USPP26872P2 - Raspberry plant named ‘Koplinberry’ - Google Patents

Abstract

A new cultivar of Rubus idaeus, ‘Koplinberry’, characterized by its trailing plant habit with arching canes that require trellising, its ever-blooming plant habit with floricanes flowering from March to hard frost and primocanes flowering in summer in Atlanta, Ga., its rapidly maturing canes that yield edible fruit in the first season of growth, its long harvest season with non-uniform fruit ripening; lasting from April to November in northern Georgia, its fruit that are borne beneath the foliage, and its leaves that have, primarily, three leaflets and are medium green in color, and its canes that are colored medium green in the shade, red in full sun, and brown near the base.

Description

Botanical classification: Rubus idaeus.

Cultivar designation: ‘Koplinberry’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of raspberry plant, botanically known as Rubus idaeus ‘Koplinberry’ and will be referred to hereinafter by its cultivar name, ‘Koplinberry’. ‘Koplinberry’ is grown for fruit production and is particularly well suited for homeowners and garden market use in Georgia.

‘Koplinberry’ was discovered by one of the Inventors as a chance seedling in a garden in Atlanta, Ga., in 2007. ‘Koplinberry’ resulted from the open pollination of raspberry plants of unknown varieties that were growing in the Inventor's garden and the parentage is therefore unknown.

Asexual propagation of the new cultivar was first accomplished by one of the Inventors by division of rooted canes in Atlanta, Ga. in summer of 2010. Asexual propagation of the new cultivar by division of rooted canes and in vitro propagation initiated by meristem tissue has shown that the characteristics of the new cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Koplinberry’ as a new and unique cultivar of Rubus.

• • 1. ‘Koplinberry’ exhibits a trailing plant habit with arching canes that require trellising.
  • 2. ‘Koplinberry’ exhibits an ever-blooming plant habit with floricanes flowering from March to hard frost and primocanes flowering in summer in Atlanta, Ga.
  • 3. ‘Koplinberry’ exhibits rapidly maturing canes that yield edible fruit in the first season of growth.
  • 4. ‘Koplinberry’ exhibits a long harvest season, with non-uniform fruit ripening, lasting from April to November in Northern Georgia.
  • 5. ‘Koplinberry’ exhibits fruit that are borne beneath the foliage.
  • 6. ‘Koplinberry’ exhibits leaves that have primarily three leaflets
  • 7. ‘Koplinberry’ exhibits canes that are colored medium green in the shade, red in full sun, and brown near the base.

‘Koplinberry’ can be most closely compared to the limited number of raspberry cultivars recommended to Georgia gardeners; ‘Autumn Bliss’ (U.S. Plant Pat. No. 6,597), ‘Dormanred’ (not patented), ‘Polka’ (not patented), ‘Heritage’ (not patented), and ‘Redwing’ (not patented). ‘Koplinberry’ can also be compared to the raspberry cultivar ‘Prelude’ (U.S. Plant Pat. No. 11,747). ‘Autumn Bliss’ differs from ‘Koplinberry’ in having erect canes and in having short fruiting laterals. ‘Dormanred’ is similar to ‘Koplinberry’ in having a trailing plant habit. ‘Dormanred’ differs from ‘Koplinberry’ in having rounder foliage, in having flowers that are pink in color, and in having fruit that is larger in size. ‘Polka’ differs from ‘Koplinberry’ in having a very upright plant habit and in having berries that are much more elongated in shape. ‘Heritage’ differs from ‘Koplinberry’ in having an upright plant habit and in being a late season primocane producer. ‘Redwing’ differs from ‘Koplinberry’ in having leaves primarily with five leaflets. ‘Prelude’ is similar to ‘Koplinberry’ in having an early fruiting season, in producing a fall primocane crop, and in having fruit with a similar shape, numbers of drupets, and average fruit weight. ‘Prelude’ differs from ‘Koplinberry’ in having sparse spine density, in having canes that are self-supporting, in having fruits that separate from the receptacle with a smooth collar (rather than indented), and in having fruit that is openly positioned (rather than under the foliage).

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Rubus. The photographs in FIG. 1 and FIG. 2 were taken of five year-old plants as grown in the ground in Atlanta, Ga. The photograph in FIG. 3 was taken of ten-month old plants as grown from tissue culture in seven-gallon containers in Atlanta, Ga.

The photograph in FIG. 1 provides a close-up view of a fruiting branch of ‘Koplinberry’ showing berries at different stages of maturation.

The photograph in FIG. 2 provides a view of the overall plant habit of ‘Koplinberry’.

The photograph in FIG. 3 provides a view of potted plants, bearing fruit in the first year of growth, of ‘Koplinberry’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized. The colors in the photograph may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Rubus.
