Résumé
For many crops, the genomics revolution has given hope that breedingBreeding would become easier, faster, and more efficient. Relevant phenotyping is now the main bottleneckBottleneck and new technologies provide opportunities for easier, faster, more sensitive, and more informative phenotyping. However, the phenotyping agenda must be driven by scientific questions rather than by a technological push, especially for complex constraints, such as drought. In this chapter, we provide a viewpoint on phenotyping and what it should take into account. Phenotyping is a full-fledge research effort, calling for a multidisciplinary effort between technology providers and several research disciplines, and which needs to address the issue of linking scales. Two phenotyping platforms are described; a lysimetric platformLysimetric platform (LysiField) to assess the patterns of plant water use and relate these to grain yield,Grain yield and an imaging platform (LeasyScan) to characterize crop canopy traits responsible for water savings. In both cases, the chapter discusses the thought process and the hypotheses around key traits for drought adaptation that were put in the development of these platforms. The chapter concludes with perspectives on the integrationIntegration of high-throughput phenotypingHigh-Throughput Phenotyping (HTP) (HTP) technology with breedingBreeding, starting with an analysis of the cost as a prerequisite to decide on its usage and adoption in breeding.Breeding It takes a few examples of current opportunities in the domain of imaging, trying to bring closer together what the technology can bring and what breedingBreeding pragmatically needs. In conclusion, while new technologies provide opportunities to make phenotyping easier, faster, better, cheaper, the risk of becoming the end that justifies the means can be avoided by driving the technology with research questions, made possible through a cross-discipline approach between genetics, breeding,Breeding modeling, engineering, physiology, and statistics.
