Characterisation of 10 cherimoya (Annona cherimola Mill.) cultivars and their response to artificial pollination in Quillota, Chile.

Cherimoya cultivation in Chile occupies about 1200 hectares, producing for both the internal and export markets, principally the USA, Japan and certain Latin American countries. Chilean cultivars, such as Bronceada and Concha Lisa, possess some favourable characteristics, such as loose seeds and good postharvest storability, but also have low sugar content and are late-maturing in the principal cultivation areas, which make them less attractive. A series of new cultivars have been introduced to Chile, which are currently being studied in the Quillota Valley. Fruits from the first harvest (picked on 15 August, 15 September and 15 October) were evaluated. External characteristics such as colour, weight, shape, and skin type, together with days to harvest-ripeness, pulp resistance, pulp colour, percentage by weight of fruit components, seed characteristics, biochemical compounds, pH, soluble solids, acidity and organoleptic characters were recorded. In addition, the response of each cultivar to art

ificial pollination was evaluated. Preliminary results showed that there are new cultivars that are superior to Chilean cultivars with respect to time of harvest (thus allowing a longer harvest period). In terms of organoleptic quality, cultivars Cholan and Loma were superior to the other tested cultivars.
