Strawberry plant named ‘A13-71’

Abstract

A new day-neutral strawberry plant named ‘A13-71’ is disclosed, with exceptional yield and flavor characteristics.

Description

Genus and species: Fragaria x ananassa Duch.

Variety denomination: ‘A13-71’.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

None

BACKGROUND OF THE INVENTION

‘A13-71’ is a product of a breeding program carried out by the inventor in the Andalucia region of Spain. ‘A13-71’ was one of several seedlings resulting from an uncontrolled cross made in the year 2013. The seeds resulting from the uncontrolled cross with unknown parents were germinated indoors and the resulting seedling was transplanted to the trial seedling field. ‘A13-71’ was selected in the Andalucia region of Spain in the year 2014 based on observations of its fruiting characteristics. In 2015, ‘A13-71’ was asexually propagated by rooting stolons and was expanded to 30 plants which were planted in replicated trials in the Andalucia region of Spain. The plants were observed and evaluated, and the next year they were expanded for further observation and evaluation. The breeders of ‘A13-71’ have sold the variety commercially under the Trademark name Cleopatra WB or Cleopatra Circle R Brand. Contrast is made with the ‘San Andreas’ (U.S. Plant Pat. No. 19,97) in reference to the shape of the fruit; ‘A13-71’ presents an ovoid and globose shape while ‘San Andreas’ presents a conical shape. The color of the leaves of the ‘San Andreas’ variety is dark green while ‘A13-71’ variety has medium green leaves. The achenes of the fruit of ‘San Andreas’ are below the surface while those of ‘A13-71’ are at the same height as the surface. Comparison is made with strawberry variety ‘BG-4316’ (U.S. Plant Pat. No. 23,255) known commercially in Europe as ‘Victory’. The plants of ‘A13-71’ variety produce a yield of 670.52 g per plant while ‘BG-4316’ presents a higher yield of 810.66 g per plant. The fruit of ‘A13-71’ has a firmness of 400 in the penetrometer while ‘BG-4316’ variety has a greater firmness of 414 in the penetrometer. The fruit of ‘A13-71’ has a lower brix of 7.3 than ‘BG-4316’ which contains a brix of 7.6. The fruit of ‘A13-71’ is partially remontant allowing the variety to have a production with greater precocity than other varieties allowing the commercial use in different markets. ‘A13-71’ is commercialized primarily in the fresh fruit market and secondarily in the frozen fruit market. Throughout several generations of asexual propagation, ‘A13-71’ has been observed to retain its distinctive characteristics and remain true to type.
