Operations and phenotyping

Phenotyping for abiotic stress tolerance in maize: drought stress. A field manual

Crop breeding programs using conventional and/or molecular breeding approaches rely heavily on high-quality phenotypic data generated by evaluating genotypes in different environmental conditions, such as drought.

In this manual, the traits of interest for phenotyping are those that mitigate yield losses rather than those involved in the survival or escape of plants exposed to drought stress.

This manual is targeted at maize breeders and field technicians in tropical environments who are working on improving maize tolerance to drought stress.

Phenotyping for abiotic stress tolerance in maize: waterlogging stress. A field manual

Maize crops grown during the summer rainy season in the tropics occasionally face extreme weather conditions that limit crop establishment and yield potential. Among various abiotic stresses, contingent/intermittent soil waterlogging is one of the important constraints for maize production in the Asian tropics and many other maize growing areas around the world.

Operations and phenotyping

As of 2022, this work is delivered primarily through CGIAR Initiative on Breeding Resources, Work Packages 3 and 5.


New mechanization, automation, precision and high-throughput phenotyping tools have the potential to lower the cost of assessing variety traits and genotype-environment-management interactions, while improving accuracy and precision.

The operations and phenotyping module supports Platform members to adopt these new tools to increase the quantity and quality of phenotypic data they produce, and to use this data to improve the effectiveness of their breeding programs.

As a community of practice, the module creates information about tools, guides and best practices to be shared through the platform Toolbox. Expert interdisciplinary advice is shared to enable more rapid and effective adoption of phenotyping tools.

Finally, the module supports users to upgrade and share their phenotyping infrastructure, acts as a broker for approved services, and interfaces with the Bioinformatics module to support the management and use of phenotypic data.
