Abstract

The rosy apple aphid Dysaphis plantaginea Passerini (Hemiptera: Aphididae) is a key pest of apple.
Resistance to this aphid has been phenotypically determined in Malus floribunda 821, and in some descendants such as Florina. Recently, a major resistance gene, Dp-fl has been mapped on the bottom part of the LG8 in the cultivar Florina. The marker CH01h10 is closely linked to Florina rosy apple aphid resistance.
The objective of this study was to evaluate the efficiency of this marker by comparison between phenotypical evaluations and marker segregation in two apple crossings, which include two local cultivars and the resistant Florina. In both crossings, Raxao x Florina and De la Riega x Florina, the frequency of tolerant versus susceptible was not different from 1:1, which confirmed that the resistance of Florina to the rosy apple aphid is determined by a single gene (Dp-fl). In both cases, there was also a strong relationship between the phenotypical and the genetic evaluation.
This study confirmed the efficiency of the molecular marker CH01h10 for the detection of the resistance to the rosy apple aphid.
