USPP18084P2 - Nemesia plant named ‘Intraired’ - Google Patents

Abstract

A new and distinct cultivar of Nemesia plant named ‘Intraired’, characterized by its upright, outwardly spreading to trailing plant habit; freely branching habit; dense and bushy appearance; early flowering habit; numerous large dark red-colored flowers; and long flowering period.

Description

Botanical designation: Nemesia hybrid.

Cultivar denomination: ‘Intraired’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesia plant, botanically known as Nemesia hybrid and referred to by the name ‘Intraired’.

The new Nemesia is a product of a planned breeding program conducted by the Inventors in Gensingen, Germany. The objective of the program is to create new strong Nemesia cultivars with numerous flowers and unique flower colors.

The new Nemesia originated from a cross-pollination made by the Inventors of an unnamed Nemesia strumosa selection, not patented, as the female, or seed, parent with an unnamed Nemesia fructicans selection, not patented during the summer of 2001. The cultivar Intraired was discovered and selected by the Inventors as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Gensingen, Germany during the spring of 2002.

Asexual reproduction of the new Nemesia by terminal cuttings in a controlled environment in Gensingen, Germany since June, 2002, has shown that the unique features of this new Nemesia are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The new Nemesia has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following characteristics have been repeatedly observed and are determined to be basic characteristics of ‘Intraired’ and distinguish ‘Intraired’ as a new and distinct cultivar:

• • 1. Upright, outwardly spreading to trailing plant habit.
  • 2. Freely branching habit; dense and bushy appearance.
  • 3. Early flowering habit.
  • 4. Numerous large dark red-colored flowers.
  • 5. Long flowering period.

Plants of the new Nemesia differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Nemesia are more outwardly spreading than and not as upright as plants of the female parent selection.
  • 2. Plants of the new Nemesia flower for a longer period of time than plants of the female parent selection.

Plants of the new Nemesia differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Nemesia have larger flowers than plants of the male parent selection.
  • 2. Plants of the new Nemesia and the male parent selection differ in flower color as plants of the male parent selection have white to soft pink-colored flowers.

Plants of the new Nemesia can be compared to plants of the cultivar Intraiyel, disclosed in a U.S. Plant Patent application filed concurrently. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Nemesia differed primarily from plants of the cultivar Intraiyel in flower color as plants of the cultivar Intraiyel had pale yellow-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Nemesia, 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 colors of the new Nemesia.

The photograph at the bottom of the sheet comprises a side perspective view of a typical plant of ‘Intraired’ grown in a container.

The photograph at the top of the sheet comprises a close-up view of typical flowers of ‘Intraired’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and averaged measurements describe plants grown in Bonsall, Calif., in an outdoor nursery during the late summer with day temperatures ranging from 18° C. to 35° C. and night temperatures ranging from 16° C. to 24° C. After rooting, plants were grown for ten weeks in 15-cm containers with one plant per container. Color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
