Blackberry plant named ‘AGV-22’

Abstract

The new and distinct variety of blackberry plant ‘AGV-22’ is provided. The variety can be distinguished by its outstanding features of crunchy and sweet fruit, fruit with long shelf life, high firmness, and low regression.

Description

[0001] Latin name of the genus and species:

[0002] Botanical classification: a. Genus—Rubus subgenus Eubatus sect. Moriferi & Ursini.

[0003] Variety denomination: The new blackberry plant claimed is of the variety denominated ‘AGV-22’.CROSS REFERENCE TO RELATED APPLICATIONS

[0004] The application claims benefit under 35 USC § 119 to Mexican Plant Breeder's Right Registration Application No. MX_4534_NLI published on Apr. 18, 2024, for a blackberry plant with a variety denomination of ‘AGV-22’, which is herein incorporated by reference in its entirety.SUMMARY

[0005] The present invention relates to a new and distinct variety of blackberry, which has been given the variety denomination of ‘AGV-22’.

[0006] The new blackberry variety is a selection resulting from a sexual cross of blackberry plants in high tunnels / hoop houses at Los Reyes, Michoacán, Mexico in 2015, involving a seed parent known as ‘BG-36’ (unpatented) and a pollen parent known as ‘BG-52’ (unpatented).

[0007] The selection was subsequently evaluated for 3 years at Los Reyes, Michoacán, Mexico and 2 years at Techaluta de Montenegro, Jalisco, Mexico.

[0008] Asexual reproduction of the new variety by root cutting propagation since 2017 at Los Reyes, Michoacán, Mexico has demonstrated that the new variety reproduces true to type with all of the morphological characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

[0009] Selection criteria were fruiting primocane with fruit quality that has high firmness, sweet flavor (18° Bx) and low acidity (0.9 to 1.1 rate acidity—measured by ATAGO PAL-BX / ACID F5 (Multi-fruits) tool), high productivity, vigorous plants characterized by plants that grow easily in the spring and summer with an average of 2.4 cm per day, and resistance to pests and diseases.

[0010] Compared to its parents ‘AGV-22’ shows great expression of heterozygosity because it is more resistant than its parents to fungal pathogens. Unlike its parents, ‘AGV-22’ is highly resistant to Fusarium or Peronospora. Unlike its parents, ‘AGV-22’ is resistant to two-spotted spider mite (Tetranychus urtichae), and to redberry mite (Acalitus essigi). Compared to ‘Tupi’, ‘AGV-22’ is much more resistant to regression of fruit, and more resistant to fungal diseases like Fusarium. ‘Tupi’ and ‘AGV-22’ are similar in terms of resistance to other plagues.

[0011] The following characteristics of the new variety have been repeatedly observed and can be used to distinguish ‘AGV-22’ as a new and distinct variety of blackberry plant: crunchy and sweet fruit, fruit with long shelf life, high firmness, and low regression. ‘AGV-22’ demonstrates fruit firmness that is high enough to avoid leaking once the fruit is packaged and to create a crunchy experience when eaten. Its shelf life is about 17 days, the sweetness capacity is 18° Bx, and acidity rate is 0.9 to 1.1 (measured by ATAGO PAL-BX / ACID F5 (Multi-fruits) tool).PHOTOGRAPHS

[0012] The accompanying photographic illustrations show the typical appearance of the new variety ‘AGV-22’. The colors are as nearly true as is reasonably possible in a color representation of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describes the colors of the new plant.
