The deltabreedquery R package provides tools to retrieve data from DeltaBreed, Breeding Insight’s breeding data management platform, using the open-source BrAPI standard.
Using deltabreedquery, you can import all of a program’s experiments, germplasm, trait definitions, and observation (phenotype) data directly into R, without the need to reformat or manually download + read in files.
Observation data can be filtered on a range of common fields: year, location, trial type, etc.
Start here
To try out the basic functions, install the package from CRAN on any R environment and load an example program:
install.packages("deltabreedquery")
library(deltabreedquery)
login_deltabreed("example")
expts <- get_experiments()
germ <- get_germplasm()
obs <- get_observations()
filt <- filter_observations(location = "Manitoba", year = 2026)Learn more
For more detailed instructions on using deltabreedquery with a live instance of DeltaBreed, please see the GitHub README.
For a full list of functions, please see the package’s reference manual on CRAN.
