USPP30862P3 - Apple tree named ‘GS-66’ - Google Patents

Abstract

‘GS 66’ is a new apple tree variety notable for its fruit. Apples of ‘GS 66’ exhibit a shiny red overcolor, crisp juicy non-browning flesh, and resistance to bruising.

Description

Latin name: Malus domestica.

Variety denomination: ‘GS 66’.

BACKGROUND OF THE VARIETY

‘GS 66’ is a new and distinct variety of apple tree (Malus domestica) of unknown parentage. ‘GS 66’ originated from an open cross in 2008 in a commercial orchard at Wendhausen, Germany in 2008, and was identified by the inventor as a candidate for further evaluation in 2012. ‘GS 66’ was first asexually reproduced by table grafting at Wendhausen, Germany in 2013, and has since been observed to remain true to type over successive asexually propagated generations.

BRIEF DESCRIPTION OF THE VARIETY

‘GS 66’ was first selected for its shiny red overcolor and dominant lenticels, crisp juicy non-browning flesh, and resistance to bruising. Comparisons of ‘GS 66’ to similar varieties are shown in the following table.
