A model is presented that can accurately predict sterility of Environment-conditioned genic male sterility (EGMS) parent lines for producing hybrids as a function of sowing date and weather data.
- flowering date
- EGMS male sterility
- Cold sterility
- Total sterility
This model can be used to predict which sowing dates and locations will have 100% male sterility, which is essential when producing pure hybrids. It can also be useful for finding which sowing dates and locations will have<50% male sterility, which is needed to multiply the EGMS line.
