Abstract

A new and distinct cultivar of Canna×generalis plant named ‘Balcanyel’, characterized by its dwarf habit, flowers having bright yellow petaloid staminodia with sparsely scattered red stippling, and dark green slightly glaucous mature foliage.

Description

Latin name of the genus and species of the plant claimed: Canna×generalis.

Variety denomination: ‘Balcanyel’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Canna, botanically known as Canna×generalis, hereinafter referred to by the name ‘Balcanyel’.

The new Canna is a product of a planned breeding program conducted by the inventor in Emmet, Ark. The objective of the breeding program is to create new dwarf Canna varieties having many large blossoms of various shapes and colors; various foliage colors; and resistance to insect pests. The Canna cultivars will bloom prolifically and have self-cleaning blooms.

The new Canna originated from a cross made by the inventor in Tifton, Ga. in 2000, of the Canna×generalis, cultivar Picasso, a 1.5 to 1.8 m tall plant with green leavews and light yellow, 7.6 cm diameter blooms having densely scattered red stippling on the petaloid staminodia, as the female, or seed, parent. The male parent was Canna×generalis cultivar Liberty Yellow, a 0.9 to 1.2 m tall plant, with creamy-yellow, 7.6 cm diameter blooms having sparsely scattered orange stippling on the petaloid staminodia. Neither parent cultivar has been patented.

Compared to plants of the female parent, ‘Picasso’, the cultivar Balcanyel is dwarf being on average 60 cm tall rather than 1.5 to 1.8 m tall, has dark green slightly glaucous mature foliage rather than green foliage, has three racemes with 15-20 blooms rather than two racemes with 10-15 blooms, and has on average 11.4 cm diameter bright yellow blooms with sparsely scattered red stippling on the petaloid staminodia rather than 7.6 cm light yellow blooms with densely scattered red stippling on the petaloid staminodia. Cultivar Balcanyel sheds the old blooms from the racemes; whereas, the old blossoms of cultivar Picasso are persistent. The cultivar Picasso has severe Canna leaf-roller insect damage, but cultivar Balcanyel has only moderate leaf-roller insect damage.

Compared to plants of the male parent, ‘Liberty Yellow’, the cultivar Balcanyel is dwarf being on average 60 cm tall rather than 0.9 to 1.2 m tall, has dark green slightly glaucous mature foliage rather than green foliage, has three racemes with 15-20 blooms rather than two racemes with 10-15 blooms, has on average 11.4 cm diameter bright yellow blooms rather than 7.6 cm creamy yellow blooms, and has red stippling on the petaloid staminodia rather than orange stippling on the petaloid staminodia. The cultivar Balcanyel is more susceptible to Canna leaf-roller as exhibited by moderate damage rather than a slight level of damage for ‘Liberty Yellow’.

The cultivar Balcanyel was discovered and selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Emmet, Ark. The cultivar Balcanyel is perennial to Zone 7.

Asexual reproduction of the new Canna by rhizomes in a controlled environment in Emmet, Ark. has shown that the unique features of this new Canna are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Balcanyel’. These characteristics in combination distinguish ‘Balcanyel’ as a new and distinct cultivar:

- 1. Dwarf having an average height of 60 cm;
- 2. Stalks producing three racemes, and each raceme containing a range of 15-20 blooms that are on average 11.4 cm in diameter;
- 3. Bright yellow petaloid staminodia with sparsely scattered red stippling;
- 4. Dark green slightly glaucous mature foliage; and
- 5. Moderately susceptible to Canna leaf-roller insect damage.

A preferred comparison plant of the new Canna ‘Balcanyel’ would be the patented cultivar Roblibkey, U.S. Plant Pat. No. 11,129. ‘Roblibkey’ was reported to be marketed in the United States under the name Liberty™ Keylime; however, the plant appears to be commercially unavailable. In a comparison based on the information in U.S. Plant Pat. No. 11,129, ‘Roblibkey’ plants have pale yellow with lime-green hue petaloid staminodia while the new Canna ‘Balcanyel’ have bright yellow petaloid staminodia with sparsely scattered red stippling.

Plants of the new Canna ‘Balcanyel’ can be compared to commercially available plants of ‘The President’, not patented. In side-by-side comparisons conducted in West Chicago, Ill., plants of the new Canna ‘Balcanyel’ differ from plants of ‘The President’ in the following characteristics:

- 1. Plants of the new Canna ‘Balcanyel’ are dwarf having an average height of 60 cm compared to an average height of 97 cm for ‘The President’; and
- 2. Plants of the new Canna ‘Balcanyel’ have bright yellow petaloid staminodia with sparsely scattered red stippling compared to solid scarlet red, RHS 42C, petaloid staminodia for ‘The President’.

Plants of the new Canna ‘Balcanyel’ can be compared to commercially available plants of ‘Rose Futurity’, not patented. In side-by-side comparisons conducted in West Chicago, Ill., plants of the new Canna ‘Balcanyel’ differ from plants of ‘Rose Futurity’ in the following characteristics:

- 1. Plants of the new Canna ‘Balcanyel’ are dwarf having an average height of 60 cm compared to 73.6 cm for ‘Rose Futurity’;
- 2. Plants of the new Canna ‘Balcanyel’ have bright yellow petaloid staminodia with sparsely scattered red stippling compared to solid scarlet red, RHS solid 52B, petaloid staminodia for ‘Rose Futurity’; and
- 3. Plants of the new Canna ‘Balcanyel’ have dark green slightly glaucous mature leaves compared to dark purple, RHS N187A with midvein and leaf edge 187A and core of midvein 194A.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates 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 photograph differ from the color values cited in the detailed botanical description that accurately describe the colors of the new Canna.

The photograph comprises a side perspective view of a single flowering plant of ‘Balcanyel’ grown in a one-gallon container.

DETAILED BOTANICAL DESCRIPTION

The cultivar Balcanyel has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, light intensity, water status and/or fertilizer rate or type without, however, any variance in genotype.

The photograph and following observations, measurements and values describe plants grown in West Chicago, Ill. with one plant per one-gallon container in polyethylene-covered greenhouses during the winter-spring seasons under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from 72-89° F. and night temperatures ranged from 55-65° F. Plants were approximately two months old when the photograph and color values were determined. The chart used in the identification of the colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition. The color values were determined on Jun. 15, 2005 under natural daylight conditions.
