Dahlia plant named ‘Balnovches’

Abstract

A new and distinct Dahlia plant named ‘Balnovches’, characterized by its yellow inflorescences with red accents, upright mounded form and moderately vigorous growth habit, is provided.

Description

Latin name of genus and species of plant claimed: Dahlia pinnata.

Variety denomination: ‘Balnovches’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct Dahlia plant, botanically known as Dahlia pinnata and hereinafter referred to by the cultivar name ‘Balnovches’.

The new cultivar is the product of a planned breeding program. The female (seed) parent of ‘Balnovches’ was the Dahlia pinnata variety ‘Figaro White’ (unpatented) which exhibits white inflorescences. The male (pollen) parent of ‘Balnovches’ was a mix of pollen from the Dahlia pinnata series ‘Figaro Improved’ (unpatented), which may exhibit inflorescences of red, rose, mauve, salmon, yellow or white. The new Dahlia was discovered and selected as a single flowering plant from within the progency of the above stated cross during 1998-1999 in Elburn, Ill. and was initially designated ‘PAS11428-3’.

Asexual reproduction of the new cultivar by terminal tip cuttings taken during 2001 at West Chicago, Ill., has demonstrated that the characteristics of the new cultivar as herein described are firmly fixed and are retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

It was found that the cultivar of the present invention:

(a) exhibits upright mounded form;

(b) forms semi-double yellow inflorescences with red accents; and

(c) exhibits a moderately vigorous growth habit.

‘Balnovches’ has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length.

The new cultivar of the present invention can be compared to ‘Linda’ (U.S. Plant Pat. No. 7,779). However, in side-by-side comparisons, ‘Balnovches’ exhibits ray florets of a different color and fewer ray florets per inflorescence than ‘Linda’.

BRIEF DESCRIPTION OF PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. The plants were grown for nine (9) weeks in a greenhouse at West Chicago, Ill.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors described herein is The R.H.S Colour Chart of The Royal Horticultural Society, London, England. The color values were determined on Nov. 21, 2001 in West Chicago, Ill. The readings were taken between 10:00 and 11:45 a.m. under natural light conditions. The plants were produced from cuttings taken from stock plants and were grown in 15 cm pots in a double polycarbonate covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown while utilizing a soilless growth medium and maintaining temperatures of approximately 65° to 70° F. (18° to 21° C.) during the day and approximately 60° to 65° F. (15° to 18° C.) during the night. Light levels between 4,000 and 6,000 footcandles were maintained. Plants were nine (9) weeks after the planting of rooted cuttings.
