Data: More than 1000 genotypes are required to derive robust relationships between yield, yield stability and physiological parameters: a computational study on wheat crop

APSIM-Wheat (www.apsim.info) was used to simulate a data set (for details, see Casadebaig et al., 2016) with 9100 virtual genotypes (N_gen= 9100) grown under 9000 environments (N_env=9000). In short, virtual genotypes were created by varying the value of 90 independent physiological parameters in a range of ±20% from the reference cultivar Hartog. Environments in the dataset contain historical climate data of 125 years (1889-2013) in four locations (Emerald, Narrabri, Yanco and Merredin) in Australia, in combination with two CO^₂ levels (380 and 555 ppm), three nitrogen levels (low: 50%, control: 100% and high fertilization: 100% plus 50 kg‧ha^-1) and three sowing dates (early, control and late).
