Description
263 first-generation seedling-derived half-sib progenies of turmeric were evaluated over two years (2024–2025) in Kozhikode, India. The study, authored by Akkurthi Neeraja, measured 17 vegetative, rhizome, yield, and dry recovery traits, identifying 53 superior progenies through multi-trait selection indices. Data was published on figshare under a CC-BY-4.0 license in May 2026.
Use Cases
Identify high-yielding turmeric progenies based on multi-trait selection indices like MGIDI and MTSI mentioned in the description
Analyze the genetic basis of yield components using heritability and genotypic coefficient of variation estimates provided
Model the relationship between vegetative growth and rhizome sink strength using the structural equation modeling path coefficients described
Assess trade-offs between total yield and dry recovery percentage using the reported correlation analysis
Strengths
Data covers 263 genetically distinct turmeric progenies, providing a basis for selection
High broad-sense heritability reported for key traits like total yield per plant (80.73%) and dry recovery (95.73%)
Analysis includes multiple statistical methods: Pearson correlation, stepwise regression, and structural equation modeling
Limitations
Column-level documentation is absent; field semantics must be inferred after download
Row count is unknown, which may limit suitability assessment
Data is from a single geographic location (Kozhikode, India), which may limit generalizability
