Abstract

Disclosed herein is a new and distinct variety of Petunia plant having a semi-decumbent growth habit. The Petunia plant has abundant branching, particularly with respect to secondary branching, and forms a great profusion of blooms with the entire plant remaining in bloom for a considerable period of time. The flowers are single and very small. The petal coloration is deep red. The base color of the corolla throat is vivid greenish-yellow and the outside of the corolla tube is olive-gray. The plant exhibits high resistance to rain, heat, drought and diseases, such as Powdery Mildew.

Description

Botanical/commercial classification: Petunia hybrida/Petunia Plant.

Varietal denomination: cv. ‘Sunbelre’.

BACKGROUND OF THE VARIETY

The Petunia is a very popular plant that is used for flower bedding and potting in the summer season. There are only a few small-flowered Petunia varieties, such as ‘Suntory SP-R’ (U.S. Plant Pat. No. 9,557), ‘Sunberubu’ (U.S. Plant Pat. No. 9,754), ‘Sunbelchipi’ (U.S. Plant Pat. No. 10,355), and ‘Sunbeluki’ (U.S. Plant Pat. No. 11,558) that are of the semi-decumbent type, possess a medium plant height with abundant branching, and possess a high resistance to heat and rain and disease. Accordingly, this invention was aimed at obtaining a new Petunia variety having deep red petals, and very small flowers combined with the above features.

The new variety of Petunia plant according to this invention originated by crossing the ‘Sunbelchipi’ variety as female parent (U.S. Plant Pat. No. 10,355) and a Petunia variety named ‘R5’ as male parent.

The crossing was conducted during May 1997 at the Omi R & D Center of SUNTORY Ltd., located at 863-1, Aza-Iketani, Omori-cho, Youkaichi-shi, Shiga-ken, Japan. From this crossing 50 seedlings were obtained and 5 seedlings were selected in view of their semi-erect growth habit and petal coloration by the end of September 1998. These 5 seedlings were grown and were evaluated during potting and bedding trials. One plant of the present invention was selected during September 1999. The selected plant was propagated by the use of cuttings and was grown in a trial in pots in greenhouses and in the field at the Omi R & D Center from April to November 2000. The botanical characteristics of the selected plant were examined, using the similar ‘Sunbelchipi’ variety (U.S. Plant Pat. No. 10,355) for comparison. As a result, it was concluded that this new Petunia plant is distinguishable from any other variety, whose existence is known to me, and is uniform and stable in its characteristics. The new Petunia variety of the present invention has been named ‘Sunbelre’.

The new variety of the present invention can be readily distinguished from the ‘Sunbelrikupi’ variety (U.S. Plant patent application Ser. No. 10/327,017, filed Dec. 24, 2002) and the ‘Sunbelkos’ variety (U.S. Plant patent application Ser. No. 10/326,967, filed Dec. 24, 2002) through an observation of the flower coloration. Each of these varieties had the same female parent. The new ‘Sunbelre’ variety of the present invention forms deep red flowers, the ‘Sunbelrikupi’ variety forms vivid reddish-purple flowers, and the ‘Sunbelkos’ variety forms deep purplish-pink flowers with a dark red center.

In the following description, the color information is in accordance with The R.H.S. Colour Chart of The Royal Horticultural Society, London, England. A color chart based on The Japan Color Standard for Horticultural Plants (J.H.S. Color Chart) is also added for reference.

SUMMARY OF THE VARIETY

This new variety of Petunia plant ‘Sunbelre’ has a semi-decumbent growth habit with abundant branching, and forms single and very small deep red flowers in a great profusion with the entire plant remaining in bloom for a considerable period of time. The plant has high tolerances to cold and heat, high resistance to pests and diseases, particularly Powdery Mildew, and high resistance to rain.

The plants described and depicted herein were propagated by the use of cuttings and were approximately ten months of age. Such cuttings were placed in a greenhouse in January, were transplanted in February, were further transplanted to pots in April and were thereafter placed outdoors, and were trimmed during August. When present in a greenhouse, the plants were grown under controlled greenhouse conditions under full sunshine with no shielding from light. The minimum greenhouse temperature was maintained above 13° C.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The depicted plants had been reproduced by the use of cuttings and were photographed during October while growing outdoors in pots at an age of approximately ten months at Youkaichi-shi, Shiga-ken, Japan.

FIG. 1 illustrates the overall growth habit of the new variety of Petunia plant ‘Sunbelre’ while flowering.

FIG. 2 illustrates a close view of the flowers and foliage of the new variety of Petunia plant ‘Sunbelre’.
