Their flavour is excellent but their storage life is relatively short. CluthaSun' 'CluthaSun', like all the remaining selections from the 'Clutha' series, is a cross between the varieties 'Moorpark' and 'Sundrop'. Its fruit ripen 3-4 days after 'Sundrop'. Its trees are vigorous and relatively free of stonefruit blast, but not necessarily free of bacterial spot, Xanthomonas campestris pv. In storage trials, 'Cluthasun' stored well for at least 4 weeks.
Fruit are also suitable for canning and drying.
The trees set heavy crops and the flowers are self-compatible. CluthaGem' 'CluthaGem' has performed well in Blenheim, while in Central Otago the fruit have been rather small. A characteristic of this selection is its ability to consistently set heavy crops, despite the fact that its flowers are self-incompatible. In Central Otago it has a tendency to overset. A pollenizer that flowers at the same time as 'CluthaGem', such as 'Sundrop' or 'CluthaGold', will be a necessary part of any planting of this selection.
