Caladium é um gênero majoritariamente ornamental e medicinal com elevado valor comercial. Estudos voltados ao melhoramento genético em Caladium vêm sendo realizados, incluindo o estudo da herança, micropropagação, caracterização morfológica, citológica, molecular e genômica, contudo, existem poucos estudos sobre a evolução no tempo e no espaço dos principais temas, autores, locais e tendências das pesquisas. Assim, objetivou-se neste trabalho analisar os avanços, limitações e tendências emergentes no melhoramento de Caladium utilizando análise bibliométrica. Foi realizada uma busca sistemática nas bases de dados Scopus e Web of Science, abrangendo publicações de 1992 a 2025. Foram identificados 141 documentos, dos quais 98 permaneceram após a remoção dos duplicados. Os dados foram analisados utilizando o pacote Bibliometrix no R, no ambiente RStudio, pela interface gráfica Biblioshiny. Os resultados revelaram uma flutuação no padrão de publicação de artigos, onde os EUA e a China destacam-se na produção cientifica. Observou-se uma evolução do melhoramento clássico para um foco robusto ligado herança, variação somaclonal e genética molecular nas últimas duas décadas. A ausência de uma explicação precisa sobre os mecanismos biológicos da variação somaclonal, aliado a falta de estudos relacionados a epigenética e as respostas morfofisiológicas pós-produção, representam uma lacuna no melhoramento de Caladium. Pesquisas futuras devem massificar estudos integrados entre as subáreas de citogenética, biologia molecular e melhoramento clássico, para acelerar o lançamento de novas cultivares para mercado ornamental.
