Description
Botanical designation: Prunus persica var. nucipersica.
Variety denomination: ‘Polar Zee’.
Field of the Invention
In the field of plant genetics, we conduct an extensive and continuing plant-breeding program including the organization and asexual reproduction of orchard trees, and of which plums, peaches, nectarines, apricots, cherries, almonds and interspecifics are exemplary. It was against this background of our activities that the present variety of nectarine tree was originated and asexually reproduced by us in our experimental orchard located near Modesto, Stanislaus County, Calif.
Prior Varieties
Among the existing varieties of nectarine trees, which are known to us, and mentioned herein, ‘Honey Haven’ Nectarine (U.S. Plant Pat. No. 12,393) and ‘Polar Magic’ Nectarine (U.S. Plant patent application Ser. No. 14,756,155).
Not applicable.
The new and distinct variety of nectarine tree (Prunus persica var. nucipersica) was developed by us in our experimental orchard located near Modesto, Calif. from open pollinated seed collected from ‘Polar Magic’ Nectarine (U.S. Plant patent application Ser. No. 14,756,155). A large number of these open pollinated seedlings were budded onto older established trees of ‘Nemaguard’ Rootstock (non-patented) to enhance earlier fruit production. Under close and careful observation the present budded seedling exhibited desirable fruit and tree characteristics and was selected in 2009 for additional asexual propagation and commercialization.
In 2009 asexual reproduction of the new and distinct variety of nectarine tree was by budding to ‘Nemaguard’ Rootstock (non-patented), as performed by us in our experimental orchard located near Modesto, Calif., and shows that reproductions run true to the original tree and all characteristics of the tree and its fruit are established and transmitted through succeeding asexual propagations.
The present new variety of nectarine tree (Prunus persica var. nucipersica) is of large size, vigorous, upright growth and a regular and productive bearer of large size, white flesh, clingstone fruit. The fruit is further characterized by its attractive red skin color and very good flavor and eating quality. In comparison to its nectarine seed parent ‘Polar Magic’ (U.S. Plant patent application Ser. No. 14,756,155) the fruit of the new variety has a higher degree of Brix of 19.0° compared to 14.0° and is approximately 4 days later in maturity. In comparison to the commercial variety ‘Honey Haven’ Nectarine (U.S. Plant Pat. No. 12,393) the fruit of the new variety has white flesh compared to yellow and is approximately 6 days earlier in maturity.
The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new nectarine variety. The illustration shows the upper and lower surface of the leaves, an exterior and sectional view of a single fruit divided in its suture plane to show flesh color, pit cavity and the stone remaining in place. The photographic illustration was taken shortly after being picked (shipping ripe) from a 6 year old tree and the colors are as nearly true as is reasonably possible in a color representation of this type.
The following is a detailed botanical description of the new variety of nectarine tree, its flowers, foliage and fruit, as based on observations of 6 year old specimens grown near Modesto, Calif., with color in accordance with Munsell Book of Color published in 1958.
