Genetic potential and breeding strategies in Psidium cattleianum Sabine: a bibliometric analysis

The genus Psidium, which includes a variety of tropical and subtropical fruit-bearing species, is notable for its broad genetic diversity, particularly in Psidium cattleianum, a species whose potential remains largely unexplored. This study aims to explore the genetic diversity of Psidium fruits through a global literature review and bibliometric analysis, using the Web of Science© database and VOSviewer software to identify breeding strategies focused on fruit production in P. cattleianum. The dominance of research on P. guajava highlights the urgent need to expand studies to other species within the genus, especially P. cattleianum. Techniques such as germplasm conservation, analysis of reproductive systems, and the selection of desirable traits are crucial for advancing the breeding of P. cattleianum, with particular attention to fruit quality and productivity. Developing more productive and disease-resistant varieties can significantly increase productive efficiency and promote the commercial cultivation of the species, adding significant value and creating new opportunities for sustainable agriculture and crop diversification. Despite recent literature focusing on P. guajava, there is a significant gap in studies on P. cattleianum, especially in Brazil, where methods such as germplasm conservation and the exploration of genetic diversity can be pivotal for fruit breeding. It is essential to expand research and genetic improvement of P. cattleianum to unlock its full potential, promoting its incorporation into breeding programs that enhance the quality and productive characteristics of the fruits, thus increasing their use and market value.
