Description

Botanical/commercial classification: Petunia hybrida/Petunia Plant.

Varietal denomination: cv. ‘Sunpimo’.

BACKGROUND OF THE VARIETY

The present invention relates to a new and distinct variety of Petunia plant that originated from the crossing a seedling called ‘5Pt-30-1’ as female parent and a wild type Petunia plant named ‘1796’ as male parent that is native to Brazil.

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 plants such as ‘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 low plant height, abundant branching, and a high resistance to heat, rain and disease. However, there are only a few Petunia varieties having a great profusion of flowers, softly colored flower petals and a high resistance to rain, heat, and diseases. Accordingly, this invention is aimed at obtaining a new Petunia variety having vivid reddish-purple petals with a light pink center together with the above features.

The ‘5Pt-30-1’ female parent is a strain selected in Japan from a seedling named ‘Baccarat Pink’ (non-patented in the United States).

In April 1998, crossing of ‘5Pt-30-1’ as female parent and ‘1796’ as pollen parent was conducted at the Omi R&D Center, Flower Division of Suntory Ltd. In January 1999, 120 seedlings were obtained from that crossing. These seedlings were grown in pots in glasshouses and were evaluated. One new variety was selected in view of its decumbent growth habit and its attractive flower color. That seedling was propagated by the use of cuttings from July 1999, and a further evaluation was carried out by flower potting and bedding in March 2000, at the Omi R&D Center, Flower Division of Suntory Ltd. The botanical characteristics of that plant were then examined, using the similar varieties ‘Revolution Pink-Mini’ and ‘Sunpapi’ (non-patented in the United States) for comparison. As a result, it was concluded that this Petunia plant is distinguishable from all other varieties, whose existence is known to us, and is uniform and stable in its characteristics. The new variety of Petunia plant of the present invention was named ‘Sunpimo’.
