Abstract

In any plant breeding programme in an area of climate change, plant phenotyping is required to produce high-yielding crops. The success of a breeding programme is dependent on the precise measurement of phenotyping traits and the ability to correlate these with gene or quantitative trait locus (QTL) expression. However, precision in phenotyping is a major obstacle because of the complexity associated with environment and genotype interaction. Plant phenotyping traits and their importance vary depending on the breeding objective. Phenotyping under abiotic stress includes a set of physiological traits that indirectly explain the stress tolerance and susceptibility of the genotype. Although a large amount of information is available on the methods of estimating these traits, there is minimum information on the significance of these traits under abiotic stress conditions. This chapter focuses on the different physiological traits available for phenotyping and their underlying principles and importance under stress conditions, and highlights the new temperature-controlled phenotyping facility.
