Selection schemes have remained relatively the same for a long time. Here, too, the most significant change over the last half century has been driven by molecular technology. The use of molecular markers in selection (MAS) gained significant attention over the period. Most traits of interest to breeders are quantitatively inherited. The continuing challenge with this approach is the lack of precision (need for more high‐resolution QTL maps) and higher throughput marker technology, among others. Selected genotypes are evaluated across time and space in the same old fashioned way.
