Genetic diversity and elite resources for ornamental traits of Chionanthus retusus

This dataset contains the supporting data for the manuscript “Genetic diversity and elite resources for ornamental traits of Chionanthus retusus”. It includes: 1) SSR (Simple Sequence Repeat) genotyping matrix for 105 Chionanthus retusus using 17 polymorphic markers; 2) Phenotypic measurements of 13 ornamental traits for 38 selected accessions. These data underpin the analysis of population genetic structure, isolation-by-distance, and elite germplasm selection presented in the manuscript.
