Description

Latin name of genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Ananas comosus (L.) Merr.

Variety denomination: The inventive variety of Ananas disclosed herein has been given the variety denomination ‘Duranas3’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2015/0609, filed Mar. 17, 2015, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Ananas comosus, ornamental pineapple. Ananas comosus is often planted for its tropical appearance and for its horticultural novelty. Its market class is PLT/156.

Parentage: The Ananas comosus variety ‘Duranas3’ is the result of a controlled pollination breeding program carried out in March of 2007 at a commercial greenhouse in Palmares, Costa Rica. ‘Duranas3’ is a progeny of said breeding program which resulted from the cross pollination of a Ananas comosus female breeding line, identified by the breeding code “03#12”, and a Ananas comosus male breeding line, identified by the breeding code “16#1”. Both of breeding lines were developed and owned by the inventor and were never commercially released. Progeny of said cross were observed for desired commercial characteristics and, in June of 2009, ‘Duranas3’ was selected for its compact inflorescence and dark red fruit.

Asexual Reproduction: ‘Duranas3’ was first asexually propagated by mericloning in June 2009 at a laboratory in Sleidinge, Belgium and has since been asexually propagated through eight additional generation. Through subsequent generations, the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The following characteristics have been repeatedly observed and represent the distinguishing characteristics of the new Ananas cultivar, ‘Duranas3’. These traits, in combination, distinguish ‘Duranas3’ as a new and distinct cultivar:

• • 1. ‘Duranas3’ exhibits a small, compact plant size; and
  • 2. ‘Duranas3’ exhibits greyed-purple to brown foliage; and
  • 3. ‘Duranas3’ exhibits strongly reflexed foliage; and
  • 4. ‘Duranas3’ exhibits dark red fruit.

FIG. 4 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical fruit of ‘Duranas3’.

DETAILED BOTANICAL DESCRIPTION

The following observations and measurements made in September of 2015 describe averages from a sample set of six specimens of 20 month-old ‘Duranas3’ plants grown in 12 cm nursery pots at a commercial greenhouse in Bergschenhoek, The Netherlands. Plants were grown under light maximum light levels of approximately 10,000 lux. Plants were maintained with a weekly fertigation program and regularly watered with overhead irrigation. No chemical pest measures were taken.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘Duranas3’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).

COMPARISONS WITH THE PARENTS

The breeding line parents of ‘Duranas3’ were never commercialized and are no longer in cultivation. Therefore, a comparison of ‘Duranas3’ with its parents is unavailable.

COMPARISON WITH THE MOST SIMILAR ANANAS CULTIVAR KNOWN TO THE INVENTOR

‘Duranas3’ is similar in many horticultural characteristics to the commercial cultivar Ananas ‘Duranas2’ (Community Plant Variety Rights application number 2012/2017). However ‘Duranas3’ differs from ‘Duranas2’ in the following characteristics:

• • 1. The fruit of ‘Duranas3’ exhibits a dark red general tonality, whereas the fruit of ‘Duranas2’ exhibits a yellow general tonality.
  • 2. ‘Duranas3’ exhibits a small and compact plant size, whereas ‘Duranas2’ exhibits a larger and less compact plant size.
