Grapevine Berry Texture and Seed Development QTL Mapping from an F1 Population

An F1 population of 200 individuals from a cross between Raboso Veronese and Sultanina grape cultivars was phenotyped for berry color, weight, 28 texture traits, and seed morphology. High-density pseudo-testcross genetic maps for both parents contain over 1,200 SNP markers each. Quantitative trait locus analysis revealed a major QTL on Sultanina chromosome 18 with a LOD score up to 45 and explaining up to 65.49% of phenotypic variation for berry texture and seed traits.

Use Cases

• Identifying candidate genes for berry firmness based on QTL regions associated with 28 texture-related traits.
• Studying the polygenic nature of seed development deficiency using mapped loci for seed number and morphology.
• Analyzing the genetic link between berry softening and seed development status during ripening.

Strengths

• Phenotypic data includes 28 texture-related traits and 11 seed size and morphology parameters for 200 individuals.
• Genetic maps comprise over 1,200 SNP markers each for two parent cultivars.
• A major QTL explains up to 65.49% of phenotypic variation with a LOD score up to 45.

Limitations

• Dataset scale is limited to 16.0 KB, suggesting it contains summary or mapping results rather than raw phenotypic/genotypic records.
• Column-level documentation is absent; field semantics must be inferred from the description.
• Row count is unknown, which may limit suitability assessment for certain analyses.
