A bibliometric analysis of wild barley literature based on Web of Science and CNKI database

Wild barley is characterized by strong resistance, wide adaptability, and high nutritional value. It has great potential for use in food crop production, animal husbandry development, and environmental management. To understand the current research status and development direction of wild barley at home and abroad, this paper implemented bibliometric methods based on the Web of Science Core Collection (WOS) and China National Knowledge Infrastructure (CNKI) databases to analyze the annual publication volume, affiliated institutions, cooperative relations between countries, citation rate, keywords, and document sources of wild barley in the past 30 years. The results showed that there are many studies on wild barley at home and abroad, but due to geographical and cultural differences, the majority of Chinese studies are on wild barley are Hordeum brevisubulatum, while foreign scholars investigate H. spontaneum and its variants. In the past 30 years, the number of articles about wild barley in the two databases has been the same, showing a steady rise and reaching a peak in 2019. China, Israel, and Germany are at the forefront of the world in terms of the number of papers issued. Israel, Germany, and the United States are leading in the cooperative research. Among them, the University of Haifa and Inner Mongolia Agricultural University had the most published articles. Among domestic and foreign journals, “Acta Agrestia Sinica” and “Theoretical and Applied Genetics” issued the most articles. “Wild barley” and “barley” are keywords appearing more frequently, followed by “resistance” “stress” and “gene”. This reflects the current research hotspots of wild barley to a certain extent and provides theoretical support for the significance of the feed value, edible value, and ecological value of wild barley.
