Kiwi plant named ‘AC 497 076’

Abstract

A new female kiwi plant named ‘AC 497 076’, distinguished by its oblong fruit with brown hairless skin and dark yellow flesh. The fruit is very sweet with low acidity, and matures relatively early.

Description

Genus and species: Actinidia chinensis Planch.

Variety denomination: ‘AC 497 076’.

BACKGROUND AND SUMMARY OF THE NEW VARIETY

The invention relates to a new variety of kiwi plant (Actinidia chinensis Planch.) named ‘AC 497 076’, which originated in the course of a plant breeding program at Udine, Italy. Female parent ‘Jintao’ (not patented) was crossed with male parent ‘A134.41’ (not patented), and ‘AC 497 076’ was selected from the resulting seedlings. The new variety has been asexually reproduced by grafting and by in vitro propagation at Bernalda-Metaponto, Matera, Italy, and has been found to remain true-to-type over successive generations.

‘AC 497 076’ is distinguished from parent ‘Jintao’ and similar variety ‘Soreli’ (U.S. Plant Pat. No. 21,552) by the characteristics set forth in Table 1 below.
