    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

      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.
