Abstract

Seeds of sixty four genotypes of Brassica campestris L. (Toria) were analyzed for oil content and fatty acid composition. Oil content varied from 38.9% to 44.6%. Major fatty acids viz. oleic, linoleic, linolenic, eicosenoic and erucic acids exhibited ranges from 10.1% to 17.3%, 5.9% to 14.5%, 5.2% to 15.0%, 7.7% to 13.7% and 39.6% to 59.9%, respectively. Compared to the standard cultivar ITSA, four genotypes contained 5 to 8% lower content of erucic acid; and six genotypes contained significantly higher content of linoleic acid. Oil was positively correlated with erucic acid. The observed inverse relationship between linoleic and erucic acid contents might be utilized in breeding nutritionally better Toria cultivars with both high linoleic and low erucic acid contents.

摘要

对64个油菜（油用型）基因型的种子进行了含油量和脂肪酸组成分析。含油量在38.9%至44.6%之间。主要脂肪酸，即油酸、亚油酸、亚麻酸、二十碳烯酸和芥酸的含量范围分别为10.1%至17.3%、5.9%至14.5%、5.2%至15.0%、7.7%至13.7%和39.6%至59.9%。与标准品种ITSA相比，有4个基因型的芥酸含量低5%至8%；有6个基因型的亚油酸含量显著更高。含油量与芥酸呈正相关。观察到的亚油酸和芥酸含量之间的反比关系可用于培育营养更好、亚油酸含量高且芥酸含量低的油用型油菜品种。
