实现这一突破，吴桂琴团队用了近二十年的时间。 早在读书期间，吴桂琴跟随导师鉴定企业进口种鸡时才得知，我国的蛋鸡种源竟然80%以上要依赖进 口。而国内企业引种时，也总要看国际育种公司的脸色，时间、数量、质量和价格通通没有话语权。加 上进口种鸡有核心技术保护，不能直接用来育种，种源被"卡脖子"，自然也就没法保证鸡蛋的稳定供 应。 本报记者 骆倩雯 "我们可以很自豪地说，中国人每吃2枚鸡蛋，就有1枚来自京系蛋鸡。" 北京市华都峪口禽业有限责任公司副总经理 吴桂琴 中国人每吃2枚鸡蛋，就有1枚来自京系蛋鸡。女博士吴桂琴和她的团队，让中国有了自己的蛋鸡种源， 实现了"吃蛋自由"。 有一个场景至今还深深地刻在吴桂琴的脑海里。读博期间她到美国公派留学，参加了国际蛋鸡育种公司 的全球技术培训班。在参观实验室时，技术人员拿出一个试管，往里面滴了一滴液体后轻轻摇动，当出 现絮状沉淀后他神情骄傲地告诉大家"这就是鸡的基因组DNA"。"当时来自全球各地的客户都露出了惊 异的表情，赞叹不已，而我的内心却五味杂陈，因为这样的操作正是我读研期间熬夜苦干的常规动作， 压根不是什么稀奇的技术。"吴桂琴懂了，商业育种的核心技术并不是高不可攀，况 ...
