ABSTRACT:
FIELD OF INVENTION
The present invention relates to a new and distinct cultivar of Guzmania that is a hybrid, hereinafter referred to by the cultivar name ‘Copito’. The present invention relates to seeds which are Guzmania cultivar ‘Copito’, as well as plants and plant parts produced from these seeds which have all the morphological and physiological characteristics of the Guzmania cultivar ‘Copito’. The present invention also relates to methods for producing these seeds and plants. Furthermore, the present invention relates to a method of producing progeny Guzmania plants by crossing Guzmania cultivar ‘Copito’, as the male or female parent, with another Guzmania plant and selecting progeny.
BACKGROUND OF THE INVENTION
Guzmania is predominantly epiphytic with a few terrestrial species and is native to the tropics. For the most part, species vary in diameter from 7 or 8 inches to 3 or 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. Typically, the plants are shaded from direct sunlight. During the spring to autumn period, the central vase-like part of the leaf rosette is normally 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 plants 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 offshoots which can be detached from the mother plant and grown in an appropriate soil or bark 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.,

A Guzmnania inbred is produced by brother/sister crossing over several generations to produce a genetically homozygous plant selection. A hybrid cultivar is produced by crossing two genetically distinct inbred lines, collecting seeds produced by the cross, and germinating seeds so-produced to make hybrid plants. The hybrid seeds and plants produced by this method are uniform with respect to their morphological and physiological characteristics.
A need exists for a greater variety of Guzrnania cultivars with attractive ornamental features. Additionally, a need exists for additional Guzmania hybrid cultivars that can be easily propagated by seed.
SUMMARY OF THE INVENTION
These and other objectives have been achieved in accordance with the present invention which provides a new cultivar ‘Copito’ that is a product of a planned breeding program undertaken by the inventors in Assendelft, The Netherlands, in 1994. The male or pollen parent was a selection of Guzmania lingulata minor identified by Code No. 94861137. The female or seed parent was a selection of Guzmania lingulata minor identified by Code No. 94861032.
Both parents have a sufficient degree of homozygosity such that the progeny of the cross are genetically and phenotypically uniform. The cultivar ‘Copito’ therefore can be produced by sexual reproduction by crossing 94861137×94861032 to produce a population of progeny plants, each of which has the combination of characteristics as herein disclosed for the new cultivar. Seeds, which are cultivar ‘Copito’, are produced by crossing 94861137×94861032 and have been deposited with the American Type Culture Collection, 10801 University Boulevard, Manassas, Va. 20110-2209, and accorded Deposit Accession No. PTA-3263. 2500 seeds were deposited with the ATCC on Apr. 9, 2001.
The cultivar ‘Copito’ can also be produced by asexually reproducing progeny from the cross of 94861137×94861032 because the combination of characteristics as herein disclosed for the new cultivar ‘Copito’ are firmly fixed and are retained through successive generations of asexual reproduction.
OBJECTS OF THE INVENTION
This invention relates to seeds which produce Guzmania cultivar ‘Copito’.
This invention also relates to Guzmnania plants, and parts thereof, having all the physiological and morphological characteristics of Guzmania cultivar ‘Copito’. This invention relates to a plant produced from seeds which are Guzmania cultivar ‘Copito’. This invention also relates to plant parts, such as pollen, seeds or inflorescence produced by Guzmania cultivar ‘Copito’.
This invention relates to a method of producing seeds which are Guzmania cultivar ‘Copito’, by crossing Guzmania lingulata minor selection 94861032 as the female parent with Guzmania lingulata minor selection 94861137 as the male parent and the reciprocate cross with 94861032 as the male parent and 94861137 as the female parent and harvesting seeds produced from said crosses.
This invention also relates to a method of producing plants having all the physiological and morphological characteristics of the Guzmania cultivar ‘Copito’ comprising the steps of (a) crossing Guzmania lingulata minor selection 94861032 as the female parent with Guzmania lingulata minor selection 94861137 as the male parent; (b) harvesting seeds produced from said cross; and (c) producing plants from said harvested seeds.
The invention also relates to producing progeny plants from the cross of Guzmania cultivar ‘Copito’, as the male or female parent, with another Guzmania plant, and selecting progeny plants for this cross.
