Application of molecular markers in palm genetics and breedingAbstract: With the rapid development and application of molecular markers, it has become an important tool for palm genetic improvement, which plays an important role in shortening the breeding process and speeding up the selection and cultivation of varieties. The application of common molecular markers in palm plant genetic diversity and genetic relationship analysis, molecular markers of important traits in palm plants, and genetic map construction are reviewed. Finally, the application prospects of molecular markers in palm plant breeding are pointed out.
