Bromeliad plant named ‘GUZ 227’

Abstract

A Bromeliad hybrid comprising an improvement over its parent, Guzmania ‘Irene’. The foliage is denser and more compact than that of ‘Irene’, and the leaves are darker, thicker and wider. The plant is a tetraploid, and is faster growing than ‘Irene’, reaching marketability in 10-12 months. The primary bracts are wider and closer together making the spike fuller and more compact. The bract color is darker and clearer than that of ‘Irene’.

Description

BACKGROUND OF THE INVENTION

This application relates to a newly developed interspecific hybrid Guzmania plant resulting from a planned breeding program that is conducted on an ongoing basis. The objects of the breeding program include the crossing of selected parent plants from the numerous, compatible species within the genus, to obtain plants with novel and attractive phenotypes, coloration, and flowering forms. Other important selection factors may include ultimate plant size and shape, disease resistance, tolerance to different soil and growing conditions and vigor.

Additional objects of the breeding program are to produce plants of the Bromeliaceae family which will be attractive to the consumer; which will develop reasonably rapidly under controlled conditions; and, retain for a long term, highly attractive and bright inflorescence; i.e., bract coloration, after being induced into the flowering stage. It is a specific object to provide a low maintenance plant which will be a long term decorative appointment offering an exotic color splash in the home of a buyer, or to serve as a substitute for flowering plants which have a shorter flowering duration in, for example, indoor plant and flower scapes. Finally, it is an object to develop plants which may be easily and efficiently multiplied by state-of-the-art tissue culture methods while continuing the distinctive characteristics of the plants through progressive clonal generations.

The plant was a sport of Guzmania ‘Irene’ (unpatented) which is the progeny resulting from the cross of Guzmania lingulata ‘Equador’ (unpatented)×Guzmania wittmackii, ‘Pink Equador’ (unpatented). This particular sport was about 1¼ years old when discovered by me growing at a nursery under my control in Pynacker, Holland. With the recognition that this sport satisfied the objects of the breeding program, the sport was isolated and set aside for further observation and testing. The resulting selection has been assigned the designation ‘GUZ 227’ for purposes of identification. This plant has been reproduced by tissue culture at Evergem Belgium, and the clonal specimens resulting therefrom have been determined to be identical to the original selection in all distinguishing characteristics. The distinctive attributes of this plant will be revealed in the Summary of the Invention and the Botanical Description to follow.

SUMMARY OF THE INVENTION

The attributes of the plant ‘GUZ 227’ which distinguish it from the other similar Guzmania hybrids are described as follows:

This hybrid represents a marked improvement over the Guzmania ‘Irene’. The foliage of ‘GUZ 227’ is denser and more compact than ‘Irene’ with darker, wider and thicker leaves. The plant grows faster than ‘Irene’ with a broader overall width. The primary bracts are closer together making the floral spike more compact. The upper primary bracts are more horizontal, giving the spike a more symmetrical appearance. The individual bracts are broader giving the floral spike a fuller appearance. The color of the bract is darker and clearer than the bract of Guzmania ‘Irene’ of which it is derived. ‘GUZ 227’ grows more rapidly than Guzmania ‘Irene’, growing from liner to marketability in 10-12 months.

This hybrid holds its color well for 3 to 4 months under interior lighting conditions.

No unusual susceptibility to diseases of Guzmania has been noted.

BRIEF DESCRIPTION OF THE DRAWING

The single color photograph of the drawing depicts a mature 1¼ years old specimen of the plant in mid to late flowering stage. Illustrated are the mature leaves, scape bracts and primary bracts. The color definitions in the specification have been taken from The R.H.S Colour Chart of The Royal Horticultural Society. The colors depicted are believed to be of a high level of color fidelity and are believed to be as close to the actual coloration of the plant as possible in a photographic illustration of this quality. However, due to factors such as light reflectance, cultural conditions and horticultural practices, the coloration of this plant should be understood to be approximate. For example, the bract color might slightly fade if the plant is subjected to bright light and the leaf color may vary depending on the composition and the concentration of fertilizer which may be applied to the plant.
