Blueberry plant named ‘DrisBlueTwentyTwo’

Abstract

A new and distinct variety of blueberry plant named ‘DrisBlueTwentyTwo’ is disclosed. ‘DrisBlueTwentyTwo’ was selected as a strong evergreen blueberry variety with early and high yield. Fruit of ‘DrisBlueTwentyTwo’ are large, with balanced sugars and acids, firm crisp texture, and good bloom. Plants of ‘DrisBlueTwentyTwo’ are precocious and fruit on both one-year-old and current season's shoots.

Description

Latin name:

Botanical classification: Vaccinium corymbosum L.

Varietal denomination: The varietal denomination of the claimed variety of blueberry plant is ‘DrisBlueTwentyTwo’.

BACKGROUND OF THE INVENTION

Blueberry plants are perennial flowering plants with indigo-colored berries from the section Cyanococcus within the genus Vaccinium. Many commercially sold species with English common names, including blueberry, are currently classified in section Cyanococcus of the genus Vaccinium and come predominantly from North America. Many North American native species of blueberries are grown commercially in the Southern Hemisphere in Australia, New Zealand, and South American nations.

Vaccinium corymbosum, the northern highbush blueberry, is a North American species of blueberry which has become a food crop of significant economic importance. It is native to eastern Canada and the eastern and southern United States, from Ontario east to Nova Scotia and south as far as Florida and eastern Texas. It has been naturalized in Europe, Japan, New Zealand, and the Pacific Northwest of North America. Other common names include blue huckleberry, tall huckleberry, swamp huckleberry, high blueberry, and swamp blueberry.

Blueberries are usually erect, prostrate shrubs that can vary in size from approximately four inches to approximately 13 feet in height. In the commercial production of blueberries, the smaller species are known as “lowbush blueberries”, while the larger species are known as “highbush blueberries”.

Blueberry bushes typically bear fruit in the middle of the growing season. However, fruiting times can be affected by local conditions such as altitude and latitude. As such, peak crop can vary from May to August in the northern hemisphere, depending upon these conditions.

Blueberries are a popular fruit that is typically consumed as fresh fruit, individually quick frozen (IQF) fruit, or in prepared foods, such as purées, juices, jellies, jams, baked goods, snack foods, and cereals.

Blueberry is an important and valuable fruit crop. Accordingly, there is a need for new varieties of blueberry plant. In particular, there is a need for improved varieties of blueberry plant that are stable, high yielding, and agronomically sound.

SUMMARY OF THE INVENTION

In order to meet these needs, the present invention is directed to an improved variety of blueberry plant. In particular, the invention relates to a new and distinct variety of blueberry plant (Vaccinium corymbosum L.), which has been denominated as ‘DrisBlueTwentyTwo’.

Blueberry plant variety ‘DrisBlueTwentyTwo’ was discovered in Hillsborough County, Fla. in April of 2013 and originated from a cross between the proprietary female parent blueberry plant ‘196H 3’ (unpatented) and the proprietary male parent blueberry plant ‘7J301’ (unpatented). The original seedling of the new variety was first asexually propagated via softwood cuttings in Santa Cruz County, Calif. in July of 2013.

‘DrisBlueTwentyTwo’ was subsequently asexually propagated via softwood cuttings and tissue culture and underwent further testing in Ventura County, Calif. for five years (2014 to 2019). The present blueberry variety has been found to be stable and reproduce true to type through successive asexual propagations via softwood cuttings and shoot tissue culture.

‘DrisBlueTwentyTwo’ exhibits the following distinguishing characteristics when grown under normal horticultural practices in Ventura County, Calif.:

• • 1. Semi-upright plant growth habit;
  • 2. Elliptic leaf shape; and
  • 3. Entire leaf margin.

‘DrisBlueTwentyTwo’ was selected as a strong evergreen blueberry variety with early and high yield. Fruit of ‘DrisBlueTwentyTwo’ are large, with balanced sugars and acids, firm crisp texture, and good bloom. Plants of ‘DrisBlueTwentyTwo’ are precocious and fruit on both one-year-old and current season's shoots.
