Goji is a significant edible small-fruited shrub and has been a top-grade Chinese medicinal material since ancient times. In comparison to other crop species, very little information is available on goji as an important medicinal plant in terms of genetic resource conservation and development and germplasm improvement strategies. This comprehensive study illustrates the goji species-rich diversity, geographical classification, and domestic and international germplasm repositories, including their distribution and botanical features, all of which highlight the significance of the genetic architecture of this woody tree plant and provide a thorough understanding of the global distribution of goji berry germplasms, particularly in China, which can further facilitate germplasm collection for goji breeding. We also shed light on how goji berry germplasm has been improved by utilizing conventional and modern cutting-edge technologies, future research directions on the preservation and sustainable use of germplasm resources, and advances in genomic breeding strategies. This review will facilitate the development of novel goji germplasm repositories and support the strategic development of genetic resource management by prioritizing the acquisition of underutilized goji berries and advancing ex situ conservation through the application of contemporary gene bank techniques. Critical investigations have revealed gaps that need to be filled by breeders and researchers, such as the identification of wild germplasm and comprehensive genomic approaches, which could provide a basis for rapid breeding and fully utilize the genetic potential of goji berries to improve agronomic and economic traits.
