Description

Latin name of the genus and species: Ananas comosus.

Variety denomination: ‘Duranas’.

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 proprietary seedling of Ananas comosus with a different unnamed proprietary seedling of Ananas comosus. The new variety was discovered by the inventor, Chester Skotak Jr., a citizen of Costa Rica, in Ajauela, Costa Rica during June of 2005, in a group of seedlings resulting from the crossing.

Asexual reproduction of the new cultivar ‘Duranas’ was first performed in Costa Rica by vegetative cuttings, in January 2006. Propagation was subsequently performed by tissue culture in November 2006. ‘Duranas’ 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 ‘Duranas’ 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 ‘Duranas’ These characteristics in combination distinguish ‘Duranas’ as a new and distinct Ananas comosus cultivar:

    • 1. Compact, bushy plant shape.
    • 2. Small fruit.
    • 3. Suitability as an indoor pot plant.

Plants of the new cultivar ‘Duranas’ are similar to both parent varieties in some horticultural characteristics. However, ‘Duranas’ differs from both the seed and pollen parents in having a smaller fruit and shorter leaves.

COMMERCIAL COMPARISON

‘Duranas’ is best compared to the unpatented commercial variety Ananas comosus ‘Champaca.’ Plants of ‘Champaca’ are similar to plants of ‘Duranas’ in most horticultural characteristics, however, ‘Duranas’ has a more compact and bushy plant shape. ‘Duranas’ also has a lighter leaf color, shorter leaf and smaller fruit. Additionally the fruit of ‘Duranas’ is lighter in color than that of ‘Champaca.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘Duranas’ grown in a greenhouse. This plant is approximately 9 months old, shown in an 12 cm 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.

 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.

No artificial light, photoperiodic treatments or chemical treatments were given to the plants. Measurements and numerical values represent averages of typical plant types.
