Jujube Germplasm SNP Data for 460 Samples with Core Markers

A genomic dataset from figshare, authored by Bingqi Shen and last updated in April 2026. It contains resequencing data for 460 representative jujube germplasms, identifying 585,131 high-quality SNPs and developing 100 core KASP markers. The study provides genetic resources for precise identification, conservation, and breeding of Ziziphus jujuba.

Use Cases

• Constructing DNA fingerprinting systems for jujube germplasm based on the 100 core SNP markers.
• Identifying core germplasm subsets for conservation based on genetic diversity analysis of 460 samples.
• Resolving intellectual property disputes over jujube varieties based on unique genotyping QR codes.
• Genotyping natural populations and hybrid offspring for discrimination based on the 23 validated KASP markers.

Strengths

• Contains 585,131 high-quality SNPs identified from 460 jujube germplasm samples.
• Developed 100 core SNP markers with a high average Shannon-Weiner index of 0.868 and PIC value of 0.412.
• Successfully validated 23 KASP markers with a 57.5% conversion rate for genotyping 96 samples.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a 4.6 MB DOCX document, which may require extraction or conversion for analysis.
