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.

DETAILED BOTANICAL DESCRIPTION
The plants depicted and described herein were planted in 2010 on their own roots at Bernalda-Metaponto, Matera, Italy. Photographs were taken in 2017, and observations were recorded from 2012 to 2019. This description relies primarily on the observations recorded in 2018 and 2019. Colors are described with reference to The Royal Horticultural Society Mini Colour Chart (2005).
