Controlled Environmental Agriculture (CEA) is a
collective term for indoor growing that leverages
technology, engineering and plant science to optimize
growing systems, plant quality and production
efficiency.
As early leaders in this area, Enza Zaden has a dedicated
CEA team on the ground, with an established greenhouse
vegetable portfolio, and a highly collaborative breeding
approach that involves extensive trialing under the precise
conditions of each grower’s system. Working together
with growers is how we’re helping to move the compelling
frontier of CEA forward.

Resistances
Resistances in varieties of our crops will be coded (see for
explanation our coding list at www.enzazaden.com.), unless
indicated otherwise. In case a variety is resistant to more than one
pathogen, the individual resistance codes will be separated by the
symbol “/”.
High resistance (HR) - plant varieties that highly restrict the growth
and development of the specified pest or pathogen under normal
pest or pathogen pressure when compared to susceptible varieties.
These plant varieties may, however, exhibit some symptoms or
damage under heavy pest or pathogen pressure.
• If in a resistance code of a certain variety reference is made to
certain strains for which the resistance is claimed this means that no
resistance is claimed to other strains of the same pathogen.
• If in a resistance code no reference is made to strains of the
pathogen for which the resistance is claimed this means that
resistance is claimed only to certain not further specified strains of
the pathogen and herewith disclaiming any guarantee that the variety
will not be infected by the said pathogen.
Intermediate resistance (IR) - plant varieties that restrict the growth
and development of the specified pest or pathogen, but may exhibit
a greater range of symptoms or damage compared to highly resistant
plant varieties. Intermediate resistant plant varieties will still show
less severe symptoms or damage than susceptible plant varieties
when grown under similar environmental conditions and/or pest or
pathogen pressure.
Tolerance (T) - the ability of a plant variety to endure abiotic stress
without serious consequences for growth, appearance and yield.
