Multigenic resistance
A lexical equivalent of polygenic, albeit not an ideal alternative due to its heterogenous etymological derivation. This term denotes the presence of multiple genes that influence a particular trait or phenotype. However, its linguistic roots originate from a varied set of sources, rendering it less than optimal in certain scientific contexts. Nonetheless, its use is…
-
Monogenic resistance
The regulation of resistance by a single (or multiple) genes is a phenomenon known as monogenic resistance. In contrast, resistance governed by a small number of genes is designated as oligogenic resistance.
-
Minor gene resistance
The expression of resistance is determined by genetic factors that manifest through minute impacts. It is crucial to note that this type of resistance cannot be equated with polygenic resistance.
-
Mature tissue resistance
Resistance can manifest itself during any stage of host growth and is a product of tissue maturity.
-
Major gene resistance
The regulation of resistance by genes is subject to the influence of genes that possess a notable degree of potency. It is important to note that this type of resistance is distinct from oligogenic resistance. When it comes to classifying genes as major or minor determinants, this categorization is highly arbitrary and hinges upon subjective…

Juvenile resistance
Upon initial stages of host development, evidence of resistance has been identified.
-
Horizontal resistance
Resistance that spreads uniformly against all pathogen races has been studied and documented in J.E. van der Plank’s book “Plant Diseases: Epidemics and Control” published in 1963 by Academic Press in New York and London. Another form of resistance, known as vertical resistance, refers to the absence of differential interactions when subjected to an analysis…

General resistance
Resistance to multiple diseases is a phenomenon that can also be referred to as non-race specific resistance, although experts do not recommend using the two terms interchangeably.
-
Resistance field
The resistance that is noticeable in natural infections under field conditions is not discernible during the controlled experimental conditions of resistance tests. This type of resistance is expressed when the inoculum potential is low and is highly sensitive to environmental factors. Horizontal resistance typically falls under this category, but it’s important to note that…

Adult plant resistance
After the developmental stage of post-seedling, there has been an observation of resistance. However, there is no clear indication of its mode of inheritance or specificity. It is synonymous with the resistance observed in mature plants.
