- Good grain quality (especially cooking characteristics, color, shape, taste and aroma, and )
- High market price
- Optimum yield potential and stability over seasons
- Maximum tillering capacity for weed competition

- The right growth duration (maturity length) to match the season
- Avoid varieties that need to be planted or harvested earlier or later than surrounding rice fields to minimize pest damage (e.g., birds during maturation), and growth problems during times of harmful environmental conditions (e.g., late-maturing varieties running out of water)
