Rapeseed with closed flowers: No more outcrossing?
In France, through mutation, rapeseed has been bred that can pollinate and fertilise itself even within closed flowers (i.e. cleistogams). This may represent a suitable biological system to prevent outcrossing of rapeseed. This would be of interest not only to keep genetically modified and convention rapeseed apart, but also to prevent unwanted mixing of rapeseed varieties with different traits. A safety research project has taken a closer look at cleistogamous rapeseed.

Genetically modified oilseed rape in Canada: Taking stock after ten years of cultivation
Although genetically modified oilseed rape is not yet grown in Europe, it now accounts for just under 90 percent of the total oilseed rape production in Canada, the world’s largest exporter of rape. The acreage under rape cultivation in Canada has been increasing steadily since it was first approved in 1995. According to reports from farmers and environmental organisations, ‘GM-free’ conventional and organic oilseed rape cultivation has virtually disappeared in Canada.more

Genetically modified canola in Australia: "Coexistence is a question of the market."
Since 2008, genetically modified (GM) canola has been cultivated commercially in two Australian states. How the coexistence of GM and conventional canola cultivations has been managed was the subject of an interview between BioSafety and Dr. Christopher Preston, Assistant Professor for Weed Management at the University of Adelaide.more

Oilseed rape and his big family
Oilseed rape belongs to the Brassicaceae or mustard family, which has many branches. It is related to several species found in Central Europe and can hybridise with some of them. more

Frequent flyers under surveillance
20,000 flights for 150 grams of honey - bees are renowned for their industriousness, and yet these avid pollen collectors are lazy. They make a beeline for the flowers nearest to their beehive, even if these are genetically modified. The biosafety researchers watch them do it. more

Cooking oil, animal feed, biodiesel
Rapeseed is a relatively new crop plant. Until a few years ago the oil pressed from the seeds was not edible. That has changed in the meantime. Modern rapeseed varieties yield not only high value cooking oils, the residues after oil extraction can also be used as animal feed. In the last few years primarily the growing demand for biodiesel has led to a sharp increase in rapeseed cultivation in Germany. more

Debate: Coexistence, a matter of concern?
Not only, are rape flowers extremely attractive to insects, but oilseed rape can also survive outside the cultivated area. Above all though, oilseed rape seeds are capable of surviving in the soil for years. Is oilseed rape capable of coexisting?
