Rapid phenotyping of different maize varieties under drought stress by using thermal images
(2011) Müller, Joachim; Romano, Guiseppe; Zia, Shamaila; Spreer, Wolfram; Cairns, Jill; Araus, Jose Luis
The development of maize genotypes with high yields under drought is of pivotal relevance for the International Maize and Wheat Improvement Centre (CIMMYT). Thermal images of the canopy of different 92 maize genotypes were acquired in the time interval between anthesis and blister stage with each picture containing five plots of different genotypes. Mean temperature differences of more than 2°C between different genotypes under water stress were then detected using thermal images. Genotypes better adapted to drought exhibiting lower temperatures. A canopy thermal image is a potential promising method to accelerate the screening process and thereby enhance phenotyping for drought adaptation in maize.
