Variety traits
Rice Maturity Group
Oryza sativa L.
The rice maturity group is determined by the length of the growing season from emergence to maturity, which ranges from 90 to 165 days. The classification of varieties is based on these timeframes and the cumulative active temperature requirement of 3300 to 4500 °C.
In the reference 223 varieties crop Rice, where this is mentioned in the description.
For rice, the length of the growing season is a key varietal trait; however, unlike other cereal crops, rigid numerical boundaries for maturity groups are not standardized. The earliness of a variety is evaluated by recording plant phenological stages such as emergence, tillering, heading, flowering, and maturity.
The choice of maturity group is a determining factor in cultivation strategy, allowing the crop's life cycle to be adapted to the frost-free period and temperature regime of a region. Maturity dates directly influence the water management schedule, fertilizer application, and determine the biochemical composition of the grain, including amylose and protein content.
