Variety


Choose the most suitable high-yielding variety recommended for your rice growing environment.

Use locally adapted varieties to ensure good crop establishment and high yield with acceptable grain quality for market.

Considerations

  • • Good quality grain (especially cooking characteristics, color, shape, taste and aroma, headrice recovery) that should meet a farmer’s expectation in context of its marketability.
  • • Adequate yield potential and stability over seasons.
  • • Resistance or tolerance to the major diseases, insects and/or abiotic stresses (e.g., drought, flood) of the area.
  • • The right duration of growth to match the season. Avoid varieties that need to be planted or harvested early or late relative to other rice fields in the surrounding area to avoid:
  • • Increased attack from pests (e.g., birds during maturation), or
  • • growth problems during times of adverse environmental conditions (e.g., late maturing varieties running out of water)
  • • Adequate tillering capacity to shade out weeds and produce a sufficient number of tillers for optimum yields.
  • • Resistance to lodging under normal farmer management.
  • • Ensure variety is suited to the method of crop establishment and farmer management practices - e.g., some varieties are more suited to direct seeding than others.
  • • Ensure seed is available in sufficient amounts to meet local demand.
  • • Plant variety mixes in regions to maintain biodiversity and slow the spread of pests and the breakdown of varietal resistance.
  • • Use "good" seed to maximize yields.
  • • A variety should be tested over at least 3 seasons in farmers' fields to ensure suitability in terms of stability of yield and resistance to local pests and adaptation to local conditions.
  • • Evaluate new varieties using crop management that is similar to farmers' practice. For example, if farmers apply very little fertilizer, new varieties should not be evaluated under very high levels of fertilization. If farmers direct-seed, evaluation should not be done under transplanted conditions.
  • • Consult with farmers to ensure variety suitability before releasing a new variety.
  • • Grain quality, market demand and price need to be acceptable.
  • • Farmers should lower risk of new varieties by testing in just part of their fields.

To get the most of a non rice winter crop by ensuring timely planting, choose a shorter duration high-yielding variety or hybrid. Choose medium and long duration varieties for areas that stay wet till the end of December.

Choose your variety on the basis of the district, ecosystem and season in which it has to be grown.
