SMART breeding (Selection with Markers and Advanced Reproductive Technologies) or Precision breeding refers to a genetic engineering technique of reproducing a species members together to retain desirable traits and so produce a stronger hybrid. The technique was successfully used by Nachum Kedar, an Israeli scientist, who applied the technique using beefsteak tomatoes to produce a fruit that would ripen on the vine and remain firm in transit.
Smart breeding has been advanced as an alternative to transgenics as a way to produce plants that are resistant to various environmental problems.
