Abstract: [Purpose/Significance] Wheat is one of the most important crops in the world, and its development of genetic and breeding technology plays an important role in the guarantee of global food security. Study about the patents of global wheat genetic and breeding technology as a new research field has a great significance on wheat yield and quality. [Method/Process] Patent analysis is used to filter, count and analyze relevant patent documents and convert them into usable information. During the development of wheat genetic breeding technology, a large volume of patent data have been generated. After data cleaning, 4 914 patents were obtained, of which 99.5% were invention patents and 0.5% were utility model patents. By using the methods of patent analysis and standardized data analysis, this paper performs statistical analysis on the patent documents published since 1977 collected from PatSnap database. Insights patent analysis system is used as a tool for patent analysis and valuation. The technical status, researching hotspots and developing trend of wheat genetic and breeding patents in the world can be studied from these following aspects, such as total number and trend of applied patents, distributions of countries' or regions' patents, technology composition, hot topics and patent value. [Results/Conclusions] The results showed the overall development trend of the global wheat genetic breeding technology patents, the research hotspots and the technology distribution and pattern. The research of global wheat genetic and breeding technology is gradually approaching the maturity stage; the growth trend of China's patent application is in the same line with the global patent application, and China has become the world's largest country of patent applicant. The large multinational companies are active institutions in this field, while Chinese applicants are mainly universities and research institutions. The research of disease resistance gene, herbicide resistance and insecticide resistance, molecular marker-assisted breeding, transgenic wheat are the hot technical topics at present; the main technology composition of wheat genetic and breeding technology patent in China is basically consistent with the global situation, but the technical emphasis has slightly difference. In this field China has been in line with the global technology strategy. High-value patents are mainly in the hands of large multinationals; the distribution of China's patent technology should break the regional limitations and take the initiative to participate in the global technological competition. The future prospect of wheat genetic breeding technology development in China was finally put forward.
