Abstract

‘Venice’ apple tree (Malus domestica Borkh) is a new variety selected for its low chilling requirement, resistance to Gala leaf spot disease and partial horizontal resistance to apple scab, high fruit quality, and excellent storageability.

Description

Latin name: Malus domestica Borkh.

Variety denomination: ‘Venice’.

BACKGROUND OF THE VARIETY

‘Venice’ is a new and distinct variety of apple tree (Malus domestica Borkh) obtained from a controlled cross of ‘Imperatriz’ (female parent, not patented) x ‘Baronesa’ (male parent, not patented) carried out at Caçador, Santa Catarina, Brazil in 2000. Seeds obtained from the cross were planted at Caçador, and ‘Venice’ was selected from the resulting seedlings for propagation and further observation. ‘Venice’ was first asexually propagated by grafting in 2004 at Caçador, and has since been observed to remain true to type over successive asexually propagated generations.

BRIEF DESCRIPTION OF THE VARIETY

‘Venice ’ apple tree is distinguished by its resistance to Gala leaf spot disease (Colletotrichum spp.) and partial horizontal resistance to apple scab (Venturia inaequalis), and its low chilling requirement. Fruit of ‘Venice’ is notable for its high quality, having crisp juicy flesh and a high sugar content, and its excellent storageability.

‘Venice’ is distinguished from female parent ‘Imperatriz’ by its smaller, more acidic fruit; later ripening; more intense skin color; and improved storageability.

‘Venice’ is distinguished from male parent ‘Baronesa’ by its earlier fruit maturity (10 to 15 days earlier than ‘Baronesa’); more coarse flesh texture; higher acidity; and more pronounced overcolor.

‘Venice’ is distinguished from standard ‘Fuji’, a similar variety, by its lower chilling requirement which is particularly suited to growing conditions in Brazil; partial horizontal resistance to apple scab; lower tendency to biannual bearing; production of fruit predominantly on spur buds, as compared to ‘Fuji’, which produces fruit primarily on terminal buds of long shoots; more complete and intense overcolor on fruit; more coarse fruit texture; improved storageability; and increased susceptibility to penicilium fruit rot (Penicilium espancium) during storage.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs of the ‘Venice’ variety were taken from 2013 to 2015 at Caçador, Brazil.
