Turmeric Half-Sib Progeny Yield and Trait Data from a Two-Year Field Trial

A two-year field trial (2024–2025) in Kozhikode, India, evaluated 263 seedling-derived turmeric half-sib progenies from five maternal accessions. The study, authored by Akkurthi Neeraja, measured 17 vegetative, rhizome, yield, and dry recovery traits to assess genetic variation and identify superior lines using multi-trait selection indices.

Use Cases

• Identify superior turmeric breeding lines based on multi-trait selection indices like MGIDI and MTSI mentioned in the description
• Analyze trade-offs between yield components and dry recovery traits based on the reported negative correlation
• Model the relationship between vegetative growth traits and rhizome sink strength using structural equation modeling results
• Assess broad-sense heritability for key agronomic traits like total yield per plant and dry recovery

Strengths

• Data covers 263 unique progenies and three checks, providing a substantial sample for genetic analysis
• High broad-sense heritability reported for key traits (60–97%), including total yield per plant (80.73%)
• Study design includes two years of field trials, allowing for environmental replication

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to a single trial location in Kozhikode, India
