  • MA1, MA2, and MA3 are the approximated models based on polynomials of first, second, and third degree, respectively, for the target QTL effect. Situation S3 (see Table 1) is considered. The results are compared to the best single-environment model (ME3, for data from the environment 3 where the effect of the target QTL is the largest one).
