and posi-tively correlated with the content of seed-protein, linoleic acid, or linolenic acid, and the coefficient of correlation between the yield and either of the contents of glucosi-nolates, oleic acid, palmitic acid, stearic acid, and eicosenoic acid was smal er. ④when the yield of a variety increased considerably, there was a certain decreasing trend in erucic acid content, oil content, the total amount of erucic chain fatty acids (Ei & Er), while there was an increasing trend in seed-protein content, linoleic acid content, linolenic acid content, saturated fatty acids (SFA), the total amount of fat and protein (P & F), unsaturation index (IUFA), unsaturated fatty acids (UFA), the total amount of 18 carbon fatty acids (18-C FA), unsaturated fatty acids [UFA/(Ei &Er) ], and the sum of oleic acid and linoleic acid (Ol & Li). ⑤ When the seed-pro-tein content is increased, the quality of rape oil cake is also improved; when the unsaturated index is increased, the oil stability is decreased. The increase in the total amount of unsaturated fatty acids, oleic acid and linoleic acid helps to increase in the total amount of fatty acids absorbed by human bodies. [Conclusion] This study provides a theoretical foundation for the cultivation of high-yielding and top-quality hybrid rape cultivars.
