USPP36984P2 - Strawberry plant named ‘GF Belle’ - Google Patents

Abstract

A new and distinct variety of strawberry plant named ‘GF Belle’ is described here. This new short-day strawberry variety is characterized by moderate vigor plants producing attractive conical fruit, which has a great, sweet strawberry flavor, and a desirable glossy light red exterior color. The variety is fully remontant in cool coastal areas of California, producing high quality fruit all season long. This variety also has a very open canopy, which allows ease of picking and spraying.

Description

Latin name of the genus and species of the plant claimed: Botanical classification: Fragaria x ananassa.

Variety denomination: The new strawberry denomination is ‘GF Belle’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of strawberry named ‘GF Belle’. This new short-day strawberry variety is the result of a controlled cross in an ongoing breeding program made in 2017. The controlled cross, conducted in an ongoing breeding program, which resulted in the ‘GF Belle’ variety was between a strawberry variety designated ‘Sweet Ann’, (U.S. Plant Pat. No. 22,472), and a strawberry variety designated ‘001R11’, (unpatented).

The controlled cross was carried out in a breeding program in Redding, California, USA. Pollen taken from the field of a ‘001R11’ plant pollinated a female ‘Sweet Ann’ plant in a greenhouse. The flowers were emasculated to remove all pollen sources, and so that no other pollen could contaminate the procedure.

Strawberries developed, were harvested and the seeds resulting from this cross were extracted and germinated in a greenhouse in Redding, California, USA. The resulting seedlings were transplanted to Shastina, California in 2018, grown for an additional period and allowed to propagate asexually via stolons. Plants were then harvested and planted in breeding test plots in early to mid-October in: Oxnard, California (Ventura County); and slightly later in Moss Landing, California (Monterey County). The selection of the new variety was first made in Oxnard, California, and designated ‘122X08’ in 2018. This selection was later named ‘GF Belle’. The new variety was further propagated asexually by stolons in breeding plots in: Macdoel, California (Siskiyou County); and Manteca, California (San Joaquin County).

The new variety has also been “meristemed.” Small pieces of plant material (approximately 0.5 mm in diameter), consisting of the undifferentiated meristem tissue and one or two leaf primordia, were removed from the buds on crowns of young daughter plants, then placed on nutrient medium, and new plants were grown from them. Planting stock from the “meristemed” plants are growing in a screenhouse located in Redding, California.

The propagules of ‘GF Belle’ are identical to the original plant in all distinguishing characteristics: accordingly, the propagation has demonstrated that the traits disclosed herein remain fixed and true to type through successive generations of asexual reproduction.

COMPARISON TO PARENT VARIETIES

‘GF Belle’ produces very high quality, large, firm berries, which are attractive, and which have great flavor. The primary market for the ‘GF Belle’ variety is for fresh market sales of the fruit. The berries produced by the ‘GF Belle’ variety are relatively early fruiting, enabling growers to capture early market windows. The open canopy of ‘GF Belle’ also allows for more airflow, and more visible fruit for better spray coverage and ease of picking.

The female parent, ‘Sweet Ann’, is a day neutral (DN) variety characterized as a vigorous plant which produces large to very large, conical fruit. The fruit has an exceptional flavor, and ‘Sweet Ann’ has an open plant architecture as does ‘GF Belle’. The male pollen parent, ‘001R11’, is a short-day plant, characterized by its large, firm, conical fruit which has a dark red exterior and interior color. Plants of ‘001R11’ are high vigor, with moderately dense foliage, and are mid-season producing.

SUMMARY OF THE INVENTION

‘GF Belle’ is a short-day variety exhibiting the following combination of characteristics, which have been observed repeatedly, and which distinguish this strawberry plant as a new and distinct variety:

• • 1. The variety produces large sized fruit;
  • 2. The fruit is well shaped conical;
  • 3. The fruit is attractive, having a glossy red exterior and interior;
  • 4. The fruit is sweet tasting, with great flavor;
  • 5. The variety produces a high volume of marketable fruit;
  • 6. The plants of the variety maintain an open architecture; and,
  • 7. The variety is fully remontant in a cool, coastal environment.

