Abstract:

In order to comprehensively grasp the research trends of waxy corn in China, the journal papers from 2002 to 2022 included in the CNKI journal database were taken as the research object, and the analysis was carried out from the aspects of the number of papers, institutions, authors, journals, highly cited papers, and keyword co-occurrence by Excel, SATI, and VOSviewer. The results showed that the average annual number of papers published in all Chinese waxy corn research journals was 229, with 343 core authors. The core journal had an average annual of 59 articles and 146 core authors. Shanxi Academy of Agricultural Sciences had the largest number of papers and Yangzhou University had the largest number of core journals papers. The largest number of articles published in Agricultural Science and Technology Newsletter was 254, accounting for 5.27% of the total number of documents. The core journal Maize Science had a maximum of 157 papers, accounting for 12.66% of the total number of papers. The highly cited papers were published in the journal with high academic level, such as Chinese Agricultural Science, Journal of Crops, and Maize Science with high citation of more than 50%, highlighting their core position and academic level. The keyword co-occurrence figures revealed that the waxy corn researches mainly involved the following aspects: (1) the cultivation of waxy corn, including the influence of cultivation modes and factors on the growth and yield of waxy corn; (2) the quality of waxy corn, including its starch characteristics and nutritional value; (3) germplasm resources and breeding techniques of new waxy corn varieties; (4) research on biological stress of waxy corn; (5) the impact of abiotic stress on the growth of waxy corn; (6) the problems and development strategies in the development of waxy corn industry; (7) the processing and preservation technology of waxy corn. In future waxy corn research, we can focus on creating high-quality waxy corn germplasm, quality research of waxy corn, research of efficient breeding technology systems and breeding high-quality new varieties, and standardized and efficient planting techniques.
