Obtaining tomato plants with firm and intact fruit is one of the main goals in tomato breeding programs. Achieving these goals through conventional breeding is time-consuming and can lead to the loss of unwanted traits. In other hand, consumers are concerned about the presence of transgenic elements in plants acquired through RNA interference. The use of CRISPR/Cas9 technology has made it possible to overcome the above-mentioned shortcomings. In this study, the {beta}-D-N-acetylhexosaminidase ({beta}-hex) gene, which is involved in tomato fruit ripening, was knocked out using CRISPR/Cas9. In the resulting mutant plant genome, an indel mutation was found in exons 1 and 2 of the {beta}-hex gene. Plants with a mutation in their genome were observed to have increased fruit firmness and shelf life compared to control plants without affecting fruit quality.
