Ultra-small watermelons, weighing 80 to 200 grams, were developed by a mother and daughter using a non-GMO technique to facilitate cultivation in greenhouses, vertical farms, and individual fruit markets.

Watermelons the size of chicken eggs were obtained by a pair of breeders who used non-GMO chemical mutation to reduce the fruits without removing core characteristics, such as sweet flavor, red, orange flesh, and firmness for handling.

The proposal arose to tackle an old limitation of the crop. Watermelons have always been difficult in vertical farming systems and greenhouses due to the extensive vine growth and large fruit size.

The breeding program was initiated in 2021 by high school researcher Delaney Raptis and her mother. The goal was to create ultra-small fruits, capable of better adapting to high-density environments.

The focus of the work was to make it possible to cultivate watermelon in high-density greenhouses and vertical farms, where maximizing production per square meter is a priority for the system.

In addition to facilitating this type of cultivation, the smaller size of the fruits can reduce food waste. The miniature watermelons can also cater to the single-serving fruit market, as they are small and individual.

The breeders observed that the seeds of these watermelons are smaller than those found in normal-sized fruits. A question remains about the rind: whether it is edible or needs to be removed.
