Abstract
A new miniature rose plant which was abundant, yellow colored flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year round production in commercial glass houses as a flowering pot plant. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.
Description
Botanical designation: Rosa hybrida.
Variety denomination: ‘PACfifty’.
The present invention constitutes a new and distinct variety of miniature rose plant, which was developed by artificially pollinating an unnamed seedling (not patented) with an unnamed seedling (not patented). The two parents were crossed in the summer of 2004 and the resulting seed was sown in December 2004, in a controlled glasshouse environment. Out of these seedlings one seedling was selected, as the new variety and named ‘PACfifty’. The new rose may be distinguished from its seed parent, an unnamed seedling, by the following combination of characteristics:
-
- 1. ‘PACfifty’ has medium double flowers, while the unnamed seedling has medium single flowers.
- 2. ‘PACfifty’ has yellow colored petals, while the unnamed seedling has orange petals.
The new variety may be distinguished from its pollen parent, an unnamed seedling created by the same inventor, by the following combination of characteristics:
-
- 1. ‘PACfifty’, has medium double flowers, while the unnamed seedling has medium double flowers.
- 2. ‘PACfifty’ yellow colored petals, while the unnamed seedling has dark yellow petals.
Initial asexual reproduction of ‘PACfifty’ by cuttings was first done in Santa Barbara, Calif., USA. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘PACfifty’ are true to type and are transmitted one generation to the next. ‘PACfifty’ is a low and compact miniature rose with good vigor. The objective of the hybridization of this rose variety for commercial greenhouse culture was to create a new and distinct variety with:
-
- 1. Uniform and abundant flowers with good keepability;
- 2. Attractive long lasting foliage and compact growth;
- 3. Year round flowering under glasshouse conditions;
- 4. Suitability for production from softwood cuttings in pots;
- 5. Durable flowers and foliage which make the variety suitable for distribution in the floral industry.
This combination of qualities was not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘PACfifty’ from all other varieties of which I am aware.
The seeds from hybridization were planted in a controlled environment and evaluations were conducted on the resulting plants. ‘PACfifty’ was selected by, Daniel Jauchen, in his development program in Santa Barbara, Calif., USA.
The accompanying color illustrations show as true as is reasonably to obtain in color photographs of this type, the typical characteristics of the buds, flowers, leaves, stems of ‘PACfifty’. Specifically illustrated in the drawings:
1: Young shoot.
2: Bud before opening the sepals.
3: Bud at the stage of opening the sepals.
4: Bud at the stage of opening the petals.
5: Flower during course of opening.
6: Open flower—plan view—obverse.
7: Open flower—plan view—reverse.
8: Fully open flower—plan view—observe.
9: Fully open flower—plan view—reverse.
10: Receptacle showing stamens and pistils.
11: Receptacle showing pistils (stamens and sepals removed).
12: Flower petals, detached—inner surface.
13: Flower petals, detached—outer surface.
14: Bare stem exhibiting thorns and flower attachment.
15: Three leaflets upper side.
16: Three leaflets reverse side.
17: Five leaflets upper side.
18: Five leaflets reverse side.
The following is a detailed description of the Miniature Rose: Rosa hybrida ‘PACfifty’.
The following observations, measurements, values and comparisons describe plants grown in glass houses in Santa Barbara, Calif., USA.
The age of the observed plants were 3 months after propagation by cuttings, and produced as flowering pot plants in container of 10 centimeter in diameter. Environmental conditions in the cultivation area for the observed plants, has been temperatures from 64 to 78 degrees Fahrenheit, and 10 to 20 hours day length with assimilation light. Light levels from 600 foot candle to 6000 foot candle. The relative humidity has been ranging from 50 to 85%.
Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 1995, except where common terms of color are used. For a comparison, the nearest existing rose variety is ‘POULsun’, a rose variety described and illustrated in U.S. Plant Pat. No. PP 9,716.
