Strawberry plant named ‘Cristal’

Abstract

The present invention relates to a new and distinct strawberry variety. The varietal denomination of the new variety is ‘Cristal’. Among the characteristics which appear to distinguish the new variety from other varieties are a combination of traits which include inflorescence that appears above the foliage same size of calyx relative to corolla and abundant production of dark red colored, almost cylindrical shaped, and firm fruit, large fruit size, and early time of ripening.

Description

Botanical classification: Fragaria×ananassa Duch.

Varietal denomination: The new plant has the varietal denomination ‘Cristal’.

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 9261 (unpatented) and as pollen parent an undistributed strawberry parent designated 9045 (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 ‘Cristal’. Among the characteristics which appear to distinguish the new variety from other varieties are a combination of traits which include inflorescence that appears above the foliage, same size of calyx relative to corolla and abundant production of dark red colored, almost cylindrical shaped, and firm fruit, large fruit size, and early time of ripening (50% of plants with ripe fruits).

COMPARISON TO CLOSEST VARIETY

The new variety is closest to the variety ‘Aires’ (U.S. Plant Pat. No. 9,757), but is distinguished therefrom by the following characteristics possessed by ‘Cristal’ which are different than, or not possessed by, ‘Aires’ (U.S. Plant Pat. No. 9,757).

• • 1. ‘Aires’ (U.S. Plant Pat. No. 9,757) exhibit a plant more dense than ‘Cristal’.
  • 2. ‘Aires’ (U.S. Plant Pat. No. 9,757) shows a leaf color of upper side (RHS green group near 135 B to 135 A) more dark than ‘Cristal’ (RHS green group near 141 B to 141 A).
  • 3. Shape in cross section of the leaf in ‘Aires’ (U.S. Plant Pat. No. 9,757) is flat to slightly convex, than in ‘Cristal’ it is slightly concave.
  • 4. Glossiness of the leaf in ‘Aires’ (U.S. Plant Pat. No. 9,757) is less strong than in ‘Cristal’.
  • 5. In ‘Aires’ (U.S. Plant Pat. No. 9,757) the position of the inflorescence relative to foliage is beneath, in ‘Cristal’ it is above.
  • 6. Size of calyx relative to corolla of the flower in ‘Aires’ (U.S. Plant Pat. No. 9,757) is smaller and the relative position of petals is touching, than in ‘Cristal’ the size of calyx relative to corolla is same size and the relative position of petals is overlapping.
  • 7. The fruit shape of ‘Aires’ (U.S. Plant Pat. No. 9,757) is conical whereas in ‘Cristal’ is almost cylindrical.
  • 8. ‘Aires’ (U.S. Plant Pat. No. 9,757) shows a red fruit color (RHS red group near 44 A to 42 A), whereas in ‘Cristal’ it is an dark red fruit color (RHS red group near 46 B to 45 A).
  • 9. Band without achenes in fruit of ‘Aires’ (U.S. Plant Pat. No. 9,757) is absent or very narrow whereas in the fruit of ‘Cristal’ is narrow.
  • 10. The glossiness of fruit in ‘Aires’ (U.S. Plant Pat. No. 9,757) is medium whereas in the fruit of ‘Cristal’ is strong.

The differences in the leaf color of upper side of ‘Cristal’ (designated 00.44.194) and ‘Aires’ (U.S. Plant Pat. No. 9,757) (designated 90.79.060) are shown in FIG. 3. The differences in the fruits of ‘Cristal’ and ‘Aires’ (U.S. Plant Pat. No. 9,757) are shown in FIG. 6. These differences are maintained during the harvest season.

• • 11. ‘Cristal’ shows a firmness fruit slightly more than ‘Aires’ (U.S. Plant Pat. No. 9,757).
  • 12. Time of ripening in ‘Aires’ (U.S. Plant Pat. No. 9,757) is very early whereas in ‘Cristal’ is early.

Band without achenes in fruit of ‘Aires’ (U.S. Plant Pat. No. 9,757) (designated 90.79.060) is absent or very narrow whereas in the fruit of the new variety (designated 00.44.194) is narrow. The glossiness of fruit in ‘Aires’ (U.S. Plant Pat. No. 9,757) (designated 90.79.060) is medium whereas in the fruit of the new variety (designated 00.44.194) is strong.

FIGS. 7 and 8 show typical fruit of the new variety (designated 00.44.194) whole, sliced and in cross section, illustrating the typical flesh and flesh coloration (RHS red group near 43 B to 43 A), conspicuous core and core cavity, almost cylindrical shape and dark red fruit color (RHS red group near 46 B to 45 A).

DESCRIPTION OF THE NEW VARIETY

The following detailed description of the new variety is based upon observations taken of 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.). 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.

PROPOGATION

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

‘Cristal’ is a fully remontant (non flowering runners) variety and do not needs an induction to flowering by chilling (fresh plant) or with cold storage (referred to as a frigo). ‘Cristal’ 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: 15th Oct. 2007. Number of repetitions: 2. Plants per repetition: 225.

Comparison with ‘Aires’ (U.S. Plant Pat. No. 9,757). The new variety is compared with ‘Aires’ (U.S. Plant Pat. No. 9,757) (designated 90.79.060) in FIG. 1 and FIG. 2 and FIG. 3 and FIG. 4 and FIG. 5 and FIG. 6.
