Abstract
This invention relates to a new and distinct everbearing variety of raspberry plant named ‘PS-10.028-58’. The new variety is primarily adapted to the growing conditions of the central coast of California and is characterized by the following: mid-season primocane production with medium sized fruit of light-red coloration. Fruit is of consistent conic shape, releases easily from receptacle, is glossy and possesses very good flavor. Foliage is slightly convex, medium green; possessing medium rugosity, weak gloss and equal 3-5 foliates. Primocanes have an absent or very weak waxy coat, medium thorn density of small purple spines and have very weak anthocyanin coloration.
Description

Latin name of the genus and species of the plant claimed: Rubus idaeus.


Variety denomination: ‘PS-10.028-58’.


CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to and the benefit of U.S. Provisional Application No. 62/430,475 filed Dec. 6, 2016, the entire disclosure of which is incorporated by reference herein.


BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct fall bearing raspberry variety designated as ‘PS-10.028-58’. This new variety is a result of a controlled cross made in 2010 in Watsonville, Calif. between raspberry variety ‘GRANDEUR’ (patented, U.S. Plant Pat. No. 20,459) as the female parent and raspberry variety ‘04.3891’ (unpatented) as the male parent in an ongoing breeding program. The variety is botanically known as Rubus idaeus.


The seedling resulting from the aforementioned cross was asexually propagated by dormant canes in Santa Cruz County, Calif. and was subsequently selected by the inventor from a controlled breeding plot in Watsonville, Calif. in 2012. After its selection, the new variety was further asexually propagated by dormant canes, roots and non-dormant root shoot cuttings in Santa Cruz County, Calif., San Joaquin County, Calif. and Siskiyou County, Calif. The new variety was then extensively tested over the next several years in fruiting fields in Santa Cruz County, Calif. This propagation has demonstrated that the combination of traits disclosed herein as characterizing the new variety are fixed and remain true to type through successive generations of asexual reproduction.


BRIEF SUMMARY OF THE INVENTION

‘PS-10.028-58’ is primarily adapted to the climate and growing conditions of the central coast of California. This region provides the necessary year-round temperatures required for it to produce and maintain a strong vigorous plant and to remain in fruit production from July through December on primocanes and in the ensuing year from May through July on floricanes. The following traits have been repeatedly observed and are determined to be unique characteristics of ‘PS-10.028-58’, which in combination distinguish this raspberry plant as a new and distinct variety:

    • 1. Dark purple spines
    • 2. High fruit yield
    • 3. Light to medium red fruit color
    • 4. Absent to very weak primocane glaucosity
    • 5. Very good flavor


The raspberry variety that is believed to be most closely related to the new raspberry variety ‘PS-10.028-58’ is the raspberry variety ‘GRANDEUR’ (patented, U.S. Plant Pat. No. 20,459). In comparison to the similar raspberry variety ‘GRANDEUR’, ‘PS-10.028-58’ differs by the following combination of characteristics described in Table 1:

BRIEF DESCRIPTIONS OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance of typical specimens of the new raspberry variety, ‘PS-10.028-58’ at various stages of development as true as reasonably possible with color reproductions of this type. Color in the photographs may differ slightly from the color value cited in the detailed botanical description which accurately describes the color of ‘PS-10.028-58’. The depicted plant and plant parts of the new raspberry variety ‘PS-10.028-58’ were taken in Watsonville, Calif. and are approximately 2 to 16 months old:



FIG. 1 shows typical primocane foliage and fruit color; foliate and rugosity characteristics of ‘PS-10.028-58’ taken in the month of May 2015;



FIG. 2 shows typical gloss, coloration, and drupelet formation of floricane fruit of ‘PS-10.028-58’ taken in the month of May 2015;



FIG. 3 shows typical harvested fruit of ‘PS-10.028-58’ taken in the month of July 2015;



FIG. 4 shows typical dormant cane color characteristics of ‘PS-10.028-58’ taken in the month of January 2013.





DETAILED BOTANICAL DESCRIPTION

‘PS-10.028-58’ has not been observed under all possible environmental conditions. The characteristics of the new variety may vary in detail, depending upon variations in environmental factors, including weather (temperature, humidity and light intensity), day length, soil type, and location.


The aforementioned photographs, together with the following description of the new raspberry variety ‘PS-10.028-58’, unless otherwise noted, are based upon observations taken during the 2016-2017 growing season in Watsonville, Calif. Primocane measurements and ratings were taken from plants of ‘PS-10.028-58’ dug from a nursery located in Siskiyou County, Calif. during the middle of October 2015 and planted approximately 3 to 4 weeks later in Watsonville, Calif. The approximate age of the observed primocane plants is 7 to 8 months. Floricane measurements and ratings were taken from the same planting of ‘PS-10.028-58’ at an approximate age of 16 to 18 months. Yield observations and fruit quality characteristics are averaged from three years of data collected from the 2013 through 2016 production seasons. Flower measurements and characteristics are from secondary flowers unless otherwise noted. Fruit characteristics and measurements are from secondary fruit unless otherwise noted. Foliage characteristics and measurements are from 3-foliate foliage unless otherwise noted.


Color terminology where noted follows The R.H.S. Colour Chart Fifth Edition, Royal Horticultural Society, London, United Kingdom (1966).


The following Tables 3-7 describe fruit, plant, foliage, flower and pest/disease characteristics of the new raspberry ‘PS-10.028-58’ in comparison to the similar raspberry varieties ‘GRANDEUR’ (patented, U.S. Plant Pat. No. 20,459).
