I think aussies need to get some elite US cherimoyas to improve public opinion and make them popular.I think only very poor quality ones have made it here.Between 20 and 30 years ago some of the cherimoya varieties tried here are as follows:
Cherimoya varieties: Bays, Booth, Burton's Wonder, Chaffey, Kaitaia Special, Loma, Pierce, Pink, Reretai, Sabor, White.
They embarrassed themselves and made a mockery of their kind when compared to atemoyas like Pinks' Mammoth at the time.Now it has been forgotten and this place is ready for them again but they have to be good ones to start with.The same could be true in reverse with the US ripe for true mammoths,KJ's,tropic suns and maroochy golds.I would love to see a true no holds barred tussle between the champ atemoyas and cherimoyas.
By the way not all sugar apples are extra seedy. Some have numerous unseeded segments and only small seeds so it amounts to a respectable flesh yield.A 5lb mammoth can at times have only 4 or 5 seeds and so flesh yield in some atemoya is one of their strong points.
