Research progress of plant polyploidy induction: A bibliometric analysis

To comprehensively understand the current research status and frontier development trends in plant polyploid induction and to obtain a better understanding of the latest research trends, we collected data from China National Knowledge Infrastructure (CNKI) and Web of Science (WOS) from 2000 to 2020. The literature on polyploid induction was systematically analyzed in terms of publication trends, frequency of citations, countries, periodicals, institutions, keywords, and burst terms. The analysis results show that in the research of plant polyploid induction, China, the United States, and Japan have made the most outstanding contributions. Most of this research focused on polyploid induction and identification methods. Of all the research institutions, Beijing Forestry University has the largest number of publications by far. Among these publications, “Euphytica” is in a leading position. Based on the research results of polyploid induction on a global scale and a comprehensive analysis of the hotspots and frontiers in this field, future research should focus on solving the following problems: 1) standardizing the evaluation procedure of polyploid induction, 2) solving the mosaic phenomenon during induction, and 3) achieving an in-depth understanding of the relationship between genome changes and new phenotype expression after polyploidization.
