摘　　要：Genebanks are considered the"crown jewels"of research organizations,as they safeguard valuable plant genetic resources and address the emerging challenges posed by climate-related constraints(Anglin et al.,2018).Currently,7.4 million accessions have been conserved in 1750 gene banks worldwide.Of these,only 10%are being used for crop improvement(Commission on Genetic Resources for Food and Agriculture,2010).The limited availability of passport data and the challenge of characterizing trait attributes of accessions at large scale are some of the challenges to relate their true value(Tadesse et al.,2019).Obtaining traits such as agronomic or nutritional characteristics requires extensive field phenotyping and multiple site testing over several seasons.This will create value with accurate evaluation of genotype-by-environmental variation in a given trait.The use of low-cost high-throughput phenotyping(HTP)methods to characterize the genotypic and phenotypic representations of genebank genetic resources,otherwise known as genebank phenomics,will help in understanding crops'potential for use in breeding programs with desirable traits.
