Soybeans
How many different maturity groups are there?
There are 13 recognized maturity classes for soybeans. These range from maturity groups 000, 00, 0, and I through X. Those varieties with the lowest number designation (000 to IV) are considered indeterminate while maturity groups V through X are determinate varieties. Early maturity varieties (000 to IV) are adapted to the more northern climatic regions with the maturity designation increasing as you move south.
