Resistances
Resistances in varieties of our crops will be coded (please, see our coding list
on www.enzazaden.com for explanation), unless indicated otherwise.
Varieties claiming the same level of resistance against a specific pest or pathogen
may exhibit a different resistance response due to a different genetic
makeup of a variety.It is to be noted that if a resistance is claimed in a plant
variety it is limited to the specified biotypes, pathotypes, races or strains of the
pest or pathogen.
If no biotypes, pathotypes, races or strains are specified in the resistance claim
for the variety, it is because no generally accepted classification of the cited
pest by biotype, pathotype, race or strain exists. In this case resistance is only
claimed against certain not further specified isolates of that pathogen. New
biotypes, pathotypes, races or strains that may emerge are not covered by the
original resistance claim.
Immunity: not subject to attack or infection by a specified pest or pathogen
Resistance: the ability of a plant variety to restrict the growth and development
of a specified pest or pathogen and/or the damage they cause when
compared to susceptible plant varieties under similar environmental conditions
and pest or pathogen pressure. Resistant varieties may exhibit some disease
symptoms or damage under heavy pest or pathogen pressure.
Two levels of resistance are defined:
• High resistance (HR): plant varieties that highly restrict the growth and
development of the specified pest or pathogen under normal pest orpathogen
pressure when compared to susceptible varieties. These plant varieties
may, however, exhibit some symptoms or damage under heavy pest or
pathogen pressure.
• 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 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.
Susceptibility: the inability of a plant variety to restrict the growth and development
of a specified pest or pathogen.
Tolerance: the ability of a plant variety to endure abiotic stress without serious
consequences for growth, appearance and yield. Vegetable companies will
continue to use tolerance for abiotic stress.
