Grapevine Berry Texture and Seed Development QTL Mapping Data

An F1 population of 200 grapevine individuals was phenotyped for berry color, weight, 28 texture-related traits, and 11 seed morphology parameters. The population was genotyped using Single Primer Enrichment Technology (SPET), yielding high-density genetic maps with over 1,200 SNP markers per parent. Quantitative trait locus analysis identified major-effect QTLs on chromosome 18 with LOD values up to 45 and explained phenotypic variation up to 65.49%.

Use Cases

• Identify candidate genes for berry texture traits based on QTL regions.
• Study the polygenic nature of berry mechanical properties using minor-effect QTLs.
• Investigate the link between seed development status and berry softening during ripening.
• Perform marker-assisted selection for seedless grape breeding programs.

Strengths

• Dataset includes 28 texture-related traits and 11 seed morphology parameters for 200 individuals.
• Genetic maps contain over 1,200 SNP markers per parent, providing high-density coverage.
• QTL analysis revealed loci with high LOD scores (up to 45) and high explained phenotypic variation (up to 65.49%).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
