Bioscience in brief
Plant genetics and crop breeding
How do you develop a new crop variety by marker-assisted selection (MAS)?
Markers allow detection of genetic variation at a known location, which can be either the gene of interest, or a location nearby.
Markers are used as a way of indirectly selecting the plant trait of interest.
The breeder won’t have to wait until the next generation is fully grown to select plants carrying the desired traits. The next generation can be screened for the trait at any time.
