Genetic analysis of resistance to apple scab (Venturia inaequalis) in apple (Malus x domestica Borkh)

Abstract

Amongst the many problems facing the apple industry, apple scab is one of the most challenging experienced by producers. This disease is caused by Venturia inaequalis, which causes lesions to develop on both the fruit and leaves. The fungus is usually controlled by extensive use of sprays, but molecular genetics have made more environmentally friendly techniques available. This study was aimed at constructing a genetic linkage map from apple, which would be used in marker-assisted selection (MAS).
