  1. GRP = grouping factor for checks (C1-C6), testers (nT, fT) and groups (G0-G3) of genotyped lines. Z1=1 for genotyped lines and 0 otherwise. Z2=1 for non-genotyped lines and 0 otherwise. GENA denotes all the individual genotypes. GENB=GENA for genotyped lines and 1 otherwise. GENB helps specify the vector of random effects of genotyped lines with a length that matches the dimension of the covariance matrix of genotypes.
