How do you pronounce Apricot? If it's APPricot then I suppose it's no worse than Apple and better than Banana, but in British English the first syllable sounds like Ape (non-human primate) which is not encouraging.
Plum is too tempting. Can't you just hear the playground chants? 'Plum, Plum, stinky bum' would be quite mild.
Peach really sounds unattractive.
May I suggest
Melba?
