Profile
JOY is one of a new generation of ultra early maize. Based on a strong flint genetic, these hybrids are really fast in vegetation, flowering and cob filling. They have a very high content of starch, and because of that a strong forage quality. DSV ultra early maize varieties have an outstanding youth development, also in cold areas.
-
Above average starch content
-
Wide leaves for high forage quality
-
Very good tolerance to cold weather conditions at juvenile stage
