白菜分子育种全球专利竞争格局分析及对策建议

Pattern Analysis and Countermeasur Suggestion for Global Patent Competition on Chinese Cabbage Molecular Breeding

白菜作为我国主要蔬菜品种,目前在分子育种研究方面已取得显著成绩,但随着其在世界各地的引种种植,逐渐成为世界性蔬菜,引起各国研究者关注,因此,白菜分子育种的知识产权布局和竞争格局研究就显得尤为重要。针对白菜分子育种领域,以专利文献为研究对象,通过定性和定量相结合的情报学研究手段,借助DII、TDA等专利检索、数据分析工具,对白菜分子育种领域专利进行检索、分类、整理、分析。通过对该领域专利申请量的变化趋势、核心国家/地区、核心专利权人、技术分布、热点研究方向等内容进行分析研究,得出结论:近年白菜分子育种研究进入快速发展期;东亚三国是白菜分子育种研究的主要力量;高校和国立科研机构是白菜分子育种研究的主力军;基因克隆、鉴定、分子标记开发和种质资源创新是分子育种的主要研究方向。

Chinese cabbage is a major vegetable variety in China. At present,studies on Chinese cabbage molecular breeding has gained remarkable achievement. Along with its introduction and plantation in countries all over the world,Chinese cabbage has gradually become a globle vegetable and attracted the attention of worldwide resarchers.So studies on distribution of intellectual property about Chinese cabbage molecular breeding and the competition pattern becomes very important. Aiming at Chinese cabbage molecular breeding,taking pattent literatures as research object,adopting information science method of combining qualitative and quantitative research,using patent retrieval tools of DII,TDA,and data analysis tools,this paper retrieved,classified,tidied and analyzed the patent in the field of Chinese cabbage molecular breeding. Besides,the paper also studied on the variation trend,core countries /regions,core patent owners,technology distribution,and research hot spots of patent applications in this field. The results indicated that studies on Chinese cabbage molecular breeding had entered into a rapid development stage.Three east Asia countries were the major forces for Chinese cabbage molecular breeding. Universities and national scientific research organizations were the main research forces. Gene cloning,identification,development of molacule marker and germplasm resources innovation are the major research directions for molecular breeding.
