Abstract
Sorghum (Sorghum bicolor (L.) Moench) is a crucial food, biofuel, and forage crop significantly affected by global climate change. Frequent extreme heat and drought markedly affect sorghum production, reducing production and threatening global food security. Several studies have been conducted on sorghum breeding, but a comprehensive bibliometric review is still lacking. Therefore, we retrieved articles published between 2007 and 2023 on sorghum breeding from the Web of Science and used various tools such as VOSviewer and CiteSpace to analyze them. The analysis showed that the number of articles on sorghum breeding has steadily increased during this period. A strong collaboration was observed among the United States, India, China, and Australia. The research results published by Australian scholars provide significant findings in this field and have been widely cited. Most articles were published in the ‘Theoretical and Applied Genetics’, ‘Crop Science’, and ‘Genetics’ journals. Drought stress, high sugar sorghum, temperature and soil mineral tolerance, and marker-assisted breeding were the research hotspots in sorghum breeding. Future CRISPR/Cas9 gene editing and MAS technology should be incorporated in sorghum breeding strategies to achieve precise environment-friendly breeding. New sorghum varieties with robust stress resistance, high yield, and tailored to specific use can be cultivated through genetic manipulation to effectively meet the needs of modern agriculture and promote green agriculture. Increasing the research, investment, and application of these advanced technologies can promote sorghum breeding and ensure global food security.
