Abstract

A new and distinct Guzmania hybrid cultivar named ‘DURAMAR’ is disclosed, characterized by unique bract coloration, shiny bracts and a broad overall inflorescence. The new variety is a Guzmania, and is normally used as an ornamental plant.

Description

Latin name of the genus and species: Guzmania wittmackii×lingulata.

Variety denomination: ‘DURAMAR’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The new variety originated from a cross pollination of an unnamed, unpatented, proprietary seedling Guzmania wittmackii with an unnamed, unpatented, proprietary seedling Guzmania lingulata. The new variety was discovered by the inventor, Chester Skotak Jr., a citizen of Costa Rica, in Ajauela, Costa Rica during 2004, in a group of seedlings resulting from the crossing.

Asexual reproduction of the new cultivar ‘Duramar’ was first performed in Belgium by tissue culture, in March 2005. ‘Duramar’ has since produced several generations by tissue culture and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘DURAMAR’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘DURAMAR.’ These characteristics in combination distinguish ‘DURAMAR’ as a new and distinct Guzmania hybrid cultivar:

- 1. Unique bract coloration.
- 2. Shiny bracts.
- 3. Broad overall inflorescence.

PARENT COMPARISON

Plants of the new cultivar ‘DURAMAR’ are similar to plants of the seed parent variety, an unnamed, unpatented, proprietary seedling of Guzmania wittmackii, in most horticultural characteristics. However, plants of the new cultivar ‘DURAMAR’ produce purple-tipped bracts, whereas the seed parent produces bracts only colored yellow and orange. Additionally, the new variety has a wider flower than the seed parent, and shinier bracts than the seed parent.

Plants of the new cultivar ‘DURAMAR’ are similar to plants of the pollen parent variety, an unnamed, unpatented, proprietary seedling of Guzmania lingulata, in most horticultural characteristics. However, plants of the new cultivar ‘DURAMAR’ are taller and do not have a white upper bract coloration found on the pollen parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DURAMAR’ are similar to plants of the unpatented commercial variety, Guzmania hybrid ‘Marjan’ in most horticultural characteristics. However, plants of the new cultivar ‘DURAMAR’ produce purple tipped bracts, not found on ‘Marjan’ and ‘DURAMAR’ produces shinier bracts than ‘Marjan.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DURAMAR’ grown in a greenhouse. The pot size is a commercial 11 cm container. The plant shown is approximately 18 months old. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘DURAMAR’ plants grown in a commercial controlled greenhouse in Evergem, the Netherlands. Temperatures ranged from 20° C. to 28° C. night and day. No artificial light, photoperiodic treatments or chemical treatments were given to the plants. Measurements and numerical values represent averages of typical plant types.
