Patent Grant
PP18806
Latin name of the genus and species of the plant claimed: Rubus idaeus.
Variety denomination: ‘PS-1852’.
The present invention relates to a new and distinct raspberry variety designated as ‘PS-1852’. This new variety is a result of a controlled cross made by the inventor, Stephen M. Ackerman, in 1995 between raspberry variety ‘PS-1094’ (an unpatented Plant Sciences, Inc. selection) and raspberry variety ‘PS-1316’ (an unpatented selection). 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 1997. After its selection, the new variety was further asexually propagated by dormant canes, roots and non-dormant root shoot cuttings in both Santa Cruz County, Calif. and San Joaquin 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.
‘PS-1852’ 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 August through December on primocanes and in the ensuing year from May through July on the floricanes. The following traits have been repeatedly observed and are determined to be unique characteristics of ‘PS-1852’, which in combination distinguish this raspberry plant as a new and distinct variety:
The raspberry varieties that are believed to be most closely related to the new raspberry variety ‘PS-1852’ are the raspberry variety ‘PS-1049’ (patented, U.S. Plant Pat. No. PP 10,142), and the raspberry variety ‘PS-1703’ (patented, U.S. Plant Pat. No. PP 15,151).
In comparison to the similar raspberry varieties ‘PS-1049’ and ‘PS-1703’, ‘PS-1852’ differs by the following combination of characteristics described in Table 1:
For identification a series of molecular markers have been determined for this new variety.
The accompanying color photographs illustrate the overall appearance of typical specimens of the new raspberry variety, ‘PS-1852’, 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-1852’. The depicted plant and plant parts of the new raspberry variety ‘PS-1852’ were taken in Watsonville, Calif. and are approximately 7 to 10 months old.
‘PS-1852’ 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-1852’, unless otherwise noted, is based on observations taken during the 2006 growing season in Watsonville, Calif. Primocane measurements and ratings were taken from plants of ‘PS-1852’ dug from a nursery located in San Joaquin County, Calif., during the middle of December, 2005, 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 plants of ‘PS-1852’ dug from a nursery located in San Joaquin County, Calif., during the middle of December, 2004, and planted approximately 3 to 4 weeks later in Watsonville, Calif. The approximate age of the observed floricane plants is 16 to 18 months. Yield observations and fruit quality characteristics are averaged from three years of data collected from the 2004 through 2006 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 Munsell Book of Colors, Munsell Color, Baltimore, Md. (1976).
