| Oilseed rape (Brassica napus) is a common crop in Denmark and mainly cultivated for its content of oil used for food and feed. The species is often genetically modified (GM), e.g. to herbicide tolerance or insect resistance. Spread of the inserted genes is likely to occur not only to the species itself, but also to its close relatives. The study showed a significant difference between phenotypes in the certified seeds and phenotypes in plants and in seeds in the field. The reason for this might be the presence of OSR volunteers from a previous crop surviving in the soil seed bank. This type of contamination is affected by e.g., harvest and post-harvest handling procedures (Fargue et al., 2003) and can consequently be reduced. More studies on... |

| Formålet med det foreliggende kapitel er at fremkomme med generelle oplysninger om, hvorledes uønskede planter eller gener kan påvises i en afgrøde eller i et frøparti. Da frø fra tidligere dyrkningssæsoner eller fra utilsigtet forurening i udsæd kan forekomme på en mark, er det specielt for GM afgrøder af betydning at påvise disse i en konventionel eller økologisk afgrøde. Frø fra GM-sorter bærer en eller flere genetiske markører, som kan genkendes ved hjælp af forskellige analysemetoder. Anvendeligheden af de forskellige analysemetoder såsom DNA-hybridisering, RFLP, PCR, RADP, ISSR, Microsatelliter samt immunologiske og isoenzymmetoder beskrives i detaljer for afgrødeplanterne almindelig rajgræs, italiensk rajgræs, rug, raps, hvidkløver og rødkløver. |
