Variety traits

Maize maturity group

Zea mays L.

The maize maturity group is determined by the international FAO index, which classifies hybrids based on their relative earliness, heat requirements, and length of the growing season.

In the reference 5 061 varieties crop Maize, where this is mentioned in the description.

The FAO index is a numerical value where the hundreds indicate the maturity group and the tens indicate the hybrid's position within that group. The system distinguishes groups ranging from early-maturing (FAO 100–199) to late-maturing (FAO 500 and above), corresponding to growing seasons of 90 to 140 days or more.

This indicator serves as a key tool for selecting hybrids tailored to the agro-climatic conditions of a region to ensure the crop reaches physiological maturity. The FAO index is directly related to yield potential and grain moisture loss dynamics, which determines the intended use of the crop — for grain or silage.

General information about the subject — on the page Maturity group.
