Variety description

10 August 2026

This line was created as part of breeding programs in the late 1990s and early 2000s as part of a series of samples possessing the cold tolerance trait, as indicated by the abbreviation CT (cold tolerant).

The material was used exclusively in breeding trials to compare yield and adaptability. Information on CT 1 as a fully-fledged commercial variety with fixed morphological traits is absent from agronomic registers.
