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.
gen
genotype
maturity
maturity, days
year
year
loc
location
yield
yield, Mg/ha
Data are the mean of 3 reps.
These data were used to conduct a stability analysis of yield.
