Multi-environment trial of maize hybrids in China
Yield of 13 hybrids, grown in 10 locations across 2 years. Conducted in Yunnan, China.
A data frame with 260 observations on the following 5 variables.
gengenotype
maturitymaturity, days
yearyear
loclocation
yieldyield, Mg/ha
Data are the mean of 3 reps.
These data were used to conduct a stability analysis of yield.
