Abstract: Corn is the most widely cultivated cereal crop in the world，thus it possesses critical niche in agricultural production. Since the 80's of last century，the research of genetically modified corn（GMC）has been being a hotspot in the field of agricultural science. In order to understand the research situation of transgenic corn in the world，we analyzed the items that have great influence in this field，such as countries，research institutions，key journals，outstanding authors，and high cited papers，based on the papers of 10 years（2005 - 2014）on GMC collected in the Web of Science. With the content mining method，we extracted 10 core sentences in this topic，and analyzed the research hotspot of transgenic corn. The results showed that the United States and China led the world research level of GMC. China's scientific research institutions issued larger amount papers，but the papers issued from United States were in higher quality and caused larger impact in GMC field. The key journals publishing transgenic corn were concentrated in United States，Britain，Germany，Australia，Kenya，Ireland and Holland. Among the top 20 high cited papers，10 were from the United States. The research hotspot of the transgenic corn focused on the 4 aspects：the pest resistance，the anti-reverse，the risk assessment of environment，and the improvement of crop performance. Some studies，such as the use of RNAi technology against insects，shade-tolerant corn（resistant to high density），male sterility，etc.，could become the next hot topics on GMC in the future.
