Abstract

A new and distinct Petunia plant named ‘Balrufrose’, characterized by its fully double, rose colored flowers, mounded-trailing habit and dark green leaves.

Description

Latin name of the genus and species of plant claimed: Petunia×hybrida.
Variety Denomination: ‘Balrufrose’.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct Double Petunia plant, botanically known as Petunia×hybrida, and hereinafter referred to by the cultivar name ‘Balrufrose’.
‘Balrufrose’ is the result of a planned breeding program with the objective of developing Petunia cultivars with large, double flowers and vigorous mounded trailing growth habits.
The female parent of ‘Balrufrose’ was the proprietary Petunia×hybrida variety, designated ‘BFP-10’ (Trialing Pink), which exhibits a vigorous trailing habit, dark green foliage and single pink flowers. The male parent of ‘Balrufrose’ was the propriety Petunia×hybrida variety, designated ‘30251-1’, which exhibits medium vigor, mounded trailing habit, dark green foliage and double coral flowers. The new cultivar was discovered and selected as a single seeding originating from within the progeny of the above stated cross during September 1998 in a controlled environment at Arroyo Grande, Calif. and initially designated ‘BFP-672’ and subsequently named ‘Balrufrose’.
Asexual reproduction of the new cultivar has been carried out at Arroyo Grande, Calif. and West Chicago, Ill. by terminal tip cuttings and has demonstrated that the unique characteristics of the new cultivar as herein described are firmly fixed and retained through successive generations of such asexual propagation.
SUMMARY OF THE INVENTION
It was found that the cultivar of the present invention:
(a) exhibits fully double, bright rose colored flowers;
(b) forms a dark green foliage;
(c) exhibits a good basal branching character; and
(d) exhibits a mounded trailing growth habit.
The new cultivar of the present invention can be compared to Petunia plant named ‘Cobink’ (U.S. Plant Pat. No. 12,012). However, in side-by-side comparisons, plants of the new cultivar are more floriferous, exhibit smaller leaves and shorter internodes than ‘Cobink’. The flowers of ‘Balrufrose’ have more petals and are darker in color than those of ‘Cobink’.
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 12 weeks in a greenhouse at West Chicago, Ill., U.S.A.
DETAILED BOTANICAL DESCRIPTION
The cultivar ‘Balrufrose’ 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 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 Oct. 15, 2001. The readings were taken between 1:00 and 3:00 p.m. under natural daylight conditions.
Plants used for the following descriptions and measurements were grown in 10 cm pots for 12 weeks from rooted cuttings. The plants were produced from cuttings taken from stock plants and grown in a double polycarbonate covered greenhouse under conditions comparable to those used in commercial practice. A soilless growth medium was utilized while temperatures of approximately 55° to 75° F. (13° to 24° C.) during the day and approximately 50° to 60° F. (10° to 16° C.) during the night and light levels of 5,000 to 8,000 footcandles were maintained.
