Jujuba Germplasm Core Collection with 100 SNP Markers and DNA Fingerprints

A 2026 study by Bingqi Shen provides genetic data for 460 representative jujube germplasms. The dataset includes 585,131 high-quality SNPs, a core set of 100 markers, and DNA fingerprints for 92 core germplasm subsets. It supports the conservation, authentication, and breeding of Ziziphus jujuba.

Use Cases

• Constructing DNA fingerprint identification systems for jujube germplasm based on the described 100 core SNP markers.
• Analyzing genetic diversity and relatedness among jujube populations based on the resequencing data of 460 germplasms.
• Developing and validating KASP markers for genotyping based on the 23 successfully converted markers described.
• Resolving intellectual property disputes for plant varieties based on the unique QR code identification system mentioned.

Strengths

• Includes data from 460 representative jujube germplasms, providing a substantial sample base.
• Identifies 585,131 high-quality SNPs and a refined set of 100 core markers with high informativeness (average Shannon-Weiner index 0.868).
• The 23 successfully converted KASP markers demonstrated high discrimination in genotyping 96 samples.
• Released under a permissive CC-BY-4.0 license for broad reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analytical tasks.
• The 158.2 KB file size suggests the dataset is likely a summary or results table, not the raw sequencing data.
