Steven Tanksley and the Tomato Code – The Pioneer of DNA Markers
In the late 1980s, Steven Tanksley transformed plant breeding by bringing DNA into the field. His pioneering work at Cornell produced the first comprehensive marker map of the tomato genome, laying the foundation for marker-assisted selection—now a cornerstone of modern, non-GMO breeding. From fruit shape to disease resistance, Tanksley’s breakthroughs turned invisible genetic information into practical tools used by breeders worldwide. And remarkably, it all began with a tomato.
