Tomato Fruit Shape QTL Mapping Data from Intraspecific Crosses

Data from a study mapping two suppressors of the OVATE gene (sov1 and sov2) in tomato using three intraspecific F2 populations. The analysis employed Bulk Segregant Analysis and high-throughput genotyping with the SolCAP Infinium Assay. The loci were mapped to intervals of less than 2.4 Mb on chromosomes 10 and 11.

Use Cases

• Perform QTL analysis on sov1 and sov2 loci to understand their genetic control over obovoid and elongated fruit shapes.
• Correlate genotyping data from the SolCAP Infinium Assay with fruit shape phenotypes across three F2 populations.
• Fine-map the sov1 locus on chromosome 10 and the sov2 locus on chromosome 11 using the provided genetic marker data.
• Investigate the suppression mechanism of the OVATE mutation using the segregation data from the extreme phenotypic classes.

Strengths

• Genetic mapping identified two specific QTLs (sov1 and sov2) with intervals refined to less than 2.4 Mb each.
• Analysis is based on three distinct intraspecific F2 populations, providing replication for QTL discovery.
• Uses a high-throughput genotyping platform (SolCAP Infinium Assay) for data generation.

Limitations

• Dataset size, row count, and specific column structure are unknown, limiting immediate analytical utility.
• The data is specific to intraspecific tomato crosses and the OVATE gene context, reducing generalizability to other species or traits.
• No sample data or file formats are provided, complicating assessment of data structure and accessibility.
