Maize maturity group

Zea mays L. subsp. mays (Maize Group)

The maize maturity group is determined by the FAO index, a numerical indicator ranging from 100 to 999 used to categorize hybrids based on their biological characteristics and heat requirements.

In the reference 1 583 varieties crop Maize, where this is mentioned in the description.

The FAO index serves as a tool for the relative comparison of maize hybrids according to their growing season. The index values are divided into groups: early-maturing (100–199), mid-early (200–299), mid-maturing (300–399), mid-late (400–499), and late-maturing (500 and above). A difference of 10 FAO units under identical conditions corresponds to a change in the growing season of 1–2 days or a change in the grain dry matter content of 1–2%.

Selecting a hybrid based on the FAO index determines adaptation to the sum of active and effective temperatures of the region. Hybrids with a high index possess greater yield potential but require significant grain drying costs, whereas earlier groups are preferred for obtaining grain with low moisture levels. The maturity group also influences the choice of utilization for grain or silage, plant population density, and response to agronomic practices.
