Strawberry plant named ‘PLANASA 02-32’

Abstract

The present invention relates to a new and distinct strawberry variety. The varietal denomination of the new variety is ‘PLANASA 02-32’. Among the characteristics which appear to distinguish the new variety from other varieties are a combination of traits which include big size of flower, a big size of calyx relative to corolla and abundant production of red colored, conical shaped, and big fruit size, and medium time of ripening.

Description

Botanical classification: Pragaria×ananassa ‘PLANASA 02-32’.

Varietal denomination: The new plant has the varietal denomination Duch.

BACKGROUND OF THE INVENTION

The new variety of strawberry was created in a breeding program by crossing two parents; in particular, by crossing as seed parent an undistributed strawberry parent designated ‘94-020’ (unpatented) and as pollen parent an undistributed strawberry parent designated ‘9719’ (unpatented). Female and male are selections from breeder's program of Planasa. Both parental varieties are property and have not been commercialized.

The resulting seedling of the new variety was grown and asexually propagated by runners in Segovia, Spain, 3° 59′W., 41° 22′N., 2742 feet elevation. Clones of the new variety were further asexually propagated and extensively tested. This propagation and testing has demonstrated that the combination of traits disclosed herein which characterize the new variety are fixed and retained true to type through successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct strawberry variety. The varietal denomination of the new variety is ‘PLANASA 02-32’. Among the characteristics which appear to distinguish the new variety from other varieties are a combination of traits which include big size of flower, a big size of calyx relative to corolla and abundant production of red colored, conical shaped, and big fruit size, and medium time of ripening (50% of plants with ripe fruits).

COMPARISON NEW VARIETY TO THE PARENTS

The new variety is distinguished therefrom its parents by the following characteristics possessed by ‘PLANASA 02-32’ which are different than, or not possessed, by the seed parent designated ‘94-020’ (unpatented) and the pollen parent designated ‘9719’ (unpatented).

• • 1. Seed parent ‘94-020’ (unpatented) is less vigorous than the plant of the new variety ‘PLANASA 02-32’.
  • 2. In seed parent ‘94-020’ (unpatented) the position of the inflorescence relative to the foliage is above, whereas in the new variety ‘PLANASA 02-32’ is level with.
  • 3. In seed parent ‘94-020’ (unpatented) and in pollen parent ‘9719’ (unpatented) the fruit size is smaller than in the new variety ‘PLANASA 02-32’.
  • 4. In pollen parent ‘9719’ (unpatented) the terminal leaflet is as long as broad, whereas in the new variety ‘PLANASA 02-32’ is longer than broad.

COMPARISON TO CLOSEST VARIETY

The new variety is closest to the variety ‘Sabrosa’ (U.S. Plant Pat. No. 16,558) and the variety ‘Camarosa’ (U.S. Plant Pat. No. 8,708), but is distinguished therefrom by the following characteristics possessed by ‘PLANASA 02-32’ which are different than, or not possessed by, ‘Sabrosa’ (U.S. Plant Pat. No. 16,558) or ‘Camarosa’ (U.S. Plant Pat. No. 8,708).

DESCRIPTION OF THE NEW VARIETY

The following detailed description of the new variety is based upon observations taken of 2 year old plants and fruits grown “underglass”, i.e. undertunnel, in the farm of La Mogalla in Cartaya (Huelva), Spain, 7° W., 37° N., 45 feet elevation.

The following description is in accordance with UPOV terminology and the color terminology herein is in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.), 3rd edition published in 1995. The color descriptions and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic and cultural conditions.

PROPAGATION

The new variety is principally propagated by way of runners. Although propagation by runners is presently preferred, other know methods of propagating strawberry plants may be used. Strawberries root well after transplanting.

The term “blistering” used herein refers to the texture or rugosity or surface ondulation inherent to leaves and is generally a constant characteristic.

GENERAL

‘PLANASA 02-32’ is a short day variety that needs an induction to flowering by chilling, such as occurs at a high elevation nursery (fresh plant) or with cold storage (referred to as a frigo). Usually a short time is sufficient. ‘PLANASA 02-32’ is self-fertile. It produces large quantity of pollen throughout the seasons and pollination is generally good as there are very few malformed fruit.

• Production: Plants described are from high elevation nursery. Trials pursued in Cartaya (Huelva), Spain.
• Date of planting (two years): 10 Oct. 2009 and 11 Oct. 2010.
• Number of repetitions (every year): 2.
• Plants per repetition (every year): 225.
