Variety traits
Oryza sativa L.
The duration of rice development from sowing to full maturity, measured in days and dependent on the sum of active temperatures, photoperiodic response, and cultivation conditions.
In the reference 89 varieties crop Rice, where this is mentioned in the description.
The rice growing season ranges from 85 to 145 days, reaching up to 200 days in some global practices. In regions with temperate climates, such as the Kuban, breeding is focused on early-maturing forms with a ripening period of up to 125 days, which helps to mitigate risks associated with unfavorable weather at the end of the season.
The duration of this period is not fixed and depends on the accumulation of the sum of effective temperatures and day length. Development timing is also influenced by agrotechnical factors: improper selection of predecessors or irrigation regimes can extend the growing season by several days.
