The hybrid is characterized by high productivity and a very high degree of self-compatibility, which ensures yield stability. In historical publications of the late 80s, it was mentioned as one of the new hybrid varieties intended for increasing the efficiency of agricultural production.
This hybrid should not be confused with modern commercial varieties named "Toledo" or "Toledo SU", which are intended for "Express/Sumo" technology and have a different breeding origin.
