This dataset belongs to the USDA Northern Region Uniform Soybean Tests,
and it is a subset of the data used by Krause et al. (2023). It contains the
empirical best linear unbiased estimates of genotypic means of the seed yield
from 39 experimental genotypes evaluated in 14 locations. The original data, available at the package
SoyURT, has 4,257 experimental genotypes evaluated at 63 locations and
31 years resulting in 591 location-year combinations (environments) with
39,006 yield values.
