Apple tree named ‘CH 101’

Abstract

A new ‘Gala’-type apple variety named ‘CH 101.’ The new variety is distinguished by its large orange-red fruit, high fruit sugar content, and resistance to scab.

Description

Latin name: Malus domestica Borkh.

Variety denomination: ‘CH 101’.

BACKGROUND OF THE VARIETY

‘CH 101’ is a new and distinct variety of apple tree. This new variety is a product of a controlled cross made in 1992 at Wädenswil, Switzerland, of ‘Gala’ (female parent, U.S. Plant Pat. No. 3,637) and ‘K1R20A44’ (male parent, not patented), and is characterized by its large fruit, high fruit sugar content, and resistance to scab. A seedling resulting from the cross was asexually propagated by grafting in 1994 at Wädenswil, and was subsequently observed over successive asexually propagated generations. The tree and its fruit have been found to remain true to type and to retain the desirable characteristics for which the variety was selected.

BRIEF DESCRIPTION OF THE VARIETY

‘CH 101’ was first selected for its large fruit, high fruit sugar content, and resistance to scab. It is distinguished from other known Gala-type varieties by these characteristics, as well as by its orange-red over-color.

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY

The following-detailed botanical description is based on observations made during the 2008 through 2011 growing seasons at Wädenswil, Switzerland of ‘CH 101’ trees planted in 2004 on ‘J-TE-E’ rootstock (not patented).
