Molecular markers are largely used to assist in crop improvement with the aim to achieve more favorable results in reduced time. In this study, we applied scientometric approaches to investigate and describe the application of molecular markers in genetic studies of common bean (Phaseolus vulgaris L.). A total of 671 articles, available on Thomson Reuters Web of Science database, published between 1991 and 2020, were analyzed, and it was determined that the USA and Brazil have the highest number of publications related to this subject. The main topics where molecular markers were used in common beans were fingerprinting, genetic diversity assessment, mapping, molecular marker development, marker-assisted selection, comparative genomics or evolution, and marker-trait association. They were also used to solve problems related to anthracnose (Colletotrichum lindemuthianum) and agronomic traits. As the genome sequence of common bean has been publicly available since 2014, SNP markers are frequently employed and their use is increasing, whereas other molecular markers are being bypassed.
