Quality Control In Maize Seed Production

Eliminating undesirable plants:

Carefully examine your maize seed crop as it grows. You may find plants that look very different or flower much earlier or later than most other plants in the field.

These plants are called off-types and they should be removed—a process known as roguing—before pollen shedding starts. Most farmers do . . . → Read More: Quality Control In Maize Seed Production

Management Of A Seed Crop Production Field For Maize

Considerations for breeder and foundation seed multiplication

The half-sib method is commonly used to produce breeder and foundation seeds of maize. With this method, rows are arbitrarily designated as males and females in a ratio of 1 male to 2–4 female rows just before flowering.

All plants in the female rows are de-tasseled.

Recommended Seed Crop Production Practices For Maize

Breeding programs are continuously developing new maize varieties. These are often higher yielding than the older varieties or farmers’ varieties, and may have other value added traits, such as early maturity or better disease resistance.

To benefit from a new, improved variety, farmers should first obtain seeds. Seed production should be done in a . . . → Read More: Recommended Seed Crop Production Practices For Maize

Planting Maize

Planting times

In southern Queensland, mid-September to mid-October is the premium time. December provides another suitable opportunity, especially for dryland crops. In Moreton, maize is often successfully planted as early as mid- August. Latest plantings in these areas would occur in early to mid-January, due to likelihood of disease development in late summer/autumn.
