Description
Botanical designation: Prunus persica var. nucipersica.
Variety denomination: ‘Polar Sweet’.
1. 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.
2. Prior Varieties
Among the existing varieties of nectarine trees, which are known to us, and mentioned herein, ‘Arctic Queen’ Nectarine (U.S. Plant Pat. No. 8,094) and our proprietary non-patented nectarine selections ‘215LV498’, ‘120LH142’ and ‘381LN4’.
Not applicable.
The new variety of nectarine tree (Prunus persica var. nucipersica) was originated by us in our experimental orchard located near Modesto, Calif. as an open pollinated seedling selection from seed collected from our proprietary non-patented nectarine selection with the field identification number ‘215LV498’. The proprietary seed parent ‘215LV498’ originated as a second generation seedling from the cross of our proprietary non-patented nectarine seedling selections ‘120LH142’ and ‘381LN4’. We planted and maintained a large group of these open pollinated seedlings on their own root system. Under close and careful evaluation we recognized the desirable tree and fruit characteristics of the present variety and selected it in 2006 for asexual propagation and commercialization.
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 productive and regular bearer of large size, white flesh, clingstone fruit. The fruit is further characterized by having mild, sweet, sub-acid flavor with excellent eating quality. In comparison to its immediate seed parent ‘215LV498’ nectarine (non-patented) the fruit of the new variety is larger in size and is approximately 5 days later in maturity. In comparison to the commercial variety ‘Arctic Queen’ Nectarine (U.S. Plant Pat. No. 8,094) the fruit of the new variety is clingstone instead of freestone and is approximately 8 days later 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 5 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 5 year old specimens grown near Modesto, Calif., with color in accordance with Munsell Book of Color published in 1958.
