随机挑选148份羽衣甘蓝种质资源和高世代材料,分析了成熟种子的含油量、蛋白质、硫苷和7种主要脂肪酸成分的表现特征及其相关性。结果表明:羽衣甘蓝成熟种子平均含油量为29.48%,平均蛋白质含量为45.13%,含油量和蛋白质总量为74.61%。硫苷含量的变幅最大,变异系数为31.72%。7种主要脂肪酸成分中,油酸和芥酸的含量较高,其次为亚油酸,棕榈酸和硬脂酸的含量较低。除硫苷含量和硬脂酸含量外,其余9个性状的表现均呈单峰正态分布。相关性分析表明,大多数性状间都具有显著或极显著的相关性,这与对甘蓝型、白菜型和芥菜型3种类型油菜的研究结果相一致。在羽衣甘蓝中存在一些优异的种质资源,通过筛选可以在油菜优质育种中加以利用。
148 kale germplasm resources and high-generation materials were randomly selected to analyze the performance characteristics and their correlation of oil content, protein, glucosinolates and seven main fatty acid components in mature seeds. The results showed that the average oil content of mature kale was 29.48%, the average protein content was 45.13%, and the content of oil and protein was 74.61%. The content of glucosinolate fluctuated the most, with a coefficient of variation of 31.72%. Of the seven main fatty acids, oleic acid and erucic acid were higher, followed by linoleic acid, palmitic acid and stearic acid. In addition to the content of glucosinolate and stearic acid content, the other nine traits showed a single peak normal distribution. Correlation analysis showed that most of the traits had significant or extremely significant correlations with the results of three types of rapeseed (Brassica napus, Brassica campestris and Brassica juncea). There are some excellent germplasm resources in kale, which can be used in the breeding of rapeseed by screening.
