USPP28666P3 - Red raspberry plant named ‘KOKANEE’ - Google Patents

Abstract

A new and distinct red raspberry cultivar distinguished by its moderate to high yields of large, bright-red-colored, firm, conic, sweet, flavorful fruit with excellent fresh fruit quality borne on primocanes in late summer

Description

Latin name of the genus and species of the plant claimed: ‘KOKANEE’ is a new red raspberry plant that is a Rubus idaeus L.

Variety denomination: The new red raspberry plant claimed is of the variety denominated ‘KOKANEE’ containing Rubus idaeus germplasm.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct raspberry cultivar designated ‘Kokanee’ and botanically known as Rubus idaeus L.

This new raspberry cultivar was discovered in Corvallis, Oreg. in September 2009 and originated from cross of ORUS 1173-2 (unpatented) and ‘Vintage’ (U.S. Plant Pat. No. 24,198); (herein incorporated by reference in its entirety). The new cultivar is firmer and more uniformly shaped than its maternal parent, and later ripening and more conically shaped than the paternal parent. ‘Kokanee’s closest comparison cultivars are its paternal parent ‘Vintage’ (supra) and ‘Heritage’ (supra). ‘Kokanee’ is later ripening and more vigorous than ‘Vintage’ (supra) and earlier ripening and bears large and lighter colored fruit than ‘Heritage’ (supra). The new cultivar has been asexually reproduced annually since 2009 by the use of root cuttings in Corvallis Oreg. The new cultivar was established in vitro from a cane cutting and microcuttings have been rooted from this sort of culture. The new raspberry plant has been found to be stable and reproduce true to type through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Oreg.: 1. firmer and more uniformly shaped than the maternal parent ORUS 1173-2; 2. later ripening and more conically shaped than the paternal parent ‘Vintage’; and 3. moderate to high yields of large, bright-red-colored, firm, conic, sweet, flavorful fruit with excellent fresh fruit quality borne on primocanes in late summer.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs show typical specimens of the new cultivar at various stages of development as nearly true as it is possible to make in color reproductions.

FIG. 1. Shows a section of young cane showing glaucosity and sparseness of prickles.

FIG. 2. Shows the upperside and underside of the plant leaves.

FIG. 3. Shows a range of developmental stages including unopened flower buds, mature open flowers, an immature fruit, a mature fruit without the receptacle, a receptacle with the fruit removed, and a fruiting lateral with ripe fruit.

The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DETAILED DESCRIPTION OF THE NEW CULTIVAR

The following is a detailed description of the botanical and pomological characteristics of the subject raspberry ‘Kokanee’ based on observations taken from 2010 to 2015 growing seasons in trials in Corvallis and Aurora, Oreg. This description is in accordance with UPOV terminology. Color designations, color descriptions and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic and cultural conditions. ‘Kokanee’ has not been observed under all possible environmental conditions.
