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.

Field Book

Field Book was created to replace paper field books to enable increased collection speed with greater data integrity, using a novel collection system that only displays a single cell to be collected at a time.

Field Book can collect data in the following formats: numeric, percentage, categorical, date, Boolean, text, photo, counter, rust rating, and audio. Traits are defined by the user and can be exported and transferred between devices. Sample files are provided with the installation.


The KDSmart application, designed for Android handheld devices, enables data collection in the field. Trial/Nursery phenotypic data, selectively imported into KDSmart, is available in the field for efficient and reliable data capture and storage ready for upload.

KDSmart can be used:
