Herbicide-tolerant crops in agriculture: oilseed rape as a case study

摘要: Oilseed rape has been modified extensively by conventional breeding for the production of varieties useful human consumption (blended vegetable oil and margarine) industrial processes (rubber additives high-temperature lubricants). Because much is now known about its genetic biochemical composition, it an obvious choice modification at forefront commercial development genetically (GM) or transgenic crops. Around world, increase in plantings all crops rapid. In 1996, 1.7 million hectares were planted, but 1998 this figure had jumped to 27.8 ha. The area year 2001 likely be 50 With possible introduction into European agriculture, essential that associated farming practices employed are appropriate their growth, both from a environmental viewpoint. Some first those carrying agronomic traits, e.g. herbicide tolerance transgenes. However, before full commercialization occurs, important questions need answered. How these new incorporated existing cropping practices? will change current use profile given crop? Do herbicide-tolerant enhance impede integrated pest management schemes? What uptake such agriculture? ecological implications introduction? Are there effective measures control spread transgenes wild relatives? This paper addresses questions, with special emphasis on oilseed UK, includes examples other countries where appropriate.
