Disclosed herein is a new and distinct variety of Petunia plant having a decumbent growth habit. The Petunia plant has abundant branching, and great profusion of blooms, the whole plant remaining in bloom for a considerable period of time. The flowers are single and medium size, the petals having vivid purplish red color with deep purplish red vein. The bottom color of the corolla throat is moderate purplish red and the outside of the corolla tube is light purplish pink. The plant exhibits high resistance to rain, heat, cold and diseases.

Botanical classification: Petunia hybrida.
Varietal denomination: ‘Sunrovein’.
The Petunia is a very popular plant that is used for flower bedding and potting in the summer season. There are only a few Petunia varieties which do not have an upright growth habit and which have a high resistance to rain, heat, and diseases. The Petunia plant varieties for which we previously filed patent applications, i.e., the ‘Revolution’ series (‘Revolution Purple Pink’ (U.S. Plant Pat. No. 6,915), ‘Revolution Brilliant pink’ (U.S. Plant Pat. No. 6,914), ‘Revolution Brilliant pink-mini’ (U.S. Plant Pat. No. 6,899), and ‘Revolution Blue vein’ (U.S. Plant Pat. No. 9,322)) are decumbent type plants having long stems, a lower plant height, abundant branching, and a high resistance to heat, rain and diseases. However, there are only a few Petunia varieties having a great profusion of flowers, vivid colored flower petals and a high resistance to rain, heat, cold and diseases. Accordingly, this invention was aimed at obtaining a new variety which had many flowers having vivid purplish red colored petals with deep purplish red vein, many branching and decumbent growth habit together with the above features.
The present new distinct cultivar of Petunia was created by heavy ion beam irradiation of the Petunia hybrid variety called ‘Revolution briliiant pink’. ‘Revolution brilliant pink’(U.S. Plant Pat. No. 6,914) is our Petunia hybrid variety and is grown in Shiga, Japan.
In November 1999, 5 Gy of ionic neon (135 MeV) were irradiated on 128 pieces of in-vitro meristems of ‘Revolution brilliant pink’ using the Ring Cyclotron at the Institute of Physical and Chemical Research in Japan. All shoots developed from irradiated meristems were planted in soil in a greenhouse. In April 2000, we selected a plant having vivid purplish red petals with a deep purplish red pattern. That plant was propagated by cutting, grown in pots and used in a trial in April 2001 in Yokaichi, Shiga, Japan. By October 2001, the botanical characteristics of that plant were examined. As a result, it was concluded that this new Petunia plant is distinguishable from any other variety, whose existence is known to us, and is uniform and stable in its characteristics. This new variety of Petunia plant was named ‘Sunrovein’.
The new variety of Petunia plant ‘Sunrovein’ was asexually reproduced by cutting at Yokaichi-shi, Shiga-ken, Japan, and the homogeneity and stability thereof were confirmed. The instant plant retains its distinctive characteristics and reproduces true to type in successive generations.
In the following description, the color-coding is in accordance with the Horticultural Colour Chart of The Royal Horticultural Society, London, England (R.H.S.).
The parent used to obtain this new variety ‘Sunrovein’ was ‘Revolution brilliant pink’ having very spreading habit and many branches. It has medium single flowers having vivid purplish red (near R.H.S. 74A) petals. The bottom color of the corolla throat is dark purple (near R.H.S. 83A) and outside color of the corolla tube is deep purplish pink (near R.H.S. 70C).
The main botanical characteristics of the ‘Revolution brilliant pink’ are as follows:
Physiological and ecological characteristics; Moderate resistance to cold and pests. Strong resistance to rain, heat and diseases.
The main botanical characteristics of similar variety ‘Sunrove’ (U.S. Plant Pat. No. 14,125) used for comparison are as follows:
Physiological and ecological characteristics; Moderate resistance to cold and pests. Strong resistance to rain, heat and diseases.
The main botanical characteristics of similar variety ‘Revolution hotpink marrose’ (U.S. Plant Pat. No. 10,904) used for comparison are as follows:
Physiological and ecological characteristics;—Moderate resistance to pests. Strong resistance to cold, rain, heat and diseases.
The new variety of the Petunia plant has a decumbent growth habit, abundant branching and great profusion blooms with the whole plant remaining in bloom for a considerable period of time. The flowers are single and medium size. The petal color is vivid purplish red with deep purplish red vein. The plant has a high resistance to rain, cold, heat and diseases.
The plants were reproduced by cutting and were photographed in September 2002 while growing outdoors in 24 cm pots at an age of approximately 6 months at Yokaichi-shi, Shiga-ken, Japan.
The botanical characteristics of the new and distinct variety of Petunia plant named ‘Sunrovein’, observed during September 2002 at Yokaichi-shi, Shiga-ken, Japan at an age of approximately 6 months, are as follows:
Physiological and ecological characteristics;—Moderate resistance to pests. Strong resistance to cold, rain, heat and diseases.
This new variety of Petunia plant is most suitable for flower bedding, potting and large planters. Pinching of old blossoms will enhance the formation of new blossoms.
