The new variety of strawberry was created in a breeding program by 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 designed 85-20 and as pollen parent a variety designed 86-061. Both parental varieties are proprietary and have not been commercialized.
The resulting seedling of the new variety was grown and asexually propagated by runners in Soria, Spain, about 3° W, 41° N, 3000 feet evaluation. 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. The varietal denomination of the new variety is `Tudnew.` Among the characteristics which distinguish the new variety from other varieties are a combination of traits which include inflorescence that appears above the foliage and abundant production of red-colored, conical-shaped, very firm fruit and very large fruit size.
The new variety is closest to the variety `Chandler` (U.S. Plant Pat. No. 5262), but is distinguished therefrom by the following characteristics possessed by `Tudnew` which are different than, or not possessed by, `Chandler.`
1. `Chandler` exhibits more plant vigor than `Tudnew.`
2. Leaf surface undulation of `Chandler` is less than in `Tudnew.`
3. `Tudnew` has a darker green leaf color than `Chandler.` The differences in the leaves of `Chandler` and the new variety are shown in FIG. 7. These differences are maintained during the growing season.
4. In `Tudnew` the position of the inflorescence relative to foliage is above. In `Chandler` it is level with the foliage.
5. In `Tudnew` the petals are as long as broad. In `Chandler` they are broader than long. The differences in the ratio of length/width of the petals of `Chandler` and the new variety are shown in FIG. 8. These differences are maintained during the flowering season.
6. `Chandler` fruit is longer than broad. `Tudnew` fruit is much longer than broad and very large.
7. `Chandler` has an almost cylindrical shape. In `Tudnew` the shape is conical.
8. `Chandler` has a medium band without achenes and the insertion of achenes is level with surface; whereas, in `Tudnew` the band without achenes is broad and the insertion is below surface.
9. In `Chandler` the calyx segments appear clasping or detached; whereas, in `Tudnew` they are reflexed.
10. `Chandler` calyx is larger than the fruit, and in `Tudnew` it is the same size.
11. `Chandler` fruit is less firm than `Tudnew` fruit.
The accompanying photographs show typical specimens of the new variety, designated 92.H1.51 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. 2 shows whole and sliced detached fruit;
FIGS. 3 and 4 show the fruit against a 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 foliole of the new variety;
FIG. 7 shows a comparison of the foliage of the new variety (designated 92.H1.51) and of the variety `Chandler`;
FIG. 8 shows a comparison of the ratio length/width of the petals of the new variety (designated 92.H1.51) and of the variety `Chandler`; and
FIG. 9 shows a comparison of the size, shape, band without achenes and pose of the calyx segments of the new variety (designated 92.H1.51) and of the variety `Chandler.`
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, about 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.
The new variety is principally propagated by way of runners. Although propagation by runners is presently preferred, other known methods of propagating strawberry plants may be used. Strawberries root well after transplanting.
The term "blistering" used herein refers to the texture or rugosity inherent to leaves and is generally a constant characteristic.
`Tudnew` 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. `Tudnew` 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 a high elevation nursery.
Trials pursued in Cartaya (Huelva), Spain.
Date of planting.--Oct. 21, 1996.
Number of repetitions.--2.
Plants per repetition.--100.
Comparison with `Chandler`.--The new variety is compared with `Chandler` in FIGS. 7, 8, and 9.
