Description

Botanical/commerical classification: Petunia hybrida/Petunia Plant.

Varietal denomination: cv. ‘Suncopaho’.

BACKGROUND OF THE VARIETY

The present invention relates to a new and distinct variety of Petunia plant, which originated from the crossing of a Petunia hybrid variety called ‘9Pt-27a’ as the female parent and ‘P59d-C10’ as the male parent.

The Petunia is a very popular plant used for flower bedding and potting in the summer season. There are only a few Petunia varieties that do not have an upright growth habit and that have a high resistance to rain, heat, and diseases. Petunias of the ‘Revolution’ series include ‘Revolution Purple pink’ (U.S. Plant Pat. No. 6,915), ‘Revolution Brilliant pink’ (U.S. Plant Pat. No. 6,914), ‘Revolution Brilliantpink-Mini’ (U.S. Plant Pat. No. 6,899), and ‘Revolution Blue vein’ (U.S. Plant Pat. No. 9,322). These are decumbent type plants having long stems, a lower plant height, abundant branching, and a high resistance to heat, rain and disease. However, there are only a few Petunia varieties having a decumbent and compact plant shape, a great profusion of small size flowers, white petals and a high resistance to rain, heat, and disease. Accordingly, this invention was aimed at obtaining a new Petunia variety having white petals, together with the above features.

The female parent ‘9Pt-27a’ (unpatented) used in the crossing of ‘Suncopaho’ is a strain of our breeding lines, having a spreading growth habit with many branches. It has medium size single flowers, the petals having a yellowish white color.

The male parent ‘P59d-C10’ (unpatented) used in the crossing of ‘Suncopaho’ is a strain of our breeding lines, having a decumbent growth habit with many branches. It has small single flowers, the petals having a yellowish white color.

In July 2000, crossing of ‘9Pt-27a’ as the female parent and ‘P59d-C10’ as the pollen parent was conducted at Yokaichi-shi, Shiga-ken, Japan. In April 2001, 80 seedlings were obtained from that crossing. These seedlings were grown in pots in glasshouses and were evaluated. One seedling was selected in view of its growth habit, flower size and color in September 2001. That seedling was propagated by cutting and a trial was carried out by flower potting and bedding from April to September 2002 at Yokaichi-shi, Shiga-ken, Japan. The botanical characteristics of that plant were then examined, using similar varieties ‘Revolution White’ (U.S. Plant Pat. No. 8,768) and ‘Sunchiffon’ (U.S. Plant Pat. No. 15,024) for comparison. As a result, it was concluded that this Petunia plant is distinguishable from any other variety, whose existence is known to us, and is uniform and stable in its characteristics. The new variety of Petunia plant was named ‘Suncopaho’.

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. Colour Chart).

SUMMARY OF THE VARIETY

This new variety is unlike any Petunia commercially available as evidenced by the following unique combinations of characteristics.

• • 1. Rather compact and decumbent growth habit with short stems.
  • 2. Having abundant branching and a great profusion of blooms.
  • 3. The flowers are single and small. The petal color is yellowish white (near R.H.S.158D).
  • 4. The plant has a high resistance to cold, heat and disease.

The new variety ‘Suncopaho’ differs from the similar variety ‘Revolution White’ in the following points.

• • 1. The spreading area of ‘Suncopaho’ is smaller than that of ‘Revolution White’.
  • 2. The stem of ‘Suncopaho’ is shorter and thinner than that of ‘Revolution White’.
  • 3. The internode length of ‘Suncopaho’ is shorter than that of ‘Revolution White’.
  • 4.The leaf of ‘Suncopaho’ is smaller and thinner than that of ‘Revolution White’.
  • 5.The flower size of ‘Suncopaho’ is smaller than that of ‘Revolution White’.
  • 6.The shape of petal of ‘Suncopaho’ is very broadly obovate, while that of ‘Revolution white’ is acute.

The new variety ‘Suncopaho’ differs from the similar variety ‘Sunchiffon’ in the following points.

• • 1. The spreading area of ‘Suncopaho’ is smaller than that of ‘Sunchiffon’.
  • 2. The stem of ‘Suncopaho’ is shorter than that of ‘Sunchiffon’.
  • 3. The leaf of ‘Suncopaho’ is smaller and thinner than that of ‘Sunchiffon’.
  • 4. The petal color of ‘Suncopaho’ is yellowish white (near R.H.S.158D), while that of ‘Sunchiffon’ is moderate purplish pink (near R.H.S.68C).
  • 5. The apex shape of petal of ‘Suncopaho’ is rounded, while that of ‘Sunchiffon’ is obtuse.
  • 6. The petal lobation of ‘Suncopaho’ is deeper than that of ‘Sunchiffon’.

The new variety of Petunia plant ‘Suncopaho’ was asexually reproduced by the use of cuttings 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.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The depicted plants had been reproduced by the use of cuttings and were photographed during July 2003 while cultivating under the trial field in 15 cm pots at an age of approximately 6 months at Yokaichi-shi, Shiga-ken, Japan.

FIG. 1 is a photograph of a typical plant of the new variety of Petunia plant ‘Suncopaho’ while growing in a pot.
