The “Mapping As You Go” (MAYG) approach continuously re-estimates QTL effects as breeding populations evolve, accounting for epistasis and genotype-by-environment interactions. By updating marker information across breeding cycles, breeders can maintain more accurate and biologically relevant selection decisions.

Each method—from simple single-marker tests to multi-QTL models—represents a step forward in power, resolution, and biological insight. Here is a practical overview for everyone who want to understand how these methods work and what each can (and cannot) do.
