USPP32742P3 - Kiwi plant named ‘AC 501 022’ - Google Patents

Abstract

A new female kiwi plant named ‘AC 501 022’, distinguished by its oblong fruit with dark brown hairless skin and yellow flesh. The fruit is very sweet with low acidity, and matures relatively early.

Description

Genus and species: Actinidia chinensis Planch.

Variety denomination: ‘AC 501 022’.

BACKGROUND AND SUMMARY OF THE NEW VARIETY

The invention relates to a new variety of kiwi plant (Actinidia chinensis Planch.) named ‘AC 501 022’, which originated in the course of a plant breeding program at Udine, Italy. Female parent ‘Ac328.26’ (not patented) was crossed with male parent ‘A134.41’ (not patented), and ‘AC 501 022’ 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 501 022’ is distinguished from parent variety ‘Ac328.26’ and similar variety ‘Soreli’ (U.S. Plant Pat. No. 21,552) by the characteristics set forth in Table 1 below.
