如果将100个品种撕掉标签和包装,通过进行种子形态或者田间种植形态观察,把它们一一对号入座,辨别出各个品种名称,几乎没有人能够做到,那成千上万个品种就更不可能做到了。但利用DNA指纹技术识别就轻而易举了,一天就可以完成。“这就是DNA鉴定技术既准确可靠,又经济快捷的优势。”北京市农林科学院玉米研究中心主任赵久然的信心来自于他们团队20余年持之以恒关于玉米标准DNA技 If you tear up the 100 varieties of labels and packaging, through the observation of seed morphology or field planting morphology, put them one by one condemnation, identify the name of each species, almost no one can do that thousands of species even less May have done it. But using DNA fingerprinting is easy and can be done in a single day. “This is the DNA identification technology is accurate and reliable, but also the advantages of economic and efficient. ” Beijing Academy of Agriculture and Forestry corn research center director Zhao Jiu Ran’s confidence comes from their team more than 20 years of persistent standards on corn DNA technology
