Fig. 10. The relative performance of the Mapping Start Only (MSO) and Mapping As You Go methods for three general classes of genetic models (E = 10; K = 0, 1, 2) for two different starting population configurations (low and high linkage disequilibrium [LD] among markers). In all cases, performance is represented as the difference in response between a given breeding strategy and the MSO method. The performance differences are expressed in terms of normalized trait value. Each line represents average performance across 1000 runs of the breeding program (24000 runs in total). A categorization of the E(NK) models considered is given in Table 1; E = the number of different environment types conditioning gene-by-environment interactions in the target population of environments, and K = level of epistasis.
