Vaccinium plant named ‘ZF06-089’

Abstract

A new and distinct variety of Vaccinium plant, herein referred to by its cultivar name, ‘ZF06-089’, is provided which displays greenish-white colored inflorescence. The flower bud just before opening is oval shape and the leaves are ovate shape. The foliage is medium green colored. Moderately vigorous, spreading to compact growth habit is exhibited.

Description

Botanical/commercial classification:

Latin name of genus and species of plant claimed: Vaccinium corymbosum.

Variety denomination: ‘ZF06-089’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Vaccinium plant botanically known as Vaccinium corymbosum and hereinafter referred to by the cultivar name ‘ZF06-089’.

The new cultivar originated in a controlled breeding program in Lowell, Oreg. during April 2003. The objective of the breeding program was the development of superior Vaccinium cultivars that meet the evolving needs of the blueberry and home enthusiast industries.

The new Vaccinium cultivar is the result of cross-pollination. The female parent (i.e., seed parent) of the new cultivar is ‘Toro’, (non-patented) and is characterized by its pink to white colored inflorescences, dark green foliage color, and moderate growth vigor with a stocky and compact growth habit. The male parent (i.e., pollen parent) of the new cultivar is ‘FLX-2’ (U.S. Plant Pat. No. 19,381) and is characterized by its pink to white colored inflorescences, blue-green colored foliage, and moderate growth vigor with spreading growth habit.

The parentage can be summarized as follows:‘Toro’ x ‘FLX-2’

The new cultivar was obtained and selected as a single flowering plant within the progeny of the above stated cross-pollination during July 2008 in a controlled environment in Lowell, Oreg.

Asexual reproduction of the new cultivar by softwood stem cuttings since 2012 in Lowell, Oreg. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The new cultivar of the present invention possesses the following combination of characteristics, which have been repeatedly observed and can be used to distinguish ‘ZF06-089’ as a new and distinct cultivar of Vaccinium plant:

• • (a) provides greenish-white colored inflorescences,
  • (b) exhibits medium green colored foliage, and
  • (c) forms moderately vigorous, spreading to compact growth habit.

The new variety can be readily distinguished from its ancestors. More specifically, ‘Toro’ (i.e., seed parent) exhibits a less prostrate growth habit and produces a higher yield of fruit compared to the new variety and forms pink to white colored inflorescence whereas the new variety forms greenish-white colored inflorescence. Additionally, ‘FLX-2’ (i.e., pollen parent) exhibits a decreased hardiness and narrower leaves compared to the new variety and forms blue-green colored foliage, whereas the new variety forms medium green colored foliage. Moreover, the new variety can be readily distinguished from non-parental related similar varieties. Of the many commercially available Vaccinium cultivars, the most similar in comparison to the new cultivar is ‘ZF06-043’ (U.S. Plant Pat. No. 23,325). However, plants of the new cultivar differ from plants of ‘ZF06-043’ in at least the following characteristics:

• • 1. Plants of the new cultivar have a more uniform and spreading growth habit than plants of ‘ZF06-043’;
  • 2. Plants of the new cultivar have larger foliage than plants of ‘ZF06-043’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows, as nearly true as it is reasonably possible to make the same in color illustrations of this type, a typical specimen of the new variety. The illustrated Vaccinium plant of the new variety was approximately three years of age and was grown in the ground in Lowell, Oreg. during July 2017.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors described herein is that of The Royal Horticultural Society (R.H.S. Colour Chart, London, England, 2015 edition), except where general color terms of ordinary significance are used. The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The color values of the flowers were determined in April 2019 and the color values of all other plants parts were determined in July 2019 under natural light conditions in Cochranville, Pa. Measurements and numerical values represent averages of typical plants.
