摘要
为了探明强冬性甘蓝型油菜种质资源的品质特性,以109份强冬性甘蓝型油菜种质资源为材料,应用近红外光谱检测法,对油菜籽粒含油量、硫苷、蛋白质及脂肪酸组成进行检测,分析了主要品质性状的变异和相关性。结果表明,强冬性甘蓝型油菜种质资源含油量、硫苷、蛋白质质量分数平均值分别为43.44%、41.51μmol/g、25.33%。在脂肪酸组成中,油酸质量分数最高,平均为55.50%,亚油酸、亚麻酸、芥酸、饱和脂肪酸质量分数依次为19.97%、11.95%、7.41%、 5.34%,亚麻酸含量显著高于双低甘蓝型油菜。芥酸、硫苷含量材料之间差异明显,变异系数分别为89.11、71.97;油酸、亚油酸、亚麻酸、饱和脂肪酸变异系数分别为15.62、11.71、9.32、8.02;含油量、蛋白质变异较小,变异系数均为6.56。相关性分析表明,强冬性甘蓝型油菜的含油量、硫苷含量、亚麻酸、芥酸、油酸、亚油酸之间极显著相关(r=-0.92~0.82)。聚类分析将109份资源分为两大类,第Ⅰ大类为高硫苷、高芥酸、低含油量种质,第Ⅱ类群为低硫苷、高含油量种质。
In order to explore the quality characteristics of strong winter rape(Brassica napus L.) germplasm resources, rape seed oil content, glucosinolate, fatty acid composition and protein were detected by near-infrared spectroscopy to analyze the variation and correlation on main quality traits of 109 winter rape(Brassica napus L.) materials.The results indicated that the average oil content, glucosinolate and protein content of strong winter rape were 43.44%, 41.51μmol/g, and 25.33%, respectively. Oleic acid content was the highest in all the fatty acid, with an average of 55.50%. The content of linoleic acid, linilenic acid, erucic acid, and saturated fatty acids were 19.97%, 11.95%, 7.41%, and 5.34%, respectively. Linilenic acid content was significantly higher than that of double-low rape. The content of erucic acid and glucosinolate was significantly different among materials, the coefficients of variation were 89.11 and 71.97, respectively. The variation coefficients of oleic acid, linoleic acid, linilenic acid, and saturated fatty acids were 15.62, 11.71, 9.32 and 8.02, respectively. The variation coefficients of oil content and protein were smaller and both 6.56. Correlation analysis indicated that between the oil content, glucosinolate content, linilenic acid, erucic acid, oleic acid, and linoleic acid of strong winter rape were extremely significantly correlated(r=-0.92~0.82). Cluster analysis divided 109 resources into two categories. The first category was high glucosinolate, high erucic acid, and low oil content germplasm, and the second category was low glucosinolate, high oil content germplasm.
