Horizontal resistance

Last updated

In genetics, the term horizontal resistance was first used by J. E. Vanderplank [1] to describe many-gene resistance, which is sometimes also called generalized resistance. [2] This contrasts with the term vertical resistance which was used to describe single-gene resistance. Raoul A. Robinson [3] further refined the definition of horizontal resistance. Unlike vertical resistance and parasitic ability, horizontal resistance and horizontal parasitic ability are entirely independent of each other in genetic terms.[ citation needed ]

Successive rounds of breeding for horizontal resistance proceed in a more traditional fashion, selecting plants for disease resistance as measured by yield. These plants are exposed to native regional pathogens, and given minimal assistance in fighting them. [4]
