Visualizing the data
Provide the breeding program with a software tool to visualize consumer preference for rice grain quality and demand
Tableau

Assumptions
Consumer preference data is representative
Consumption is representative of the demand
Consumption per capita is the same for urban and rural population and regardless of poverty level
![Page 38: Consumer preference and demand for rice grain quality](https://reader035.fdocuments.us/reader035/viewer/2022062404/55358f9e5503465a698b463a/html5/thumbnails/38.jpg)
Future work on market segmentation
• Consumer preference for rice varieties– Conduct market survey
• Producer preference for rice varieties– Based on existing farm surveys – Identify characteristics of preferred rice varieties in terms of:
• Grain quality• Agronomic traits: yield potential, maturity• Stress tolerance: abiotic (temperature, drought, submergence),
insect and disease reaction
• Maps of major rice growing areas suffering from abiotic and biotic stresses– Temperature stress (cold, day-time and night-time heat stress)– Drought, submergence/flooding– Pest and diseases
