Changes in Erucic Acid Concentration of Rape Seeds in Advanced Generations

This study was carried out to determine the extend of changes in erucic acid concentration of rapeseeds which were grown in Carsamba and Bafra Plains of Central Blacksea Region. In addition to field experiments, the same experiment was conducted in the greenhouse to avoid polen transfer from other sources. The first material used was 00 type rapeseed cultivars. In order to ensure a good result, the experiment sites were selected based on the intensity of other Brassica species (B. oleracea, B. rapa, B. nigra). The harvested rape seeds was the seed material of following year. Erucic acid content was measured for seeds obtained each year. The erucic acid content for three genarations showed that it was much lower than the limits for health (0.04 %).
