Description

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.

Input data:

  • a number of genetic parameters for predicting phenology and sterility
  • weather data (daily minimum and maximum temperature)
  • sowing date

Key outputs:

  • Flowering date
  • EGMS male sterility
  • Cold sterility
  • Total sterility

Examples

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.
