Abstract

A new and distinct cultivar of Guzmania plant named ‘Bel-Air’, characterized by its compact, upright and outwardly arching growth habit; dark green-colored foliage; inflorescences held upright and above foliage on strong scapes; inflorescences with closely-spaced dark purple-colored primary bracts that are tipped with yellow; and long-lasting inflorescences that maintain good coloration for about four months in the interiorscape and about 20 to 30 weeks in the greenhouse.

Description

Botanical designation: Guzmania conifera.

Cultivar denomination: ‘BEL-AIR’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Guzmania, botanically known as Guzmania conifera and hereinafter referred to by the name ‘Bel-Air’.

The new Guzmania is a product of a planned breeding program conducted by the Inventor in Sao Paulo, Brazil. The objective of the breeding program is to create new Guzmania varieties having unique flower colors and enhanced postproduction longevity.

The new Guzmania originated from a cross-pollination made by the Inventor in January, 1999, in Sao Paulo, Brazil, of a proprietary section of Guzmania conifera identified as code number L#32, not patented, as the female, or seed, parent with a proprietary selection of Guzmania conifera identified as code number B#4, not patented, as the male, or pollen, parent. The new Guzmania was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Sao Paulo, Brazil, in September, 2003.

Asexual reproduction of the new Guzmania by tissue culture in a controlled environment in Homestead, Fla., has shown that the unique features of this new Guzmania are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Bel-Air has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Bel-Air’. These characteristics in combination distinguish ‘Bel-Air’ as a new and distinct cultivar of Guzmania:

- 1. Compact, upright and outwardly arching growth habit.
- 2. Dark green-colored foliage.
- 3. Inflorescences held upright and above foliage on strong scapes.
- 4. Inflorescences with closely-spaced dark purple-colored primary (flower) bracts that are tipped with yellow.
- 5. Long-lasting inflorescences that maintain good coloration for about four months in the interiorscape and about 20 to 30 weeks in the greenhouse.

Plants of the new Guzmania can be compared to plants of the female parent selection in the following characteristics:

- 1. Plants of the new Guzmania are more compact than plants of the female parent selection.
- 2. Leaves of plants of the new Guzmania are darker green in color than leaves of plants of the female parent selection.
- 3. Plants of the new Guzmania and female parent selection differ in primary bract color as plants of the female parent selection have red-colored primary bracts.

Plants of the new Guzmania can be compared to plants of the male parent selection in the following characteristics:

- 1. Plants of the new Guzmania are more compact than plants of the male parent selection.
- 2. Leaves of plants of the new Guzmania are darker green in color than leaves of plants of the male parent selection.
- 3. Plants of the new Guzmania and male parent selection differ in primary bract color as plants of the male parent selection have red and yellow-colored primary bracts.

Plants of the new Guzmania can be compared to plants of the Guzmania cultivar Olympic, disclosed in U.S. Plant Pat. No. 10,787. In side-by-side comparisons conducted in Homestead, Fla., plants of the new Guzmania and the cultivar Olympic differed in the following characteristics:

- 1. Leaves of plants of the new Guzmania were darker in color than leaves of plants of the cultivar Olympic.
- 2. Plants of the new Guzmania and the cultivar Olympic differed in primary bract color as plants of the cultivar Olympic had yellow and orange-colored flowers bracts.

Plants of the new Guzmania can be compared to plants of the Guzmania cultivar Torch, disclosed in U.S. Plant Pat. No. 9,426. In side-by-side comparisons conducted in Homestead, Fla., plants of the new Guzmania and the cultivar Torch differed in the following characteristics:

- 1. Plants of the new Guzmania were more compact than plants of the cultivar Torch.
- 2. Plants of the new Guzmania and the cultivar Torch differed in primary bract color as plants of the cultivar Torch had orange and yellow-colored flowers bracts.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrated the overall appearance of the new Guzmania, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Guzmania.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Bel-Air’ grown in a container.

The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Bel-Air’.

DETAILED BOTANICAL DESCRIPTION

All color references are measured against The Royal Horticultural Society Colour Chart, 1995 Edition. Colors and numerical measurements are approximate as plant growth and development depends on environmental conditions and cultural practices such as light level and temperature, among others, without, however any variance in genotype.

Plants used for the aforementioned photographs and the following description were about 14 months old and grown in 15-cm containers in Homestead, Fla., during the spring in a polyethylene-covered greenhouse with day temperatures averaging 28° C., night temperatures averaging 20° C. and light levels about 1,600 foot-candles.
