Parthenocarpic watermelon plants

A watermelon plant or plant part comprising at least one copy of a mutant allele of a gene named Watermelon Parthenocarpy gene on chromosome 7 (WAP7.1), wherein said mutant allele encodes a mutant protein comprising at least 213 amino acids deleted at the C-terminal end of the protein compared to the wild type protein,

• wherein said mutant allele confers facultative parthenocarpy when the mutant allele is in homozygous form, and wherein the wild type WAP7.1 allele encodes a wild type protein of SEQ ID NO:
• 1 or a wild type protein comprising at least 94% sequence identity to SEQ ID NO:
• 1.
