Abstract
‘MAROBA 3’ is a new and distinctive variety of Dieffenbachia plant which is characterized by a compact, upright growth habit with an abundance of dark green, glossy foliage borne on dark green petioles, unique foliage variegation with a moderate amount light greyed-green blotches along the secondary leaf veins with sparse blotches following a similar pattern in the interveinal areas, and the stability of all characteristics from generation to generation.
Description
Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Dieffenbachia Schott.
Variety denomination: The inventive variety of Dieffenbachia disclosed herein has been given the variety denomination ‘MAROBA 3’.
This application claims priority to the Community Plant Variety Rights application number 2019/3233, filed Nov. 29, 2019, which is herein incorporated by reference.
Parentage: ‘MAROBA 3’ originated as a naturally-occurring, whole plant mutation of Dieffenbachia ‘MAROBA’ (U.S. Plant Pat. No. 9,220). In August of 2018 the inventor discovered the mutation at a commercial greenhouse in Bleiswijk, the Netherlands, growing amongst a crop of Dieffenbachia ‘MAROBA’. The mutation was noted for its freely-branching, compact growth habit, and unique foliage variegation and was subsequently isolated for further evaluation in order to confirm the distinctness and stability of the characteristics first observed. Upon confirmation of distinctness and stability, the new Dieffenbachia plant was selected for commercialization and given the name ‘MAROBA 3’.
Asexual Reproduction: Asexual reproduction of ‘MAROBA 3’, by way of softwood stem cuttings, was first performed in the November of 2020 at a commercial greenhouse in Bleiswijk, the Netherlands. Five successive generations so produced have shown that the unique features of the instant cultivar are stable and reproduced true to type.
The cultivar ‘MAROBA 3’ has not been observed under all possible environmental conditions and the phenotype may vary somewhat with variations in the instant environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following characteristics have been repeatedly observed and represent the distinguishing characteristics of the new Dieffenbachia cultivar ‘MAROBA 3’. These traits, in combination, distinguish ‘MAROBA 3’ as a new and distinct cultivar.
-
- 1. Dieffenbachia ‘MAROBA 3’ exhibits a compact, upright growth habit with an abundance of foliage; and
- 2. Dieffenbachia ‘MAROBA 3’ exhibits an abundance of dark green, glossy foliage borne on dark green petioles; and
- 3. Dieffenbachia ‘MAROBA 3’ exhibits a unique foliage variegation pattern consisting of a moderate amount of irregular light greyed-green blotches that generally follow the secondary leaf veins with sparse blotches following a similar pattern in the interveinal areas.
Generally appearing as a darker shade of green, relative to ‘REEVA’; moderately blotched with a mixture of yellow-green and greyed-green along the secondary veins which generally appears nearer to a light a very light greyed-green coloration; interveinal areas are slightly blotched yellow-green.
The following is a detailed botanical description of a new and distinct variety of Dieffenbachia known as ‘MAROBA 3’, based upon observations of plants, approximately 35 weeks old from a rooted cutting, grown in 12 cm nursery container in a climate-controlled greenhouse in Bleiswijk, the Netherlands. Observation data was recorded in November of 2020. Plants were produced using conventional greenhouse production protocols for Dieffenbachia which consisted of regular 2.2 to 3.0 EC fertilizer applications and regular irrigation. No pest or disease control measures were utilized in production. Plants were produced under shade and no photoperiodic treatments or artificial light was given to the plants.
Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘MAROBA 3’ 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 measurements 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 edition.
