Abstract

A new and distinct cultivar of Mandevilla plant named ‘DIP 79’, characterized by its upright and vining plant habit; vibrant red-colored flowers; and year-round flowering period.

Description

Botanical designation: Mandevilla splendens.

Cultivar denomination: ‘DIP 79’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla, botanically known as Mandevilla splendens and hereinafter referred to by the name ‘DIP 79’.

The new Mandevilla is a product of a planned breeding program conducted by the Inventors in Sebring, Fla. The objective of the breeding program is to create new Mandevilla cultivars with dense foliage and red-colored flowers.

The new Mandevilla originated from an open-pollination during May, 2003 in Sebring, Fla. of the Mandevilla splendens cultivar Red Riding Hood, not patented, as the female, or seed parent with an unknown selection of Mandevilla splendens as the male, or pollen, parent. The cultivar DIP 79 was discovered and selected by the Inventors as a flowering plant from within the progeny of the stated open-pollination in a controlled environment in Sebring, Fla. May, 2004.

Asexual reproduction of the new cultivar by cuttings in Sebring, Fla. since March, 2005, has shown that the unique features of this new Mandevilla are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar DIP 79 have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature 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 ‘DIP 79’. These characteristics in combination distinguish ‘DIP 79’ as a new and distinct cultivar:

- 1. Upright and vining plant habit.
- 2. Vibrant red-colored flowers.
- 3. Year-round flowering period.

Plants of the new Mandevilla differ primarily from plants of the female parent, the cultivar Red Riding Hood, in the following characteristics:

- 1. Plants of the new Mandevilla are larger and more vigorous and vining than plants of the cultivar Red Riding Hood.
- 2. Plants of the new Mandevilla are more freely branching than plants of the cultivar Red Riding Hood.
- 3. Plants of the new Mandevilla are more freely flowering than plants of the cultivar Red Riding Hood.
- 4. Plants of the new Mandevilla have darker red-colored flowers than plants of the cultivar Red Riding Hood.

Plants of the new Mandevilla can also be compared to plants of the Mandevilla cultivar Sunmandecrim, disclosed in U.S. Plant Pat. No. 15,539. In side-by-side comparisons conducted in Sebring, Fla., plants of the new Mandevilla differed from plants of the cultivar Sunmandecrim in the following characteristics:

- 1. Plants of the new Mandevilla were more strongly vining than plants of the cultivar Sunmandecrim.
- 2. Plants of the new Mandevilla were larger and more vigorous than plants of the cultivar Sunmandecrim.
- 3. Plants of the new Mandevilla had larger and lighter green-colored leaves than plants of the cultivar Sunmandecrim.
- 4. Plants of the new Mandevilla flowered earlier and more freely than plants of the cultivar Sunmandecrim.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Mandevilla.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘DIP 79’ grown in a container.

The photograph on the second sheet is a close-up view of typical plants of ‘DIP 79’, ‘Red Riding Hood’ and ‘Sunmandecrim’ (left to right).

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the aforementioned photographs and following description were grown under conditions which closely approximate commercial production conditions during the autumn and winter in a polyethylene-covered greenhouse in Sebring, Fla. for about 13 weeks in 25-cm containers. Plants were pinched one time about two weeks after planting. During the production of the plants, day temperatures ranged from 21° C. to 38° C. and night temperatures averaged 24° C.
