Variety description

10 August 2026

The SF 549 F1 hybrid is classified as early-maturing. Official documents confirm the registration of this hybrid, however, detailed information on its agronomic characteristics, including plant height, lodging resistance, and disease resistance, is absent.

Publicly available publications lack information regarding the connection of this hybrid to the Northrup King Co. company. When searching for data by the code SF 549, it should be noted that similar designations may be encountered in the context of other agricultural crops, such as kenaf.
