Agronomic Trait Diversity in Rice Genotypes from Tanzania

Tanzanian field trials assessed phenotypic diversity among 198 early-generation rice test lines and three check varieties. The study, authored by Lupakisyo Mwakyusa and last updated in April 2026, measured traits including days to flowering, panicle length, and grain yield. Significant genotypic differences were found, and cluster analysis grouped the genotypes into four distinct clusters.

Use Cases

• Identify superior rice genotypes for breeding programs based on cluster analysis results mentioned in the description
• Analyze relationships between agronomic traits like days to flowering and grain yield per row
• Assess genetic diversity for selection decisions in observational yield trials
• Support the integration of phenotypic data with molecular tools for improved selection efficiency

Strengths

• Includes data from 198 test lines and three check varieties, providing a substantial sample for analysis
• Reports statistically significant differences for key agronomic traits at the 1% and 5% levels
• Cluster analysis identified four distinct groups, with one cluster showing superior performance
• Data is openly available under a CC-BY-4.0 license

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 the single trial location in Tanzania
