High Resistance: describes 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. Highly resistant varieties may, however, exhibit some symptoms or damage under heavy pest or pathogen pressure*
IR
Intermediate Resistance: describes plant varieties that restrict the growth and development of the specified pest or pathogen, but may exhibit a greater range of symptoms or damaged compared to highly resistant varieties. Intermediately resistant varieties will still show less severe symptoms or damaged than susceptible plant varieties when grown under similar environmental conditions and/or pest or pathogen pressure.*
T
Tolerance: the ability of a plant variety to endure abiotic stress without serious consequences for growth, appearance or yield. A tolerant plant will usually show fewer symptoms than sensitive plant varieties when grown under similar conditions of abiotic stress.*
Immunity
Plant varieties which are not subject to attack or infection by a specific pest/ pathogen are considered immune.**
Resistance (R)
Plant varieties that restrict the growth and development of the specific pest or pathogen under normal pest or pathogen attack pressure when compared to susceptible varieties. These plant varieties can exhibit some symptoms or damage under heavy pest or pathogen pressure. Plant varieties with Resistant (R) are not immune to the pest/ pathogen.**
Intermediate Resistance (IR)
Plant varieties that restrict the growth and development of the specified pest/pathogen, but may exhibit a greater range of symptoms or damage compared to resistant varieties. Intermediate resistant plant varieties will usually show less severe symptoms or damage than susceptible plant varieties when grown under similar environmental conditions. and/or pest/ pathogen pressure, but may have heavy damage under heavy pressure. Plant varieties with Intermediate Resistance (IR) are not immune to pest/ pathogen.**
Susceptible (S)
The inability of a plant variety to restrict the growth and development of a specified pest/pathogen. Plant varieties that are susceptible will show damage when infected and are more likely to have heavy damage under moderate levels of pest/pathogen pressure.**
