#' Preferred bread wheat varieties
#'
#' Data from decentralized on-farm trials of bread wheat 
#' (\emph{Triticum aestivum} L.) varieties in Vaishali, India over the 
#' 2014's Rabi season. Farmers were asked to test three varieties 
#' of bread wheat randomly assigned as incomplete blocks of 
#' three varieties (out of 16 varieties) and assess which one had
#' the best and worst performance considering 
#' four traits, germination, grain quality, yield and overall performance.
