Abstract:

By exploring the changes in the research field of fresh-eating corn in China, grasping the research status and hot topics, and discussing the research frontiers and development trends, the study aims to provide theoretical reference for the research of fresh-eating corn. The research team used 1588 fresh-eating corn research literature in the CNKI database from 2010 to 2021 as the research objects, and carried out visual quantitative analysis based on CiteSpace software. In the past 10 years, the research development in the field of fresh-eating corn was stable, and the number of core papers published per year remained above 100. The high-yield authors were represented by LU Weiping, LIU Chunquan, LI Dajing, LU Dalei, etc., presenting single-line or radial team cooperation. The institutions to which the authors belong were mainly agricultural colleges and universities and scientific research institutes. Agricultural colleges and universities achieved more significant results in terms of the number of publications, and scientific research institutes had more advantages in the research and development of new varieties, and scientific research institutions and universities had close team cooperation. The analysis of emerging words indicates that haploid, super sweet corn, seed germination, genetic diversity, nutritional quality, flavor, folic acid, soluble sugar, etc. are the research trends. The core task of future fresh-eating corn research will be expanding the research coverage, breaking through the traditional limitations, exploring gene editing technology, transgenic technology, gene sequencing, single-celled sequencing, genome, proteins, transcription and other cutting-edge biotechnologies which are auxiliary means for traditional fresh-eating corn breeding research, and the focus will be on sweet and waxy corn and super sweet corn research. The future research should also highlight the quality and nutrition of fresh-eating corn varieties, and improve their resistance to diseases and insects, lodging, drought and other stresses. In the fields of food processing and feed research, more attention should be paid to the technology development of new processing equipment for extending the harvesting period and storage period of fresh-eating corn and maintaining the nutrition of corn during storage.
