Rice Phenotyping for Breeding and Research
Measure morphology, color, chalkiness, and kernel integrity across lines, trials, and environments. Generate per-kernel images and structured outputs for statistical analysis in R or Python.
Quantitative rice phenotyping for research programs
Breeding and research teams often need more than a single average for an entire sample. Vibe measures individual kernels so researchers can compare complete trait distributions, identify outliers, and quantify variation within and between lines.
A consistent imaging protocol makes results easier to compare across operators, seasons, locations, and experimental treatments.
What can your program investigate?
Compare breeding lines
Quantify differences in kernel morphology, chalkiness, color, integrity, and trait distributions between lines.
Evaluate G×E and treatment effects
Apply a consistent measurement protocol across locations, seasons, replicates, and experimental treatments.
Verify grain phenotype after selection
Evaluate whether selecting for resistance, tolerance, biofortification, or another target trait affected the resulting grain phenotype.
Build reusable research datasets
Export per-kernel images, measurements, classifications, sample summaries, and metadata for statistical analysis or model development.
Measurements, defined
Kernel morphology
Measure length, width, area, aspect ratio, shape, and size distributions for individual kernels.
- Length and width
- Length-to-width ratio
- Long / medium / short class
Chalkiness and translucency
Quantify visible chalkiness and translucency using a rice-specific configuration validated for the study material.
- Per-kernel chalky / non-chalky
- Configurable area threshold
- Translucency scoring
Broken and intact kernels
Separate intact and broken kernels using configured dimensional rules and review the result at the individual-kernel level.
Color and appearance
Compare per-kernel color values, appearance distributions, and validated visual categories across samples.
- L*a*b* color values
- Milling / appearance categories
- Sample-level color distributions
Purity and off-types
Quantify visually distinct material and user-defined off-types according to the study's classification criteria.
Trait distributions
Compare complete distributions, sample summaries, variation, and outliers instead of relying only on one average value.
From sample to research-ready data
Scan the sample
Measure and classify traits
Compare lines, trials, or treatments
Export data, images, and metadata
The workflow preserves the connection between each kernel, its image, its measurements, and its sample metadata.
Compare lines, trials, and locations
Review per-kernel measurements, sample summaries, distributions, and classifications in the Vibe software. Export the results for independent statistical analysis and reproducible figures.

Methods and study configuration
Vibe measures visible rice-kernel morphology, color, integrity, and configured image-based characteristics at individual-kernel and sample levels.
Configure the workflow using representative material, consistent sample presentation, and reference categories appropriate to the study.
Frequently asked questions
Yes. Every kernel in a sample keeps its own record — measurements, classification, and image — exportable as CSV or Parquet with sample metadata, ready for R, Python, or another statistics tool.
Yes. The same imaging protocol applies to every sample, so per-kernel distributions from different lines, trials, seasons, or locations can be compared directly rather than only as single averages.
Yes. Kernels are imaged, not consumed or altered, so the same sample remains available for further testing afterward.
Yes. Chalkiness thresholds, size classes, and off-type or purity criteria can be configured to match a study's own definitions instead of a fixed default.
Vibe measures visible appearance, morphology, color, and kernel integrity.
