Abstract
A new and distinct variety of strawberry (Fragaria L.) called "Dorit" is disclosed. The variety is a cross between "Dover A" and "Nurit", which results in a variety that flowers several months earlier than other known strawberry varieties.
Description
This is a continuation of application Ser. No. 07/489,440 filed Mar. 6, 1990, now abandoned.
The present invention relates to a new and distinct variety of strawberry (Fragaria L.) called "Dorit". The variety was developed from an organized scientifically designated breeding program carried out at the Agricultural Research Organization, the Volcani Center, Bet Dagan, Israel. The variety is the product of selection of seedlings resulting from crosses between the strawberry varieties "Dover A" and "Nurit". The variety was asexually vegetatively propagated through runners and the reproduction ran true.
The new variety "Dorit" is able to grow in September and produce fruit starting in November and lasting until summer. The production of fruit beginning in November is two months earlier than any known variety of Fragaria L. The fruit of the "Dorit" variety is characterized by good taste, good shape and size as well as a long shelf life.
FIG. 1. Photograph of the "Dorit" variety illustrating the foliage and fruit.
FIG. 2. Photograph of the "Dorit" variety illustrating the fruit.
FIG. 3. Photograph of the "Dorit" variety illustrating the entire plant with both flowers and fruit.
The "Dorit" variety was grown in winter under polyethylene tunnels in Israel. "Dorit" is a short day variety that flowers earlier than other known and available short day length strawberry varieties. Flowering and fruit production is not affected by the use of polyethylene wind tunnels. This production procedure is utilized in normal agricultural practices by the skilled artisan and does not involve temperature or light control. Mother plants were stored at 0° C. from January through April. They were then planted in the nursery without further treatment. Runners with plantlets were produced during summer. These young plantlets were collected from the nursery in September and transferred to raised beds. Average temperatures at that time of the year are 30° C. during the day and 22° C. at night. Water and fertilizers were applied through drip irrigation. An example of an optimum planting date is between September 20th to the 25th with the approximate date of flowering on October 27, and the approximate date of first fruiting on November 27. "Dorit" flowering is not induced by chilling, but by natural exposure to short day length (long nights) characteristic of late fall and early winter. Color readings described herein were taken under natural light conditions and color identifications were made by reference to The Royal Horticultural Society Colour Chart (R.H.S.C.C.) except where common terms of color definition are employed.
The pertinent characteristics of the present invention are presented in Table 1 and Table 2. Additionally, the variety "Dorit" (1) has no tendency toward fruit malformation; (2) disease resistance appears normal in that no particular problematic conditions arose during trials; and (3) the type of bearing is not remontant (e.g., "Dorit" blooms perpetuously, during late fall and winter).
Fruit shape of "Dorit" is similar to the strawberry variety "Pajaro". The fruit is longer than broad, with primary, secondary and tertiary fruit possessing distinct shape (Table 2). The fruit is of medium firmness with an orange red color (Table 2).
The variety "Dorit" flowers several months earlier than known strawberry varieties. One of the closest known varieties would be "Karina" (Table 1) as well as the new varieties under co-pending U.S. patent application Ser. Nos. 07/735,969 ("Sharon"), 07/735,965 ("Shalom"), 07/735,967 ("Smadar"), and 07/735,970 ("Saaid"). Additionally early flowering results in early fruit production for "Dorit" and the four co-pending varieties (Table 3). Total Soluble Solids (TSS), percent acidity and aroma are presented in Table 4 by comparison to the varieties listed in Table 3.
