CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to a Peruvian Breeder's Rights Application No. 92-2022 filed on Jan. 18, 2022, the entire contents of which is incorporated by reference herein.

BACKGROUND OF THE INVENTION

The present invention relates to a new Vaccinium corymbosum L. plant, which was selected from open pollination between ‘Biloxi’ (Not Patented) (Vaccinium corymbosum L., public plant) as the female (seed) parent and pollen from an unknown variety (Vaccinium corymbosum L.). Berry seeds of plants of the ‘Biloxi’ variety were collected from different fields located in Viru, La Libertad, Peru at the beginnings of 2016. 11805 seedlings at high density were planted under field conditions in December of the same year.

The seedlings were evaluated during 3 growing seasons (2017, 2018 and 2019) and the breeding method used was phenotypic recurrent selection. In December 2019 one of the seedlings, ‘BLUECSOL11’, was isolated due to its excellent quality fruit, long postharvest life, and high yield potential. ‘BLUECSOL11’ was asexually propagated by softwood cuttings to confirm the distinctness, and stability of the characteristics observed in another growing season. 5 rooted cuttings were planted in an experimental test plot located in Viru, La Libertad, Peru. From December 2020 until the present, said test plot has shown that the unique features of this new Vaccinium variety are stable and reproduce true to type in successive generations of asexual propagation. In addition, ‘BLUECSOL11’ was subsequently propagated by softwood cutting and tissue culture and an additional plot, with 29 plants were planted in December 2021 in the same location. This new plot has maintained up to the present the distinctness, and stability characteristics of the new variety of Vaccinium corymbosum L.

SUMMARY OF THE VARIETY

The following is a summary of the description of the new and distinct variety of blueberry ‘BLUECSOL11’ was selected in Viru, La Libertad, Peru in December 2019. ‘BLUECSOL11’ has not been observed under all environmental conditions. The phenotype may vary somewhat with variations in the environmental conditions such as temperature and light intensity, without, however, any variance in genotype. ‘BLUECSOL11’ is an evergreen blueberry variety with zero chill requirement. The following are the most distinguishing traits of this new variety: medium plant vigor, semi-upright growth habit, elliptical leaf shape, globose corolla shape and weak conspicuousness of ridges on corolla tube, oblate fruit shaped, large fruit-size, strong bloom intensity, medium sweetness, high acidity, and firm fruit.

‘BLUECSOL11’ was selected as an early variety, with overstanding yield potential, excellent fruit quality and post-harvest life.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs show typical bush, leaves, flower, and fruit characteristics of the new Vaccinium corymbosum L. ‘BLUECSOL11’. Colors shown are as accurate as can be reasonably reproduced by the photographic means. Photographs were taken of 2 and 4-year-old plants grown in fields of the test plot, located in Viru, La Libertad, Peru.
