USPP27747P2 - Punica granatum plant named ‘PQ2009’ - Google Patents

Abstract

A new cultivar of pomegranate tree, ‘PQ2009’, that is characterized by its flowers that consistently have 6 petals and 6 sepals that are bright orange in color and bloom from spring until first frost in Georgia, its flowers that are borne primarily at the terminals on soft to semi-hard wood, its foliage that is initially bronze in color maturing to a medium green color and persists until freeze (survives frosts), its production of quality tasting fruit on one year-old container grown plants that ripen in late summer to late fall, and its fruit that is sweet with low astringency and little aftertaste.

Description

Botanical classification: Punica granatum.

Varietal denomination: ‘PQ2009’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of pomegranate tree, botanically known as Punica granatum and hereinafter referred by its cultivar name, ‘PQ2009’. ‘PQ2009’ is a new cultivar of pomegranate tree that blooms from spring to fall, produces sweet tasting fruit, and is both ornamental and productive as a large container or landscape plant.

‘PQ2009’ was selected by the Inventor as a seedling that arose from seed sown in 2009 from fruit of Punica granatum grown by a home gardener (cultivar name if any and patent status is unknown) that had been open pollinated (the male parent is unknown). The fruit of the female parent plant exhibited yellow skin, bright red arils, and a taste that was sweet, low in acidity and low in astringency and the goal was to obtain a new cultivar of Punica granatum that combined those desirable fruit characteristics with a floriferous blooming habit and good fruit production. ‘PQ2009’ was selected as a single unique plant in 2012 from among 100 seedlings that were evaluated.

Asexual propagation of the new cultivar was first accomplished by stem cuttings under the direction of the Inventor in Alpharetta, Ga. in February of 2011. Asexual propagation by stem cuttings has determined that the characteristics of this cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new pomegranate tree. These attributes in combination distinguish ‘PQ2009’ as a unique cultivar of pomegranate tree.

• • 1. ‘PQ2009’ exhibits flowers that consistently have 6 petals and 6 sepals that are bright orange in color and bloom from spring until first frost in Georgia.
  • 2. ‘PQ2009’ exhibits flowers that are borne primarily at the terminals on soft to semi-hard wood.
  • 3. ‘PQ2009’ exhibits foliage that is initially bronze in color maturing to a medium green color and persists until freeze (survives frosts).
  • 4. ‘PQ2009’ exhibits production of quality tasting fruit on one year-old container grown plants.
  • 5. ‘PQ2009’ exhibits fruit that ripens in late summer to late fall with late production persisting on the tree through winter for ornamental value.
  • 6. ‘PQ2009’ exhibits fruit that is sweet with low astringency and little aftertaste.

The fruit of the female parent plant of ‘PQ2009’ differs from ‘PQ2009’ in having yellow fruit that does not turn red at ripening. ‘PQ2009’ can be compared to Punica granatum cultivars ‘Wonderful’ (not patented), ‘Granada’ (not patented), ‘Kamel’ (U.S. Plant Pat. No. 21,966), and ‘EMEK’ (U.S. Plant Pat. No. 21,907). ‘Wonderful’ is similar to ‘PQ2009’ in having edible, medium soft seeds. ‘Wonderful’ differs from ‘PQ2009’ in having fruit that can get larger in size, in having fruit with darker red colored skin and arils, in having fruit with a more astringent, wine-like flavor, and in having foliage that is thicker and glossier. ‘Granada’ is similar to ‘PQ2009’ in having fruit that is low in acidity. ‘Granada’ differs from ‘PQ2009’ in having fruit with skin that is darker red and turns red before ripening, in having foliage that is thicker and glossier, and in having flowers that are red in color. ‘Kamel’ differs from ‘PQ22009’ in having fruit with darker red colored skin, in having flowers that are redder in color, and in having flowers with a variable numbers of 5-7 petals. ‘EMEK’ differs from ‘PQ2009’ having fruit that ripens earlier, in having flowers with a variable number of 5-7 petals, and in having flowers that are deep orange-red in color.
