Heritability based on variance among random S0:1 families from two different populations evaluated in a common multi-environment trial, with missing data.
Data are taken from Cervantes-Martinez et al. (2002) Crop Sci: In Press.
Briefly: yield was measured on 20 random S0:1 lines within five sets for each of two populations across four environments in
To perform the analysis you first need to download the data files :
Original data on a plot basis for all lines (including checks) is available in an Excel spreadsheet file . To use the SAS code given, this spreadsheet must be open when running the SAS program!
