This study conducted a meta-analysis of genetic markers associated with yield and quality traits in dragon fruit, revealing significant genetic diversity among different genotypes and their potential applications. Dragon fruit has gained increasing attention in the global market due to its nutritional value and economic benefits; however, breeding efforts still face challenges in balancing yield and quality. By integrating existing genetic data, this study highlights the potential of genetic markers such as simple sequence repeats (SSR) and inter-simple sequence repeats (ISSR) in identifying key loci associated with yield and quality traits. These markers facilitate the dissection of the genetic architecture of complex traits, providing a scientific basis for molecular breeding of dragon fruit. Furthermore, a detailed case study compared the antioxidant capacity and nutritional characteristics of specific genotypes, offering valuable references for cultivar selection.
