DROPS data set

Description

This dataset comes from the European Union project DROPS (DROught-tolerant yielding PlantS). A panel of 256 maize hybrids was grown with two water regimes (irrigated or rainfed), in seven fields in 2012 and 2013, respectively, spread along a climatic transect from western to eastern Europe, plus one site in Chile in 2013. This resulted in 28 experiments defined as the combination of one year, one site and one water regime, with two and three repetitions for rainfed and irrigated treatments, respectively. A detailed environmental characterisation was carried out, with hourly records of micrometeorological data and soil water status, and associated with precise measurement of phenology. Grain yield and its components were measured at the end of the experiment.
10 experiments have been selected from the full data set, two for each of the five main environmental scenarios that were identified in the data. The scenarios have been added to the data as well as a classification of the genotypes in four genetic groups.

The data.frame contains the raw phenotypic data per experiment (Location × year × water regime), one value per individual plot and outliers have been removed.

A data.frame with 6499 rows and 25 columns.