‘GF Belle’ fruit demonstrates characteristics and qualities that are desired by fresh market strawberry sales companies. The moderate red color is preferred by many shippers of fresh strawberries, as darker berries are often viewed as overripe by buyers, than are lighter colored berries. ‘GF Belle’ is also a firm berry, which should lend well to a fresh market where shipping can be a major factor. The vigor is moderate, and the density of ‘GF Belle’ plants are more open, with flowers that extend slightly over the canopy, allowing for adequate pollination. Fruit is easily seen and accessible on the shoulders of the beds allowing for ease of picking. This moderate vigor and open canopy hold an advantage over dense canopies in that spray coverage is allowed to penetrate more efficiently over denser varieties, and berries are often able to dry faster after rain events.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

‘GF Belle’ is a new and distinct variety of strawberry, known scientifically as Fragaria x ananassa. It is the result of a cross between its female parent, ‘Sweet Ann’, and its male parent ‘001R11’. ‘Sweet Ann’ is a day neutral variety, while ‘001R11’ is characterized by being a short-day variety. Both parents are remontant in cool coastal environments. ‘GF Belle’ is a short-day variety that has remontant or ever-bearing tendencies in temperate coastal environments and is partially remontant in warmer inland environments like its parents. Plants of ‘GF Belle’ bloom only once in our high elevation nursery, and do not bloom in the summer heat of our low elevation nursery location in Manteca, CA, consistent with other short-day varieties. The plants of the new variety have a moderate vigor and produce multiple crowns during the growing season. ‘GF Belle’ exhibits several characteristics which are improvements over one or both of its parent varieties, and other known cultivars. The characteristics of ‘GF Belle’ were observed in plants aged about 9 months from planting. These characteristics and comparisons with other cultivars are discussed following.

The fruit size of ‘GF Belle’ is large, slightly smaller than its ‘Sweet Ann’ parent, and similar in size, to its other parent ‘001R11’. The size of fruit of ‘GF Belle’ is ideal where it is not so large it could be damaged in containers, but not too small to allow for efficient picking and packing. The fruit of ‘GF Belle’ also hangs down on the shoulder of the bed to allow for highly visible fruit and ease of picking.

‘GF Belle’ produces mostly conic fruit similar to ‘001R11’, while the fruit of ‘Sweet Ann’ is mostly long conical. The fruit of ‘GF Belle’ generally ripens evenly from the tip to the shoulders of the berry, resulting in a uniform light red color over the whole fruit, but has a propensity of developing a seedy tip in certain conditions. In contrast, the fruit of ‘Sweet Ann’ often has a shoulder that does not ripen all the way to the calyx. The fruit of ‘GF Belle’ is mostly absent of creases and is generally smooth and has a firmness that is between its two parents, where it is slightly firmer than ‘Sweet Ann,’ and on par with ‘001R11’.

The data set forth for ‘GF Belle’ in Tables 1, 2, and 3 was collected in July 2023 from plants grown at a test plot in Moss Landing, Monterey County, California. Color terminology where noted herein was measured using a handheld Konica Minolta CR-400 colorimeter.

In Table 1, the observed characteristics of ‘GF Belle’ are set forth.

Flowering and Fruit

‘GF Belle’ is a short-day variety that has ever-bearing tendencies under certain temperature and horticultural conditions. This has been seen where plants grown in a cool, coastal climate have continuously flowered throughout the growing season, while in nursery production in Manteca where summer temperatures are hot, plants do not flower repeatedly. While ‘Miss Jo’ has similar inflorescences size to ‘GF Belle’, ‘Ashley Jay’ has shorter inflorescences. When compared to their individual plant size, all three varieties produce flowers that are near or above the canopy level, leaving flowers exposed to pollinators, with ‘GF Belle’ having most flowers exposed. The light red exterior color of the fruit of ‘GF Belle’ is similar in color to that of ‘Ashley Jay’ and ‘Miss Jo’, however ‘GF Belle’ has a high gloss to it, similar to that of ‘Miss Jo’. The fruit of ‘GF Belle’ has good culinary qualities, including great shape, large size, light red color, and a great strawberry flavor. The fruit storability has not been measured but the fruit retains good physical characteristics and appearance for several days at room temperature and up to a week in common refrigerator conditions of roughly 3° C.

In Table 3, comparative data for flower and fruit characteristics for ‘Ashley Jay’, ‘Miss 9 Jo’, and ‘GF Belle’, are set forth.
