A sexually and vegetatively reproducible diploid seedless watermelon inducer via ClHAP2 mutation.

Seedless watermelon production relies on triploid cultivation or the application of plant growth regulators. However, challenges such as chromosomal imbalances in triploid varieties and concerns about food safety with growth regulator application impede progress. To tackle these challenges, we developed a sexually and vegetatively reproducible inducer line of diploid seedless watermelon by disrupting the double fertilization process. This innovative approach has enabled the successful induction of diploid seedless watermelon across diverse varieties.
