Global Crop Diversity Trust

A Foundation for Food Security

Evaluation

In order for the crop diversity held in genebanks to be of use to breeders, and hence farmers, it must first be screened to identify traits such as resistance to pests and disease, and tolerance to heat or cold. Material with these traits can then be included in appropriate introduction and crop improvement programmes. The more accessions screened, and the more uniform the standards for documenting of these data across collections, the greater the chance of identifying promising accessions, and using then effectively in crop improvement.

The Trust has provided competitive grants to screen collections for the characteristics with the greatest potential for crop improvement, targeting traits of importance to the poor, in particular in the context of climate change. Both the material evaluated and the data generated are publicly accessible. You can download the documents below to review the results of the award scheme,  or click on the link below to search the technical results and outputs of the projects. 

Standards for recording the results of screening accessions are lacking for some important crops, and are outdated for others. The Trust has worked with Bioversity International to update or establish characterization and evaluation standards for major crops.
