USPP17087P3 - Petunia plant named ‘Suncopapin’ - Google Patents

Abstract

Disclosed herein is a new and distinct variety of Petunia plant having a decumbent habit and short stems. The Petunia plant has abundant branching, and a great profusion of blooms, the whole plant remaining in bloom for a considerable period of time. The flowers are single and small, the petals having vivid reddish purple color. The inside color of the corolla throat is light purplish pink and the outside of the corolla tube is pale yellow green. The plant exhibits high resistance to heat, cold and disease.

Description

Botanical designation: Petunia hybrida.

Variety denomination: ‘Suncopapin’.

BACKGROUND OF THE VARIETY

The present invention relates to a new and distinct variety of Petunia plant originated from crossing of a Petunia hybrid variety called ‘9Pt-13a’ as the female parent and ‘96PWE-5-C20’ as the male parent.

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 known to the inventors which do not have an upright growth habit and which have a high resistance to rain, heat, and disease. 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 low plant height, abundant branching, and a high resistance to heat, rain and disease. However, there are only a few Petunia varieties known to the inventors having a decumbent and compact plant shape, a great profusion of small size flowers, reddish purple petals and a high resistance to rain, heat, and disease. Accordingly, this invention was aimed at obtaining a new Petunia variety having vivid reddish purple petals, together with the above features.

Progress

The female parent ‘9Pt-13a’ (unpatented) used in the crossing of ‘Suncopapin’ is a strain of our breeding lines, having a spreading growth habit with many branches. It has medium size single flowers, the petals having vivid reddish purple color. The growth of the female parent, ‘9Pt-13a’ is spreading, while that of ‘Suncopapin’ is decumbent.

The male parent ‘96PWE-5-C20’ (unpatented) used in the crossing of ‘Suncopapin’ 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 with pale purplish pink eye. The size of the flower of the male parent ‘96PWE-5-C20’ is smaller than that of ‘Suncopapin’.

In July 2000, crossing of ‘9Pt-13a’ as the female parent and ‘96PWE-5-C20’ 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 ‘Sunmipi’ (unpatented) and ‘Revolution Pinkmini’ (U.S. Plant Pat. No. 9,556) 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. Then the new variety of Petunia plant was named ‘Suncopapin’.

In the following description, the color-coding is in accordance with The R.H.S. Colour Chart.

SUMMARY OF THE VARIETY

This new variety is unlike any Petunia commercially available, known to the inventors, 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 vivid reddish purple (R.H.S.74A).
  • 4. The plant has a high resistance to cold, heat and disease.

The new variety ‘Suncopapin’ differs from the similar variety ‘Sunmipi’ (unpatented) in the following points.

• • 1. The spreading area of ‘Suncopapin’ is smaller than that of ‘Sunmipi’.
  • 2. The stem of ‘Suncopapin’ is shorter and thinner than that of ‘Sunmipi’.
  • 3. The internode length of ‘Suncopapin’ is shorter than that of ‘Sunmipi’.
  • 4. The leaf of ‘Suncopapin’ is shorter and thinner than that of ‘Sunmipi’.
  • 5. The bottom color of corolla throat ‘Suncopapin’ is light purplish pink (R.H.S. 65B) and the outside color of corolla throat is pale yellow green (R.H.S.145D). That of ‘Sunmipi’ is purplish white (R.H.S. N155B) and strong purplish pink (R.H.S. 73B).
  • 6. The apex shape of petal of Suncopapin is obtuse. That of ‘Sunmipi’ is rounded.

The new variety ‘Suncopapin’ differs from the similar variety ‘Revolution Pinkmini’ (U.S. Plant Pat. No. 9,556) in the following points.

• • 1. The spreading area of ‘Suncopapin’ is smaller than that of ‘Revolution Pinkmini’.
  • 2. The stem of ‘Suncopapin’ is thinner than that of ‘Revolution Pinkmini’.
  • 3. The leaf of ‘Suncopapin’ is shorter and thinner than that of ‘Revolution Pinkmini’.
  • 4. The petal color of ‘Suncopapin’ is vivid reddish purple (R.H.S.74A). That of ‘Revolution Pinkmini’ is deep purplish pink (R.H.S.68A).
  • 5. The apex shape of petal of ‘Suncopapin’ is obtuse. That of ‘Revolution Pinkmini’ is rounded.

The new variety of Petunia plant ‘Suncopapin’ 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.
