Latest Sakata Ornamentals Europe A/S Patents:
Genus and species: Osteospermum hybrida.
Variety denomination: ‘Saksisgolye’.
BACKGROUND OF THE NEW PLANT‘Saksisgolye’ originated from a hybridization of proprietary hybrid Osteospermum breeding line ‘203005’ (unpatented) and commercial hybrid Osteospermum line ‘Sunny Amanda’ (U.S. Plant Pat. No. 16,522) in Aabyhoej, Denmark. The male parent, ‘Sunny Amanda’, has a pale-yellow flower color with terracotta-brown at the flower petal apices, medium flower size and brown disc florets. The female parent, ‘203005’ has a bright-yellow flower color, medium flower size and a compact and less branching plant growth habit.
In spring 2003, the two Osteospermum lines were crossed and 552 seeds were obtained. The seeds were sown and 442 plants were grown in pots for evaluation. Out of 442 F1 lines, plant number 197 was selected for its unique golden-yellow flower color with a dark center, medium size flowers and a compact plant growth habit.
In spring 2004, plant number 197 was vegetatively propagated with cuttings and re-evaluated in an open field and a greenhouse. Plant number 197 was given the code number ‘204057’.
In spring 2005, plants were evaluated again in pots and in an open field. The selection ‘204057’ was named ‘Saksisgolye’ and found to retain its distinctive characteristics through successive asexual propagations.
SUMMARY OF THE INVENTIONThe following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Salinas, Calif.
-
- 1. Golden-yellow flower color with dark center;
- 2. Medium flower size; and
- 3. Compact plant growth habit.
This new Osteospermum plant is illustrated by the accompanying photograph which shows the plant's overall plant habit including form, foliage and flowers. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.
The following detailed descriptions set forth the distinctive characteristics of ‘Saksisgolye’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. Data was collected on plants grown approximately six months from transplanting rooted cuttings into 5-inch pots under greenhouse conditions in Salinas, Calif. Color references are to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 4th edition.
DESCRIPTION OF THE NEW PLANT
- Classification:
-
- Family.—Compositae.
- Botanical.—Osteospermum hybrida.
-
- Parentage:
-
- Female parent.—An individual plant of Osteospermum line ‘203005’ (unpatented).
- Male parent.—An individual plant of Osteospermum line ‘Sunny Amanda’ (U.S. Plant Pat. No. 16,522).
-
- Growth:
-
- Time to produce a rooted cutting.—Cuttings will colonize a 2.5 cm diameter by 2.5 cm tall greenhouse tray cell with peat-based plant media in approximately four weeks. Cuttings are dipped in a normal dilution (1:9) of DIP 'N GROW root-inducing solution in water. The trays are misted hourly during rooting.
- Environmental conditions for plant growth.—Rooted cuttings are transplanted to pots with a 16 cm diameter, one plant per pot. Peat-based growing media is used. The pots are watered using a 150-200 ppm fertilizer solution containing 18% nitrogen, 8% phosphorus and 18% potassium. The soil is allowed to dry between waterings. During the first few weeks after transplanting, the plants have evening temperatures around 15°-18° C. for good root growth. When plants reach 7.5-10 cm in height they are pinched back to 5-6 leaves to promote branching. Spring and summer daytime high temperatures in Salinas, Calif., where the data was collected, range from 16°-25° C.
- Time to bloom from propagation.—Approximately four weeks after rooted vegetative cuttings are transferred to a 5-inch diameter pot. Flowering season is year-round in the United States. Vernalization is not required to induce flowering.

‘Saksisgolye’ is a distinct variety of Osteospermum owing to its golden-yellow flower color, medium flower size and compact plant growth habit. ‘Saksisgolye’ is distinguished from its parents primarily by ray floret color, disc floret color and plant growth habit as described in Table 1 (color references are to The Royal Horticultural Society Colour Chart, 4th edition):
‘Saksisgolye’ is most similar to the Osteospermum plant ‘Summertime Sunset’ (unpatented); however, there are differences as described in Table 2 (color references are to The Royal Horticultural Society Colour Chart, 4th edition):
