Abstract Cultivated peanut ( Arachis hypogaea L.) is an important legume crop with a large genome size but limited genetic diversity. Evaluating the variation among diverse germplasms using genome-wide molecular markers effective strategy to explore its diversity and thereby facilitate improvement. In this study, we introduced novel whole-genome genotyping (WGG) technique named dRAPD-seq (degenerate Random Amplification Polymorphic DNA sequencing), which relies on semi-specific PCR amplification by arbitrarily degenerate (AD) primer next-generation sequencing (NGS), demonstrated robust reproducibility high accuracy. Subsequently, applied investigate relatedness within population of 101 accessions identified low these accessions. Our phylogenetic tree, structure analyses, principal component analysis (PCA) indicated that could be clustered into three subpopulations, largely corresponding botanical types. conclusion, research not only cost-effective easy-to-conduct WGG method also provided valuable insights for utilizing in future breeding programs.
