a
LD environment (WI, IA, DE, MO, NC, nTX); SD environment (FL, PR); cTX was excluded due to uncertainty about LD/SD classification, but the data suggested similarity to a SD environment.
b
Values correspond to the environment-classified (LD or SD) mean±s.e. of environment-specific effects (calculated using estimates from the generation-means model: for checks: β+ςs=1+κc+κc*ee; for Tusón: β+ςs=2+γg+γg*ee).
c
No DTS data were available from MO.
d
No DTS or DTA data were available for CML254 in WI, DE or nTX.
