Ruditapes Variegatus Crossbreeding Performance for Heat Tolerance and Growth

A study on Ruditapes variegatus clams established a 3x3 diallel cross using inner shell color phenotypes (red, white, orange). The dataset likely contains measurements of heterosis, survival rates under heat stress, and heritability estimates for growth and thermal tolerance traits. The data was authored by Jinlong Li and last updated on May 28, 2026.

Use Cases

• Compare heterosis effects based on inner shell color crossbreeding combinations.
• Evaluate family-level heat tolerance using survival rates under thermal stress.
• Estimate heritability of growth traits at different developmental stages (e.g., day 30 vs. day 60).
• Identify high-performing clam families for selective breeding programs based on comprehensive performance clustering.

Strengths

• Specific heterosis percentages are reported, with mid-parent heterosis ranging from 3.56% to 32.42%.
• Heat stress survival rates are provided, with the top-performing combination showing a 64.86% survival rate.
• Heritability estimates are given for specific traits and time points, such as 0.56–0.69 for growth at day 60.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small at 291.7 KB, indicating limited scope.
