In some cooler regions of Central America and Mexico, the plant is naturalized and the fruit is common in several locales. In the United States, the plant produces well along small sections of the Southern California coast where commercial production has begun.

, smooth skin, round shape, good Havor, juiciness, low seed ratio, resistance to bruising, and good storage qualities. With these attributes, larger future production and expanded trade seem inevitable.

HORTICULTURE Because seedling trees usually bear fruits of varying quality, most commercial cherimoyas are propagated by budding or grafting clonal stock onto vigorous rootstock. However, a few forms come true from seed, and in some areas seed propagation is used exclusively.

Pollination is perhaps the cherimoya's biggest technical difficulty. Not only are reliable pollinators missing in some locations, but low humidity, especially when combined with high temperatures, causes pollination failure; these conditions dry out the sticky stigmas, and the heavy pollen falls off before it can germinate.

Currently few, if any, specific insects have been definitely associated with cherimoya pollination.7 The insects that now pollinate it in South America should be identified. Spain, where good natural fruit set is common in most orchards, might also teach much.8 Selecting genotypes that naturally produce symmetrical, full-sized fruits may reduce or eliminate the need to hand pollinate, bringing the cherimo.ya a giant step forward in several countries.

that have valuable commercial and agronomic traits. Handling Improved techniques for handling, shipping, and storing delicate fruits would go a long way to helping the cherimoya fulfill its potential.

Seedling progeny are extremely variable, and possibilities for further variety improvement are very good. So far, however, little work has been done to select and propagate superior varieties.

Its creamy white flesh is sweet but is sometimes granular and is generally considered inferior to the other commonly cultivated annonas. However, this plant is the most vigorous of all, and types that produce seedless fruits are known.

This species is closely related to cherimoya and is known from only three localities in Veracruz, Mexico, where it occurs at near sea level. Its traits would probably complement cherimoya's if the two species were hybridized to create a new, man-made fruit.
