Variety description

10 August 2026

The MAS 55WX maize variety was classified as very early. According to test results conducted from 2009 to 2010, the variety showed grain yields typical for the early ripening zone.

As of 2016, this variety was removed from the official French catalogue, and consequently, its official certification and registration within that country were terminated.
