A recent Washington Post article by Adrian Higgins, titled, “Trait by trait, plant scientists swiftly weed out bad seeds through marker-assisted breeding” (April 16, 2014) overstates the potential of marker-assisted selection (a molecular plant breeding method) and makes the dubious claim that it’s the most promising plant breeding method available today.
We agree that marker-assisted selection (MAS) has a role in crop improvement and has helped breeders for a quarter century understand the relationship between genes and plant traits. It is good basic research. But MAS is just one tool in a plant breeder’s toolbox, with clear limitations, which the article largely dismissed.
If the past century of agriculture has taught us anything, it’s that there are no silver-bullet solutions to complex problems, MAS included. The danger with this centralized, one-size-fits-all breeding approach is that it results in diminishing crop diversity, as well as the diversity of breeders representing different interests in creatively solving agricultural challenges at the regional level.
