KCR and HCD are erucic acid synthesis genes. In order to reveal the relationship between the synthesis of erusic acid and the quantitative expression of its functional genes, and to reveal the theoretic base of the breeding for high erucic acid content, the expression of KCR and HCD had been analyzed kinetically and quantitatively by using regular reverse transcription polymerase chain reaction and the internal standards of QuantumRNA18S during the growing period of high erucic acid content lines of Brassica Juncea.

研究应用常规RT-PCR(Reverse transcription polymerase chain reaction)的技术和QuantumRNA18S内标对芥菜型高芥酸油菜生育期内芥酸合成基因KCR、HCD基因的表达进行量化分析，了解芥酸的合成与功能基因量化表达的关系，为芥菜型油菜的高芥酸品种的选育提供理论依据。

The results indicated that the white flower was dominant over yellow and the erucic acid content was additively inherited. Both traits fit with a monogenic inheritance model, respectively. There were strong evidences to support the linkage relationship between the flower colour and the erucic acid content in the C-genome of B. napus with a recombination frequency of 4.8% in the DH population.

对亲本、F1、BC1、F2和DH 5个世代的花色及芥酸含量进行分析，结果表明：花色受单基因控制，且白花对黄花为显性；芥酸含量仅表现出一对基因的差异且具有加性效应的遗传模式。

Erucic acid is preferentially located at the 1,3 position, but more of it is present at the sn- 3 position.

芥酸优先分布于1，3位，但更多的则出现在sn-3位。

The results shows that there are a significant decrease of oil content and an extreme significant of erucic acid content.

结果表明，较低电压的处理可提高硫甙含量，显著降低含油量，而较高电压的处理可降低硫甙含量，极显著降低芥酸含量。

Main properties and uses, raw material production of erucic acid, preparation from rapeseed oil and derivative products development of erucic acid were introduced.

It was concluded that the germination and stem apexes growth of high-erucic acid materials presented much better than low-erucic acid materials under NaCl stress.

可以得出结论，供试的高芥酸油菜在萌发和离体培养阶段的耐NaCl性明显优于低芥酸油菜。

Current status and principal problems concerned in the production of biodiesel from rapeseed oil in China and other countries were introduced, based on which it was proposed to grow high-erucic acid rape in existing winter fallow fields and jointly produce biodiesel, erucic acid and its derivative products, and other highly valuable by-products such as glycerin and sterols from high-erucic acid rapeseed oil.

在介绍国内外菜籽油制备生物柴油产业发展现状和存在的主要问题的基础上，提出了利用现有冬闲田生产高芥酸油菜籽，以高芥酸菜籽油为原料联产制备生物柴油、芥酸及其系列衍生产品和甘油、甾醇类化合物等高值副产品对策，并从产品用途与市场需求潜力、企业经济效益、生产技术和条件、原料来源等几方面分析了这一发展对策的可行性。
