Description

Botanical designation: Calibrachoa sp.

Variety denomination: ‘Sunbelpapi’.

BACKGROUND OF THE VARIETY

The present invention relates to a new and distinct variety of Calibrachoa plant originated from crossing a Calibrachoa hybrid variety called ‘9PP11’, as the female parent, and ‘9CPP8’, as the male parent.

The Calibrachoa is a popular plant that is used for flower bedding and potting in the summer season. There are only a few Calibrachoa varieties known to the inventor, such as ‘Sunberubu’ (U.S. Plant Pat. No. 9,754), ‘Sunbelchipi’ (U.S. Plant Pat. No. 10,355) and ‘Sunbelki’ (U.S. Plant Pat. No. 11,558), which are spreading, and have a medium plant height, with abundant branches and a high resistance to heat, rain and disease. There are even fewer varieties that have a great profusion of flowers, a strong purplish pink color, and high resistance to rain, heat, and disease known to the inventors. Accordingly, the invention was aimed at obtaining a new Calibrachoa variety having strong purplish pink and very small flowers, combined with the above features.

The female parent ‘9PP11’ (unpatented) used in the crossing of ‘Sunbelpapi’ is a strain of our breeding lines grown at Yokaichi-shi, Shiga-ken, Japan, having an outwardly spreading growth habit with abundant branching. It has small single flowers, the petals having a vivid reddish purple color. The flowers of ‘9PP11’ are smaller in size than the flowers of ‘Sunbelpapi’.

The male parent ‘9CPP8’ (unpatented) used in the crossing of ‘Sunbelpapi’ is a strain of our breeding lines grown at Yokaichi-shi, Shiga-ken, Japan, having a decumbent growth habit with abundant branching. It has small single flowers, the petals having a vivid reddish purple color. The growth habit of the male parent, ‘9CPP8’, is decumbent. In contrast, the growth habit of ‘Sunbelpapi’ is outwardly spreading.

In April 1998, crossing of ‘9PP11’ as the female parent and ‘9CPP8’ as the male parent was conducted at Yokaichi-shi, Shiga-ken, Japan. In September 1998, 50 seedlings were obtained from that crossing. One seedling was selected in view of its growth habit, flower size and color in October 1999. That seedling was propagated by cutting, and the cuttings were grown in field and evaluated from April to September 2000. A trial was carried out by flower potting in the greenhouse and field from April to October 2001 at Yokaichi-shi, Shiga-ken, Japan. The botanical characteristics of that plant were then examined, using similar varieties ‘Sunbelchipi’ (unpatented) and ‘Sunbelkupapi’ (unpatented) for comparison. As a result, it was concluded that this Calibrachoa 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 Calibrachoa plant was named ‘Sunbelpapi’.

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 Calibrachoa commercially available, known to the inventors as evidenced by the following unique combinations of characteristics.

• • 1. Compact and outwardly spreading growth habit with abundant branching.
  • 2. Having a great profusion of blooms with the entire plant remaining in bloom for a considerable period of time.
  • 3. The flowers are single and small. The petal color is strong purplish pink (R.H.S. 75A).
  • 4. The plant has a high resistance to rain, cold, heat and disease.

The new variety ‘Sunbelpapi’ differs from the similar variety ‘Sunbelchipi’ in the following points.

• • 1. The plant of ‘Sunbelpapi’ is more compact than that of ‘Sunbelchipi’.
  • 2. The leaf of ‘Sunbelpapi’ is smaller than that of ‘Sunbelchipi’.
  • 3. The leaf shape of ‘Sunbelpapi’ is elliptic. That of ‘Sunbelchipi’ is lanceolate.
  • 4. The petal color of ‘Sunbelpapi’ is strong purplish pink (R.H.S. 75A). That of ‘Sunbelchipi’ is vivid purplish red (R.H.S. N57A).
  • 5. The outside color of the corolla throat of ‘Sunbelpapi’ is light greenish yellow (R.H.S. 7D) with purplish pink (R.H.S. N74C) vein. That of ‘Sunbelchipi’ is brilliant greenish yellow (R.H.S. 5C).
  • 6. The apex shape of the petal of ‘Sunbelpapi’ is rounded. That of ‘Sunbelchipi’ is obtuse.
  • 7. The peduncle length of ‘Sunbelpapi’ is longer than that of ‘Sunbelchipi’.

The new variety ‘Sunbelpapi’ differs from the similar variety ‘Sunbelkupapi’ in the following points.

• • 1. The growth habit of ‘Sunbelpapi’ is outwardly spreading. That of ‘Sunbelkupapi’ is decumbent.
  • 2. The plant height of ‘Sunbelpapi’ is higher than that of ‘Sunbelkupapi’.
  • 3. The leaf of ‘Sunbelpapi’ is smaller than that of ‘Sunbelkupapi’.
  • 4. The leaf shape of‘Sunbelpapi’ is elliptic. That of ‘Sunbelkupapi’ is lanceolate.
  • 5. The petal color of ‘Sunbelpapi’ is strong purplish pink (R.H.S. 75A). That of ‘Sunbelkupapi’ is deep purplish pink (R.H.S. 73A) with a yellowish white (R.H.S. 115C) eye color.
  • 6. The peduncle length of ‘Sunbelpapi’ is longer than that of ‘Sunbelkupapi’.

This new variety of Calibrachoa Plant, ‘Sunbelpapi’, was asexually reproduced by the use of cuttings at Omori-cho, Yokaichi-shi, Shiga-ken, Japan, and 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 September 2001 while growing in typical outdoor conditions in 24 cm pots, and at an age of approximately 8 months, at Yokaichi-shi, Shiga-ken, Japan. The average day temperature was approximately 23° C. and the average night temperature was approximately 15° C.
