Tomato breeding with a desirable MADS-box mutation to improve harvesting can often result in unwanted traits due to negative epistatis with cryptic mutations. A dosage mechanism involving a duplication of a second gene to overcoming the negative epistasis is dissected, enabling the design of gene editing strategies to predictably improve harvesting.
