The new variety of strawberry was created in a breeding program by my crossing two parents from among a group of seedlings which were obtained from a free pollination of 32 different varieties and seedlings; in particular, by crossing as seed parent a variety designated 86-037 and as a pollen parent a variety designated 86-096. Both parental varieties are proprietary and have not been commercialized.
The resulting seedling of the new variety was grown and asexually reproduced by runners in Soria, Spain, 3°W., 41°N., 3000 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.
The present invention relates to a new and distinct strawberry variety genus L. fragaria. The varietal denomination of the new variety is `Aires`. Among the charcteristics which distinguish the new variety from other varieties of which I am aware are a combination of traits which include inflorescence that appears beneath the foliage and abundant production of conical-shaped fruit.
The new variety is closest to the variety `Selva` (U.S. Plant Pat. No. 5,266), but is distinguished therefrom by the following characteristics possessed by `Aires` which are different than, or not possessed by, Selva.
1. `Selva` plant is flatter and less vigorous than `Aires`.
2. Terminal leaflet of `Selva` is longer than broad whereas in `Aires` it is as long as broad.
3. Shape of the terminal leaflet base of `Selva` is acute and in `Aires` it is rounded.
4. Inflorescence in `Selva` is level with foliage and in `Aires` it is beneath.
5. `Selva's petals are as long as broad. In `Aires` the petals are broader than long. The petal size of `Aires` is about 10 to 11 mm wide and about 8 to 9 mm long, whereas `Selva` petals are about 9 mm wide and about 9 mm long.
6. `Selva` Fruit is bigger than `Aires` fruit.
7. Fruit of `Selva` is less bright but more even in color than `Aires`. As can be seen by the comparison in FIGS. 8 and 9, the color of `Selva` is darker than that of the new variety (designated 9079060).
As can be seen by commparison of FIGS. 9 and 10, the fruit color of new variety is brighter red than that of `Selva`. The difference in the core is also evident from the illustrations.
8. Insertion of achenes in fruit is level with surface whereas in `Aires` insertion is below surface.
9. Insertion of calyx in fruit is level in `Selva` whereas in `Aires` it is in a basin.
10. `Selva` fruit is firmer than `Aires`.
11. Flesh color of `Selva` is orange-red and is pale red in `Aires`.
12. `Selva` fruit is less acid than `Aires`.
The accompanying photographs show typical specimens of the new variety, designated 90-79-060 in the illustrations, including fruit, foliage and flower, in color as nearly true as it is reasonably possible to make in color illustrations of this character.
FIG. 1 shows typical fruit in cross section illustrating the typical flesh and flesh coloration, conspicuous core and core cavity and conical shape;
FIG. 2 shows whole and sliced, detached fruit;
FIGS. 3 and 4 show the fruit against the background of the top surface of the foliage;
FIG. 5 shows the flower and reproductive organs of the new variety;
FIG. 6 shows the top and undersurface of a typical foliose of the new variety;
FIG. 7 illustration shows a typical leave of the new variety;
FIGS. 8 and 9 show the fruit of the new variety (designated 9079060) and `Selva`, respectively; and
FIGS. 10 and 11 show cross-section of the fruit of the new variety (designated 9079060) and `Selva`, respectively.
The following detailed description of the new variety is based upon observations taken of plants and fruit grown "underglass", i.e. undertunnel, in a farm in Cartaya (Huelva), Spain, 7°W., 37°N., 45 feet elevation.
The 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.
The new variety is principally propagated by way of runners. Although propagation by runners is presently preferred, other known methods of propagating may be used. Strawberry plants root well after transplanting.
The term "blistering" used herein refers to the texture or rugosity inherent to leaves and is generally a constant characteristic.
`Aires` is a day neutral variety. It is about as strongly day-neutral as Selva, and less strong than `Irvine` (U.S. Plant Pat. No. 7,172) or Fern (U.S. Plant Pat. No. 5,267). `Aires` does not need any additional treatment to assure a sufficient flowering.
Production: Plant issued from high elevation nursery.
