Latin name of the genus and species of the plant claimed: Rubus idaeus.
Variety denomination: ‘PS-15.031-85’.
BACKGROUND OF THE INVENTION The present invention relates to a new and distinct fall bearing raspberry variety designated as ‘PS-15.031-85’. This new variety is a result of a controlled cross made in 2015 in Watsonville, California between raspberry variety ‘MAJESTIC’ (patented, U.S. Plant Pat. No. 31,716) as the female parent and raspberry variety ‘RR 12.050-29’ (unpatented) as the male parent in an ongoing breeding program. The variety is botanically known as Rubus idaeus and was tested as RR 15.031-85 and PS-3185.
The seedling resulting from the aforementioned cross was asexually propagated by dormant canes in Santa Cruz County, California and was subsequently selected by the inventor from a controlled breeding plot in Watsonville, California in 2017. After its selection, the new variety was further asexually propagated by dormant canes, roots and non-dormant root shoot cuttings in Watsonville (Santa Cruz County), Manteca (San Joaquin County), and Macdoel (Siskiyou County), California. The new variety was then extensively tested over the next several years in fruiting fields in Watsonville, California. 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-15.031-85’ 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 the floricanes. Damage to fruit and young leaves has been observed in summer temperatures at or above 95° F. (35° C.). No winter damage has been observed on fruiting plants in off-cycle (winter) production regions of USDA climate zones 9b and above. No winter damage has been observed on dormant plants in on-cycle (summer) production regions of USDA climate zones 7b-9b. In climate zones below this, winter hardiness is unknown for ‘PS-15.031-85’. ‘PS-15.031-85’ is not drought tolerant and requires frequent irrigation to maintain proper plant health. The following traits have been repeatedly observed and are determined to be unique characteristics of ‘PS-15.031-85’, which in combination distinguish this raspberry plant as a new and distinct variety:
-
- 1. Dark red spines
- 2. Medium fruit yield
- 3. Moderate 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-15.031-85’ is the raspberry variety ‘MAJESTIC’ (patented, U.S. Plant Pat. No. 31,716). In comparison to the similar raspberry variety ‘MAJESTIC’, ‘PS-15.031-85’ 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-15.031-85’ 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-15.031-85’. The depicted plant and plant parts of the new raspberry variety ‘PS-15.031-85’ were taken in Watsonville, California and are approximately 2 to 16 months old:
FIG. 1 shows typical primocane fruit shape, color and gloss characteristics of ‘PS-15.031-85’ taken in the month of October 2022;
FIG. 2 shows typical shape, gloss, coloration, foliate and rugosity characteristics of ‘PS-15.031-85’ taken in the month of October 2022;

FIG. 4 shows typical floricane plant characteristics of ‘PS-15.031-85’ taken in the month of June 2023.
DETAILED BOTANICAL DESCRIPTION ‘PS-15.031-85’ 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-15.031-85’, unless otherwise noted, are based upon observations taken during the 2022-2023 growing season in Watsonville, California. Primocane measurements and ratings were taken from plants of ‘PS-15.031-85’ dug from a nursery located in Siskiyou County, California during the middle of October 2021 and planted approximately 3 to 4 weeks later in Watsonville, California. 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-15.031-85’ 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 2020 through 2023 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 Sixth Edition, Royal Horticultural Society, London, United Kingdom (2015).
The following Tables 3-7 describe fruit, plant, foliage, flower and pest/disease characteristics of the new raspberry ‘PS-15.031-85’ in comparison to the similar raspberry variety ‘MAJESTIC’ (patented, U.S. Plant Pat. No. 31,716).
