Stay green Cucurbitaceae plant

A Cucurbitaceae plant comprising a mutated stay green gene in homozygous form, wherein said stay green gene encodes for a protein having at least 87% sequence identity with SEQ ID NO:

• 2 or SEQ ID NO:
• 6, and wherein the mutated stay green gene comprises at least one mutation in the stay green gene resulting in an amino acid substitution of Serine(S) to Phenylalanine (F) or Leucine (L) at amino acid position 52 or position 54 (S52F, S52L, S54F or S54L), and/or an amino acid substitution of Arginine (R) to Lysine (K) at amino acid position 72 or 74 (R72K or R74K) in the protein sequence of SEQ ID NO:
• 2 or SEQ ID NO:
• 6, respectively, and wherein said plant produces fruit with an increased shelf life compared to a wild type control plant.
