(2018) believe that this kind of technology is expected to achieve precise improvement, shorten the breeding cycle, and improve the production efficiency of sugarcane. 8 Conclusion Phylogenetic analysis is helpful to reveal the genetic diversity and evolutionary history of sugarcane and improve the productivity of sugarcane. By analyzing the genetic structure and diversity of sugarcane and its relatives, the researchers distinguished different genetic lineages and evolutionary patterns. Some studies have found that ancient hybrids such as S. barberi and S. sinense differ greatly from modern hybrids in genome composition and hybridization process, which has provided new directions for understanding the origin and adaptive evolution of sugarcane. Phylogenetic studies based on mitochondrial genomes enable researchers to more clearly elucidate the evolutionary relationships among sugarcane species. Breeders address the genetic basis of important agronomic traits by identifying species-specific alleles and optimize the management of genetic resources to improve breeding efficiency. The identification of genes related to environmental adaptation and selective clearing provided a new idea for the breeding of sugarcane varieties with high yield and stress resistance. Genome selection and association analysis have become important methods for researchers to achieve more accurate breeding strategies and screen for good alleles such as sucrose content and stalk yield. These results are useful for breeders to introduce good genes and enhance the genetic diversity of breeding populations. The phylogenetic and genomic studies of sugarcane will provide theoretical support for further analysis of the complex genome characteristics of sugarcane and improvement of cultivation level. The development of whole genome sequencing and reference genome construction technology can help us to understand polyploid traits and genetic structure of sugarcane more comprehensively. By combining genomic data with environmental variables, breeders can predict the performance of sugarcane varieties in different ecological climate zones and optimize breeding programs under specific conditions. Exploring the role of mitochondrial and chloroplast genomes in sugarcane evolution and adaptation may open up new ways for sugarcane variety improvement. With the progress of genomic technology, researchers will continue to enhance the ability to regulate the genetic traits of sugarcane, and it is expected to cultivate new varieties with more stress resistance and high yield potential in the future, and accelerate the development of the global sugar industry and bioenergy industry.
