Petunia plant named ‘Sunbel-Apu’
A new and distinct variety of Petunia plant having a semi-erect habit is provided. The new Petunia plant has abundant branching particularly with respect to the secondary branching and a great profusion of blooms with the entire plant remaining in bloom for a considerable period of time. The flowers are very small with light yellowish pink petals that are formed in profusion in a spike. The blooming period commonly is from May to September. The plant exhibits high resistance to cold, rain, heat drought, and diseases, such as Powdery Mildew.

Botanical/commercial classification: Petunia hybrida/Petunia Plant.
Varietal denomination: cv. ‘Sunbel-Apu’.
BACKGROUND OF THE VARIETYThe Petunia is a very popular plant and is used for flower bedding and potting in the summer season. There are only a few varieties of the Petunia plants that do not have an upright growth habit and which have a high resistance to rain, heat, cold and diseases. Recently, there were developed a series of small-flowered Petunia varieties, such as ‘Suntory SP-R’ (U.S. Plant Pat. No. 9,557), ‘Sunberubu’ (U.S. Plant Pat. No. 9,754), ‘Sunbelochipi’ (U.S. Plant Pat. No. 10,355), and ‘Sunbelki’ (U.S. Plant Pat. No. 11,558), having a semi-erect growth habit, short stems, a medium plant height, abundant branching, and a high resistance to heat, cold and rain. However, there are only a few Petunia varieties having a great profusion of flowers, a light yellowish pink with vivid reddish orange flower color, a very small flower size, and a high resistance to rain, heat, cold and diseases. Accordingly, this invention was aimed at obtaining a new variety having a light yellowish pink with vivid reddish orange flower color, and very small flowers combined with the above features.
The new variety of Petunia plant according to this invention originated from crossing of a Petunia plant variety named ‘E2’ (non-patented in the United States) and a Petunia plant variety named ‘PE7’ (non-patented in the United States).
Initially, 10 seedlings were selected in 1994 in view of yellowish pink petal coloration and were grown at Kitakoma-gun, Yamanashi-ken, Japan. From 1995 to 1996, open-pollination with those 10 seedlings was conducted at Youkaichi-shi, Shiga-ken, Japan. From that crossing, additional seedlings were obtained. In 1997 some seedlings were selected in view of the small flower size, light yellowish pink petals with vivid reddish orange coloration and semi-erect habit. These selected seedlings were grown in beds and pots on trial basis at Kitakoma-gun, Yamanashi-ken, Japan. In September 1998 one Petunia plant of the present inventions was selected. In 1999 the botanical characteristics were examined, using similar ‘Sunbelki’ variety and the ‘Pearl Sky Blue’ variety (non-patented in the United States) for comparison. As a result, it was concluded that this Petunia is distinguishable from any other variety, whose existence is known to me and is uniform and stable in its characteristics. This new variety of Petunia plant was named ‘Sunbel-Apu’.

This new ‘Sunbel-Apu’ variety was asexually reproduced by the use of cuttings at Youkaichi-shi, Shiga-ken, Japan, and the homogeneity and stability thereof were confirmed. The characteristics of the new variety are reliably transmitted to subsequent generations by such asexual reproduction.
SUMMARY OF THE VARIETYThis new ‘Sunbel-Apu’ variety has a semi-erect growth habit with very small flowers having light yellowish pink color petals with a vivid reddish orange center. Thus, the new variety is very different from the similar ‘Sunbelki’ and the ‘Pearl Sky Blue’ varieties. The plant has a semi-erect growth habit, a compact plant shape, and abundant branching. The secondary branching is especially strong. The plant has a great profusion of blooms with the entire plant remaining in bloom for a considerable period of time. The blooming period commonly is late May to September. The flowers commonly remain open in the rainy season and the flowering duration is long. A whole plant remains in bloom for a considerable period of time.
