Abstract

A new cultivar of Guzmania named `Rumba` characterized by a plant form that is funnel-form rosette; plant height of approximately 50 cm; linear-lanceolate leaves measuring 25-40 cm in length and 3-4 cm in width; leaf color upperside of R.H.S. 147A and underside of R.H.S 137A; primary bract color of R.H.S. 34A to R.H.S. 169A and top bract color of R.H.S. 17A.

Description

The present invention relates to a new and distinct cultivar of Guzmania that is an interspecific hybrid, hereinafter referred to by the cultivar name `Rumba`.
BACKGROUND OF THE INVENTION
Guzmania are predominantly epiphytic with a few terrestrial species and are native to the tropics. For the most part species vary in diameter from 7 or 8 inches to 3 to 4 feet and have rosettes of glossy, smooth edged leaves.
Floral bracts of Guzmania frequently have brilliant colors and may last for many months. The range of colors for Guzmania is generally from yellow through orange but may also include flame red and red-purple. White or yellow, tubular, three petalled flowers may also appear on a stem or within the leaf rosette but are usually short lived.
Guzmania may be advantageously grown as pot plants for greenhouse or home use. Desirably the plants are shaded from direct sunlight and during the spring to autumn period the central vase-like part of the leaf rosette is desirably filled with water.
Guzmania is native to tropical America. Leaves of Guzmania are usually formed as basal rosettes which are stiff and entire and in several vertical ranks. Guzmania have terminal spikes or panicles which are often bracted with petals united in a tube about as long as the calyx. The ovary is superior and the seeds plumose.
Asexual propagation of Guzmania is frequently done through the use of tissue culture practices. Propagation can also be from off-shoots produced by the plant which may then be rooted. The resulting plantlets are detached from the mother plant and may be potted up in a suitable growing mixture.
Methods for cultivation and crossing of Guzmania are well known. For a detailed discussion, reference is made to the following publications, which are incorporated herein by reference. Benzing, David H., THE BIOLOGY OF THE BROMELIADS, mad River Press, Inc., Eureka (1980); Zimmer, Karl, BROMELIEN, Verlag Paul Parey, Berlin (1986); and Rauh, Werner, BROMELIEN, Verlag Eugen Ulmer, Stuttgart (1981).
The new cultivar `Rumba` is a product of a planned breeding program and was originated by the inventors from a cross made during such a program in Assendelft, The Netherlands, in 1987. The male or pollen parent was a proprietary selection of Guzmania wittmackii minor identified by Code No. 8705260. The female or seed parent was a proprietary selection of Guzmania lingulata minor identified by Code No. 8705211.
The selection comprising the new variety was chosen from among progeny of the above cross following commencement of flowering in 1989 in Assendelft, The Netherland. The selection was first asexually propagated through off-shoots by, or under the supervision of, the inventors in Assendelft, with subsequent asexual reproduction through tissue culture. Continuous asexual propagation has demonstrated that the combination of characteristics as herein disclosed for the new cultivar `Ruma`, as observed in Assendelft, the Netherlands, are firmly fixed and are retained through successive generations of asexual reproduction.
`Rumba` has not been tested under all available environmental conditions. The phenotype may vary with variations in environmental conditions such as temperature, light intensity, frequency of fertilization, composition of fertilizer, acetylene treatment, day length and humidity without, however, any change in the genotype of the new cultivar. In comparision to the cultivar `Samba`, the cultivar, `Rumba` produces an orange inflorescence.
BRIEF SUMMARY OF THE INVENTION
`Rumba` is particularly characterized by the following characteristics:
1. Plant form that is a funnel shaped rosette,
2. Plant height of approximately 50 cm,
3. Linear lanceolate leaves measuring 25-40 cm in length and 3-4 cm in width,
4. Leaf color upper side of R.H.S 147A and underside of R.H.S. 137A,
5. Primary bract color between R.H.S. 34A and R.H.S. 169A,
6. Top bract color of R.H.S. 17A.
BRIEF DESCRIPTION OF THE DRAWING
In the accompanying color photographic drawing, sheet 1 is a side view of a specimen of `Rumba` showing the primary and top bracts.
DETAILED BOTANICAL DESCRIPTION
The following traits have been repeatedly observed and in combination distinguish `Rumba` as a new and distinct cultivar. These observations, measurements and descriptions were taken for `Rumba` plants grown under the following greenhouse conditions in Assendelft, The Netherlands. The minimum day and night temperature was 20° and 18° C., respectively. The ventilation temperature was 24° C. and the maximum light intensity was 18000 Lux. Fertilizer concentration was 0.5 to 1 EC comprising N:P:K in the ratio of 1:0.25 to 0.5:2 to 3. In addition, 3% of the total amount of fertilizer was MgSO4.
Frequency of fertilization varied depending on time of year and ranged from once per week to once per month. Fertilization was more frequent during the spring and smmer months. Following fertilization, the plants were rinsed with sufficient clean water to remove residual fertilizer from the leaves.
With regard to induction of flowering, acetylene gas is allowed to bubble through 100 L of cool water for 30 min at a pressure of 0.5 bar. Whole plants are then sprayed with the acetylene solution making certain that the cup (vase) is filled. Spraying is done in the morning because the plants need light after this treatment and the plants are not watered again for at least two days. The plants are treated again, following this same protocol, one week later. Plants should not be fertilized for two to three weeks following treatment with acetylene because it is likely the flowers will not from and the bracts will remain green.
