Abstract

A sweet cherry tree named ‘Denfer’ distinguished by its regular production of firm uniform fruit with good acid to sugar balance.

Description

Latin name: Prunus avium.

Variety denomination: ‘Denfer’.

BACKGROUND AND SUMMARY OF THE VARIETY

The new sweet cherry tree named ‘Denfer’ originated as a seedling obtained from a controlled cross of ‘Agoudel’ (female parent, not patented) with ‘Burlat’ (male parent, not patented) carried out at Bordeaux, France in 1994. The seedling was first asexually propagated by grafting at Bordeaux, France in 2001 and subsequently observed over several growing seasons. The ‘Denfer’ sweet cherry tree was initially selected for its regular production of firm uniform fruit with good acid to sugar balance.

‘Denfer’ is distinguished from its parents and similar variety ‘Folfer’ (not patented) as set forth in Tables 1 through 3 below.

TABLE 2

Comparison of ‘Denfer’ to male parent ‘Burlat’

Characteristic	‘Denfer’	‘Burlat’

Time of beginning of fruit	Mid to late June (15 to 18	Early

The ‘Denfer’ sweet cherry tree has been found to retain its distinctive characteristics through successive asexually propagated generations.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs were obtained in 2022 at Parker, Washington. The tree shown was planted in 2015.

FIG. 1 shows ‘Denfer’ cherries and leaves on the tree; and

FIG. 2 shows ‘Denfer’ cherries.

The colors shown in the photographs may vary with lighting conditions. Color characteristics of the claimed plant should therefore be determined with reference to the observations described herein, rather than from the photographs alone.

DETAILED BOTANICAL DESCRIPTION

The following detailed botanical description is based on observations of ‘Denfer’ cherry trees growing on Maxma® 14 rootstock (not patented). The described trees were planted in 2015 at Parker, Washington. Observations were recorded during the 2022 growing season. The characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and will vary with location and season.
