Tomato MAGIC Population Leaf Dry Matter and Phenolic Content Measurements

A dataset from Gloria Villanueva on figshare, last updated in May 2026, describes phenotypic measurements from 293 recombinant lines of an eight-way Tomato Multi-Parent Advanced Generation Inter-Cross (ToMAGIC) population. Leaf dry matter ranged from 6.90% to 23.20%, and specialized phenolic metabolites like chlorogenic acid ranged from 0.18 to 6.77 g kg⁻¹ FW, with total phenolic content averaging 3.65 g kg⁻¹ FW.

Use Cases

• Identify candidate genes for leaf dry matter content based on phenotypic variation among lines.
• Analyze correlations between different phenolic metabolites like chlorogenic acid, rutin, quercetin, and kaempferol.
• Perform genomic heritability analysis for traits such as chlorogenic acid content (H² = 0.66) and kaempferol (H² = 0.07).
• Conduct GWAS to find associations explaining phenotypic variation, as the study identified 6 significant associations.
• Select lines for breeding programs based on the nearly 20-fold range in total phenolic content (0.47–8.36 g kg⁻¹ FW).

Strengths

• Includes measurements for 293 recombinant tomato lines.
• Provides specific ranges and coefficients of variation for leaf dry matter (6.90–23.20%, CV=24.84%) and four phenolic metabolites.
• Reports genomic heritability estimates and 6 significant GWAS associations explaining 4.50% to 28.24% of phenotypic variation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is stored in a PDF file (6.8 MB), which may require extraction to a structured format for analysis.
