Botanical/commercial classification: Petunia hybrida/Petunia Plant.
Varietal denomination: cv. ‘Sunchiffon’.
BACKGROUND OF THE VARIETYThe present invention relates to a new and distinct variety of Petunia plant that originated from crossing a seedling named ‘Fantasy Pink Morn’ (non-patented in the United States) (♀) and a wild-type Petunia plant named ‘40-1’ (♂) (non-patented in the United States and 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 the ‘Revolution Purple Pink’ variety (U.S. Plant Pat. No. 6,915), the ‘Revolution Brilliant Pink’ variety (U.S. Plant Pat. No. 6,914), the ‘Revolution Brilliant Pink-Mini’ variety (U.S. Plant Pat. No. 6,899), and ‘Revolution Blue Vein’ variety (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, purplish-pink colored flower petals and a high resistance to rain, heat, and diseases. Accordingly, this invention is aimed at obtaining a new Petunia variety having purplish-pink colored petals together with the above features.
In April 1998, crossing of ‘Fantasy Pink Morn’ as female parent and ‘40-1’ as pollen parent was conducted at the Omi R&D Center, Flower Division, of Suntory Ltd. In January 1999, 120 seedlings were obtained from this 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. This seedling was propagated by the use of cuttings beginning in July 1999, and a further evaluation trial was carried out by flower potting and bedding beginning 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 new Petunia plant is distinguishable from all other varieties, whose existence is known to us, and that this new plant is uniform and stable in its characteristics. The new variety of Petunia plant of the present invention was named ‘Sunchiffon’.
