ABSTRACT
This chapter reviews the current state of understanding of crop stress phenotyping and describes how recent progress in high-throughput plant phenotyping can aid in identifying stress-tolerant species or genotypes. To understand the impact of stresses on plants, stress phenotyping experiments are typically performed on plants grown under controlled environment conditions or in greenhouses, where plants can be exposed to different concentrations/levels/durations of specific stresses. To date, the majority of phenotyping studies related to crop stress response have been conducted under controlled laboratory environment conditions. However, the environmental conditions in the field are much more divergent than the laboratory conditions, and therefore, the knowledge generated from the laboratory-based studies is not always applicable to the field settings, so field-level screening can be particularly valuable. For statistical analysis, 15 plants (biological replicates) were sampled randomly for each of the 104 genotypes of Brassica for each of the saline and control (non-saline) treatments.
