Variétés et systèmes de culture de tomate : les apports conjoints de la génétique et de l'agronomie

Abstract : Tomatoes are produced in various conditions, ranging from the open field (mainly for processing tomatoes) to soilless greenhouses. This adaptation of cropping systems and the technological innovations that have accompanied it largely drove the evolution of varieties in recent decades. Varieties were acclimated to protected cultivation throughout the year. Varietal resistances to specific pests, adapted to the different conditions, were introduced from wild related species. In addition, varietal diversification for different markets, focusing on fruit size and shape, has emerged as a new breeding objective. However progress has been more limited for complex traits related to fruit quality or adaptation to abiotic stress. Yields and input efficiencies have also benefited from advances in agronomic sciences: nutrient recycling in soilless cultivation, fine tuning of the greenhouse climate or introduction of efficient biological control methods have characterized the recent evolution of cropping systems. A more thorough understanding of genotype x environment interactions, which is of importance for plant resilience against stresses, and a better control of fruit flavour and nutritional quality, are major challenges for the scientific community. Rapid changes in plant breeding methods, the description of the tomato genome and enhanced capacities for crop modelling foreshadow major developments in tomato varieties and cropping systems in the near future
