Utilizing molecular marker techniques, we gained profound insights into the genetic diversity of the wild rice genome, providing a valuable genetic foundation for breeding. Wild rice exhibits exceptional adaptability, and its performance in terms of stress resistance and environmental adaptation lends theoretical support to its application in breeding. Particularly in rice breeding, harnessing wild rice genes has emerged as a crucial avenue for enhancing both crop yield and stress resistance. The utilization of gene-editing and transgenic technologies presents innovative possibilities in this regard. On the conservation front, emphasis is placed on strengthening the protection of the native habitats of wild rice, advocating for the establishment of a global wild rice gene bank, and fostering public awareness through education and outreach. This comprehensive understanding provides scientific guidance and a sustainable development path for future rice breeding and the preservation of wild rice germplasm resources. Keywords Wild rice (Oryza rufipogon); Genetic diversity; Adaptability; Rice breeding 1 Introduction Oryza rufipogon is a close ancestor of cultivated rice and is a national level II protected plant. During the long evolutionary process of wild rice, due to the complex geographical environment and various ecological factors, rich genetic diversity has been formed, which contains abundant excellent gene resources, such as disease and insect resistance, stress resistance genes, efficient nutrition, high yield and quality, male infertility and other genes. These excellent genes are the important material basis and "resource treasure trove" for solving the many problems in current rice production (Yang et al., 2022). Wild rice germplasm resources, as a member of the rice family, have unique genomic composition and biological characteristics. In this study, we will provide a detailed definition and overview of the germplasm resources of wild rice, clarify its position in the rice family, and its relationship with cultivated rice. On this basis, we will use modern genetic methods such as molecular marker technology to systematically determine the genetic diversity of wild rice germplasm resources and analyze their genetic structure in different populations. This will provide necessary data support for us to gain a deeper understanding of the wild rice genome. This study conducts a detailed analysis of the genetic diversity of wild rice and uses molecular marker technology to deeply study the genetic differences between different populations of wild rice, thereby revealing their adaptive strategies in the evolutionary process. In addition, we will also focus on the impact of genetic diversity on the stress resistance of wild rice and explore its adaptability in different ecological environments. On the one hand, this will help us better understand the ecological significance of wild rice, and on the other hand, it will provide a theoretical basis for its potential application in stress resistant breeding of cultivated rice. By studying its ecological adaptability, we can understand the growth and reproduction strategies of wild rice under different habitat conditions, providing reference for its application in cultivation environments. Examining the impact of human factors on its adaptability, especially the impact of human activities on the habitat of wild rice, is crucial for developing effective protection and utilization strategies.
