Resistances Resistances

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 pestor pathogen pressure when compared to susceptible varieties. These plant varieties may, however, exhibit some symptoms or damage under heavy pest or pathogen pressure. Variety name Resistances Size Growing Processing Season system (P) HR IR S M L Heads (H) Sp Su Au Wi Wildebeast | STANDARD Bl:16-36EU/1-9US/Nr:0 LMV:1 x OF P / H • 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 samepathogen. • 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 saidpathogen. Disclaimer 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.
