*Notes regarding resistences to nemathods – Soil temperatures higher than 27 °C and other stress factors might cause a decrease of resistance until its annihilation. Generally talking it necessary to make disinfestation/extermination before transplanting and during cultivation, especially in soils where last culture suffered attacks by this pathogen.
Resistance: it is the variety capability to limit the growth and development of a specific harmful organism and/or the damage it causes, regarding varieties susceptible and put in the same environment and pressure conditions of/as the harmful organism. Anyway resistant varieties might show some pathological or damaging symptom if set under heavy pressure of the harmful organism.
High/heavy resistance (HR**): The variety is able to limit heavely the growth and development of a specific harmful organism, in normal conditions of infective pressure when it faces with susceptible varietiesi. Anyway, these varieties might show some symptoms or damage under heavy pressure of the harmful organism.
Intermediate resistance (IR**): The variety is able to limit growth and development of a specific harmful organism but it might show a larger range of symptoms or damage in comparison with high resistance varieties. Anyway intermediate resistance varieties show less damages and symptoms than susceptible varieties when cultivated in the same environmental condition and/or with the same pressure exerted by the harmful organism. It is important to observe that when a specific variety is defined “resistant”, the so-called resistance is limited at a specific biotype, patho-type, race or stump/log of the harmful organism. If a resistance is declared without specifying any biotype, patho-type, race or stump/log, that means that it does not exist any approved/recognized classification of the specific harmful organism as a biotype, patho-type, race or stump/log. If new biotypes, patho-types, races or stumps/logs occur, these are not covered by the original declared resistance/ the original resistance does not pledge also the plant resistance to them.
Immunity: when a plant is not subject to being attacked or infected by a specific parasite harmful organism.
Tolerance: the feature of a plant variety to resist abiotic stress, without serious complications regarding development, aspect and yield.
