TL;DR: High-quality simple sequence repeat markers were screened and used to estimate the genetic base of a world-wide collection of 248 rapeseed (Brassica napus) inbred lines, and more allelic variations and a higher genetic diversity were observed in B. oleracea than in rapeseed.
Abstract: Assessing the level of genetic diversity within a germplasm collection contributes to evaluating the potential for its utilization as a gene pool to improve the performance of cultivars. In this study, 45 high-quality simple sequence repeat (SSR) markers were screened and used to estimate the genetic base of a world-wide collection of 248 rapeseed (Brassica napus) inbred lines. For the whole collection, the genetic diversity of A genome was higher than that of C genome. The genetic diversity of C genome for the semi-winter type was the lowest among the different germplasm types. Because B. oleracea is usually used to broaden the genetic diversity of C genome in rapeseed, we evaluated the potential of 25 wild B. oleracea lines. More allelic variations and a higher genetic diversity were observed in B. oleracea than in rapeseed. One B. oleracea line and one oilseed B. rapa line were used to generate a resynthesized Brassica napus line, which was then crossed with six semi-winter rapeseed cultivars to produce 7 F1 hybrids. Not only the allele introgression but also mutations were observed in the hybrids, resulting in significant improvement of the genetic base.

TL;DR: A project dealing with the improvement of the nutritional value of oilseed rape (Brassica napus) for human food applications was worked out and started in autumn 1999 as mentioned in this paper.

TL;DR: In this paper, a procedure for the determination of total phenolic acid content in rapeseed/canola was developed by combining and modifying two currently used methods, which consists of refluxing the sample with acidic acetone, alkaline hydrolysis of esterified phenolic acids followed by acidification, extraction with ethyl acetate/ ethyl ether, and colormetric measurement using Folin-Denis reagent.

TL;DR: In this paper, a process for the diffusion extraction of glucosinolates from rapeseed was described, based on the principle that low molecular weight glucosins will passively diffuse through seed membranes which retain proteins and triglycerides.
Abstract: A process is described for the diffusion extraction of glucosinolates from rapeseed. The detoxification procedure is based on the principle that low molecular weight glucosinolates will passively diffuse through seed membranes which retain large molecules such as proteins and triglycerides. The diffusion rates of glucosinolates, sugars, polyphenols and some N compounds were affected by extraction time and temperature, agitation, seed to solvent ratio and pH of the aqueous medium. Five or six 1-h extractions with 0.01N NaOH at 60°C were sufficient to remove all but traces of the glucosinolates present in turnip rape and rape. Boiling of the seed before aqueous extraction was necessary to control the myrosinase activity and maintain the sulfur content of the oil at less than 10 ppm. The diffusion extracted rapeseed contained a higher proportion of oil and crude fiber but lower percentages of crude protein, ash and N-free extract than control samples. The detoxified rapeseed could be used directly in feeds and foods or further processed into a meal, flour, protein concentrate or isolate.

TL;DR: The results indicate that plant material from either napus or rapa species could be used in breeding for increasing erucic acid content, and indicate that a large overall market potential exists for development of annually renewable domestic sources of erucing acid.
