Research topics

Stimulating plant defenses in commercial orchards or breeding new resistant apple and pear varieties are operational disease and pest control methods for which we develop upstream research programs. We especially focus on the genetic and molecular determinants of apple and pear resistance to scab (Venturia inaequalis and Venturia pirina), fire blight (Erwinia amylovora), rosy apple aphid (Dysaphis plantaginea) and psylla (Cacopsylla pyri). Integrated defense responses, from perception to induced defenses as well as constitutive defenses are investigated. Durability of resistance factors against V. inaequalis is explored in collaboration with the team EcoFun, taking into account the pathogen variability and its potential evolution. In collaboration with the team QualiPom, genetic diversity of disease resistance and other major traits are explored in germplasm collection, together with the implementation of marker-assisted selection and genomic selection.

Four main interconnected projects are conducted in a continuum of upstream/applied researches:

Genetic architecture of apple and pear resistance to diseases and pests

In apple, we seek to characterize the genetic architecture of scab resistance towards the diversity of Venturia inaequalis fungus in order to reason...

Functional genomics of apple and pear genetic and induced (PRI) disease and pest resistance

We seek to identify defence mechanisms effectively involved in pest and disease resistance, especially those involved downstream of scab and fire...

Developing plant resistance inducers (PRI)-based protection methods and use in crop management processes

For several years, we have been studying resistance induced by PRI particularly in apple. Methods for evaluating efficiency of these products were...

Contribution to the breeding of disease resistant fruit varieties

One of the main breeding objectives in apple and pear is disease and pest durable resistance. Our research activities take place upstream to breeding...
