Latest Altria Lab-Plants LLC Patents:
Latin name of the genus and species: Guzmania hybrid.
Variety denomination: ‘Aureus’.
BACKGROUND OF THE INVENTIONThe new cultivar is a product of a planned breeding program. The new variety originated from a cross pollination of the seed parent, an unnamed proprietary variety of Guzmania hybrid with the pollen parent Guzmania lingulata, directed by the inventor in October of 2004.
‘Aureus’ was discovered by the inventor, Rolf Kurt Zornig, in October 2006 in Campinas, Brazil in a group of seedlings resulting from the 2004 crossing.
Asexual reproduction of the new cultivar ‘Aureus’ was first performed in Campinas, Brazil by tissue culture in July 2007. ‘Aureus’ has since produced several generations by micro-propagation and has shown that the unique features of this cultivar are stable and reproduced true to type.
SUMMARY OF THE INVENTIONThe cultivar ‘Aureus’ 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 ‘Aureus’ These characteristics in combination distinguish ‘Aureus’ as a new and distinct Guzmania cultivar:
-
- 1. Compact plant shape.
- 2. Long inflorescence.
- 3. Yellow inflorescence color.
- 4. Suitability as an indoor pot plant.
Plants of the new cultivar ‘Aureus’ are similar to both parent varieties in most horticultural characterisitics. However, ‘Aureus’ differs from both the seed and pollen parents in having a more compact plant shape and longer inflorescence.
COMMERCIAL COMPARISON‘Aureus’ can be compared to the patented commercial variety Guzmania ‘Deplakar,’ U.S. Plant Pat. No. 13,754. Plants of ‘Deplakar’ are similar to plants of ‘Aureus’ in most horticultural characteristics, however, ‘Aureus’ has shorter, narrow foliage, scape and terminal bracts more yellow than orange-yellow in color.
‘Aureus’ can be compared to the unpatented commercial variety Guzmania ‘Marjan’ Plants of ‘Marjan’ are similar to plants of ‘Aureus’ in most horticultural characteristics, however, ‘Aureus’ has a wider inflorescence, and a shorter overall plant height than ‘Marjan’.
