Luo M.T., and Li Z.G., 2025, Genetic diversity and trait discovery in pineapple germplasm: a meta-analysis approach, International Journal of Horticulture, 15(3): 105-112 (doi: 10.5376/ijh.2025.15.0012)

In this study, we used a meta-analysis to describe the genetic diversity of pineapple germplasm resources and the results of excellent traits mining, revealed the population structure differences among different germplasm types and geographical sources, analyzed the integration rule of QTL related to high Brix traits through a case study, and proposed a breeding strategy based on molecular markers and genome selection. The results show that genetic variation exists between different regions and varieties of pineapple, and molecular markers are very effective in assessing germplasm diversity and trait associations. This study is expected to provide scientific basis for the targeted breeding of high-quality pineapple varieties and efficient utilization of genetic resources, and promote the development of pineapple industry.
