Rose plant named ‘Felix Leclerc’

Abstract

A new and distinct variety of rose plant, distinguished by its medium pink flowers with a light yellow center, disease resistance and new shoot colour.

Description

Latin name of the genus and species of the plant claimed: Rosa sp.

Variety denomination: ‘Félix Leclerc’.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose named ‘Félix Leclerc’. The new rose ‘Félix Leclerc’ resulted from a hybridization programme and is a selection from a cross by manual pollination between lines ‘L25’ (unpatented) and ‘D25’ (unpatented). ‘D25’ is the pollen parent which came from the ‘D07’ (unpatented) breeding line and was obtained from a second open-pollinated seedling generation, originating from a cross between ‘Suzanne’ and ‘Red Dawn’ (unpatented). ‘L25’ is the female parent, originating from a cross between Rosa kordesii and ‘D07’ and Rosa kordesii Wulff. A genealogy chart for ‘Félix Leclerc’ is shown at FIG. 1.

The cultivar was created in Ottawa in 1977, Canada, and selection subsequently occurred at another location in Québec, Canada in 1998-1999. The comparative tests and trials for ‘Félix Leclerc’ were conducted at the Ferme experimentale de l'Acadie in Québec. The plants were grown in 2 parcels, with 1 m spacing between plants.

The ‘Félix Leclerc’ rose plant variety of the present invention: a) is resistant to foliage diseases, b) has at least 2 flowering periods in which medium pink flowers with some light yellow at the center, c) the flowers have fewer petals, d) in cooler temperatures the rose is a small shrub rose but when grown in milder conditions (such as the lower Fraser Valley in British Columbia) the rose can be 4 to 5 feet and more columnar in shape, e) has dark green foliage that offers an attractive contrast to the bloom colour, and f) new shoots are more maroon in colour and contain more anthocyanin.

Asexual reproduction of this new variety shows that the foregoing and other characteristics come true to form, are firmly fixed, and are established and transmitted through succeeding propagations. This cultivar was asexually propagated in L'Acadie, Quebec via soft-wood cutting. Cutting size can be variable but new shoots (soft-wood) taken 35 nodes in length root well under intermittent mist, common in the industry. Root hormone (IBA) can speed root development.

DETAILED DESCRIPTION

The original variety and progeny have been observed growing in a cultivated area in Québec, Canada. The observed plants used in the assessment of the characteristics described below were planted in 2001 and had reached mature stature when assessed in 2005 (4 years old) and when assessed again in 2008 (7 years old). Plants were assessed during the first major cycle of flowering (June) and in early July when time permitted the vegetative assessment. Certain characteristics of this variety, such as growth and colour, may change with changing environmental conditions (e.g., light, temperature, moisture, nutrient availability, or other factors). Colour descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise. Colour designations are made with reference to The Royal Horticultural Society (R.H.S.) Colour Chart. All colour characteristics were determined using the 1986 version of The Royal Horticultural Society (R.H.S.) colour charts and measured characteristics were based on ten plan measurements. It should be understood that the colours may vary, depending on factors such as growing and lighting conditions.

The ‘Félix Leclerc’ rose was compared to the ‘Marie-Victorin’ variety (U.S. Pat. No. PP11,650), referred to as the “reference variety.” ‘Félix Leclerc’ can be readily distinguished from ‘Marie-Victorin’ by the colour of the bloom, where ‘Marie-Victorin’ has a more prominent yellow base, and by the absence of large fruit on the plant, where ‘Marie-Victorin’ does carry large fruit.

‘Felix LeClerc’ can be distinguished from the parent — D25 and L25 by the following:

• • (a) D25 (unpatented) is a tall (>2 meters ht) deep pink flowered shrub that was developed as a breeding line and is no longer in existence;
  • (b) L25 (unpatented) was developed from a cross between ‘Red Dawn’ (unpatented) and ‘Suzanne’ (unpatented) via open and controlled cross-pollination. It is medium pink-red to light red. It has long arching canes typical of many of the early Explorer roses (also known as pillar roses). It produces many pear shaped red fruit that is generally fertile. ‘Felix LeClerc’ is not very fertile, considerable shorter in stature and varies in flower color.
• Species: Rosa ‘Félix Leclerc’.
• Plant:
  • • Height.—Up to 4 to 5 feet; shorter in cooler regions.
    • Width.—Up to 1.5 m; narrower in cooler regions.
    • Habit.—In cooler temperatures the rose is a small shrub rose but when grown in milder conditions (such as the lower Fraser Valley in British Columbia) the rose can be 4 to 5 feet and more columnar in shape.
• Commercial classification: Small hardy shrub rose.
