Abstract
The new and distinct variety of cherimoya tree, “Annona Cherimola,” is of large size, vigorous, spreading growth, and a regular and productive bearer of large-sized fruits with firm white flesh with excellent mango-like flavor and eating quality with flesh that is smooth in texture. Seeds are smaller than average for the species. Stem is smaller than average for the species, lending to a more favorable fruit ratio. In comparison with conventional commercial cherimoyas grown under the same conditions, the new variety has flesh remaining in firm condition longer under storage, with superior texture, and high soluble solids (average 23.0 Brix).
