Clematis Hybrid Floral Trait Inheritance Patterns and Heterosis Measurements

A 2026 study by Xinli Zeng analyzes inheritance patterns of ten floral and vegetative traits in Clematis interspecific hybrids. The dataset includes measurements for traits like flower stalk length, flower diameter, sepal dimensions, and blooming period, analyzed using heterosis and a major gene plus polygene mixed genetic model. It is published under a CC-BY-4.0 license on figshare.

Use Cases

• Modeling inheritance of quantitative floral traits based on the described major gene plus polygene mixed genetic models.
• Estimating heterosis for breeding compact Clematis cultivars based on mid-parent heterosis values for traits like leaf blade length and blooming period.
• Assessing genetic control of ornamental traits based on the reported major gene heritability exceeding 88% for nine of the ten traits.

Strengths

• Genetic analysis identifies specific optimal inheritance models (e.g., 2MG-AD, 2MG-A) for each of the ten measured traits.
• Major gene heritability for nine traits exceeds 88%, indicating strong genetic control under the study conditions.
• Dataset is small (12.2 KB), facilitating quick download and inspection.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale analysis.
• Column-level documentation is absent; field semantics must be inferred from the description after download.
• Data reflects a specific experimental cross between two Clematis species; generalizability to other species or environments is unknown.
