Research and/or project statements

My research program is aligned with AAFC sector strategies to increase agricultural productivity, and reduce threats to the value chain. Aphanomyces root rot is an increasing threat to pulse production in Alberta and Saskatchewan. New techniques, based on molecular pathogen quantification in soils, combined with integrated crop management practices to reduce losses in peas and lentils due to root rots are being developed. Foliar diseases, such as white mould and bacterial blights, also continue to reduce the yield potential of pulse crops. By screening breeding lines for disease reactions in the greenhouse and disease nurseries, breeders can improve productivity by incorporating improved resistance into elite cultivars thus reducing the impact of biotic stresses.  

Professional activities / interests

Mon programme de recherche concorde avec les stratégies sectorielles d’Agriculture et Agroalimentaire Canada (AAC) qui visent à améliorer le rendement agricole et à réduire les menaces qui guettent la chaîne de valeur. La nécrose racinaire précoce du pois, causée par le champignon Aphanomyces, représente un risque croissant pour la production de légumineuses à grains en Alberta et en Saskatchewan. Nous travaillons à la mise au point de nouvelles techniques basées sur la quantification moléculaire des pathogènes présents dans le sol combinées à des pratiques intégrées de gestion des cultures afin de prévenir les pertes associées à la nécrose des racines dans les cultures de pois et de lentilles. Les maladies foliaires, comme la pourriture à sclérotes et la graisse bactérienne, inhibent toujours le potentiel de rendement des légumineuses à grains. En examinant la réaction aux maladies des lignées généalogiques présentes dans les serres et les pépinières de recherche, les sélectionneurs peuvent améliorer la productivité en insérant des gènes de résistance accrue dans les cultivars d’élite, réduisant du même coup l’impact des stress biotiques.
