Non-transgenic approaches refer to methods of developing new plant varieties without inserting foreign DNA from other species, relying instead on techniques like traditional breeding, marker-assisted selection, or gene editing that modifies existing genes in place. This distinction matters greatly in plant science because non-transgenic crops often face fewer regulatory hurdles and greater consumer acceptance compared to conventional genetically modified organisms. As a result, researchers increasingly favor these strategies to improve traits such as disease resistance, yield, or fruit quality while avoiding the controversies associated with introducing genes from unrelated organisms.
Scientists used a precise gene-editing tool to make watermelon naturally resistant to glyphosate herbicide, without introducing foreign DNA. The resulting plants tolerate real-world herbicide doses and can be used as breeding parents to pass this trait to new varieties.

Prime editing of the watermelon EPSPS gene conferred glyphosate resistance without inserting foreign DNA

Heterozygous mutant plants tolerated field-level herbicide doses with no measurable growth penalty

Visible markers in the editing platform allow breeders to identify and select edited plants for use as parental lines
