Abstract
A new and distinct Spathiphyllum cultivar named ‘SP6531’ is disclosed, characterized by dark green foliage, clear white inflorescence and distinctive busy basal growth. The new variety produces a high quantity of spathes all at once, and flowers at 11 weeks from GA3 induction. The new variety is a Spathiphyllum, typically produced as an indoor ornamental plant.
Description
Latin name of the genus and species: Spathiphyllum hybrid.
Variety denomination: ‘SP6531’.
The new cultivar is a product of a planned breeding program. The objective of the breeding program was to develop new Spathiphyllum varieties suitable for commercial pot production. The new variety originated from a cross pollination of two unnamed, proprietary, parents. The inventor has no record of the exact parents involved in the cross. The crossing was made during April 2005.
The new variety was discovered by the inventor, Daniel Cornelis, a citizen of Belgium, in February 2006 in a group of seedlings resulting from the crossing. The new cultivar was found in a commercial green house belonging to the inventor in Melsem-Merelbeke, Belgium.
Asexual reproduction of the new cultivar ‘SP6531’ was first performed at a commercial laboratory in Belgium by tissue culture in April of 2007. Subsequent propagation by tissue culture has shown that the unique features of this cultivar are stable and reproduced true to type.
The cultivar ‘SP6531’ 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 ‘SP6531.’ These characteristics in combination distinguish ‘SP6531’ as a new and distinct Spathiphyllum cultivar:
-
- 1. Dark green foliage.
- 2. Clear white inflorescence.
- 3. Distinctive bushy base due to a high number of shoots arising from the base of the plant.
- 4. High quantity of spathes produced at once.
- 5. Time to flowering 11 weeks from GA3 induction.
The inventor is unable to compare the new variety to the parent, as he has no record of the actual parents used for the cross.
‘SP6531’ can be compared to the commercial variety Spathiphyllum ‘Mara’ U.S. Plant Pat. No. 16,422. Plants of ‘Mara’ are similar to plants of ‘SP6531’ in most horticultural characteristics, however, ‘SP6531’ has darker and smaller leaves than ‘Mara.’ Additionally ‘SP6531’ produces many more shoots and has a smaller inflorescence than ‘Mara.’
‘SP6531’ can also be compared to compared to the commercial variety Spathiphyllum ‘Alfa CD’ U.S. Plant Pat. No. 10,823. Plants of ‘Alfa CD’ are similar to plants of ‘SP6531’ in most horticultural characteristics, however, ‘SP6531’ has much darker leaves than ‘Alfa CD.’ Additionally ‘SP6531’ produces many more basal shoots per plant than ‘Alfa CD.’
The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘SP6531’ grown in a greenhouse in Apopka, Fla. This plant is approximately 9 months old, shown in a 6 inch pot.
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.
In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘SP6531’ plants grown in a climate controlled greenhouse in Apopka, Fla., USA. Temperatures ranged from 20° C. to 25° C. at night to 25° C. to 32° C. during the day. No artificial light, photoperiodic treatments were given to the plants. Plants were treated with Giberellic Acid at 200 ppm, to induce spathe production in approximately 11 weeks. Plants were grown in approximately 70% shade. Measurements and numerical values represent averages of typical plant types.
