Abstract

Disclosed herein is a new and distinct variety of Catharanthus plant having vigorous, upright plant habit, abundant branching, especially basally branching, developed from the base of the plant throughout the growing season and great profusion of double, bright red purple flowers.

Description

Botanical designation: Catharanthus roseus.

Cultivar denomination: ‘Suncatha 2335’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of Catharanthus plant, which is hereinafter referred to by the name of ‘Suncatha 2335’.

Catharanthus roseus, which is also known as Vinca rosea, is a very popular plant that is used for flower bedding and potting in the summer and autumn season.

The purpose of this invention is to obtain a new Catharanthus cultivar having vigorous, upright plant characteristics, abundant branching, especially basally branching, developed from the base of the plant throughout the growing season and great profusion of double, bright red purple flowers, the entire bush remaining in bloom for a considerable period of time.

The new Catharanthus plant was originated from a cross-pollination of the female parent ‘S22-P-5’ and the male parent ‘Daiichi-SIR22-16’. The female parent ‘S22-P-5’ (unpatented) used in the crossing of ‘Suncatha 2335’ is a strain of applicant's breeding lines (i.e., proprietary Catharanthus roseus selection), having pale pink petals, and the male parent ‘Daiichi-SIR22-16’ used in the crossing of ‘Suncatha 2335’ is a strain of applicant's breeding lines (i.e., proprietary Catharanthus roseus selection), having red single petals, which was applied for Japanese plant variety protection (the application number: 25152; the application date: 2010 Aug. 31; the registration number: 21647; the registration date: 2012 Mar. 19). The cross-pollination was conducted in Sep. 10, 2010 at Yame-gun, Fukuoka, Japan.

In February 2012, the seedlings obtained by the crossing were planted in field, and some seedlings were selected in view of growth habit, flower size and color thereof. In August 2012, the stem tip culturing was carried out, and then the propagation was started.

In July 2013, the cultivation of the seedlings was repeated. The botanical characteristics of that plant were then examined, using similar varieties ‘Daiichi-S23-25’ and ‘Daiichi-SIR22-16’ for comparison. As a result, it was concluded that this Catharanthus plant is distinguishable from any other variety, whose existence is currently known, and is uniform and stable in its characteristics.

The new variety of Catharanthus roseus plant is named ‘Suncatha 2335’.

SUMMARY OF THE INVENTION

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

- 1. Vigorous, upright plant characteristics.
- 2. Abundant branching, especially basally branching, developed from the base of the plant throughout the growing season.
- 3. Great profusion of double, bright red purple flowers, the entire bush remaining in bloom for a considerable period of time.

The new variety ‘Suncatha 2335’ differs from the similar variety ‘Daiichi-S23-25’, which was applied for Japanese plant variety protection (the application number: 27372; the application date: Sep. 3, 2012; the registration number 23254; the registration date: Mar. 12, 2014), in the following points.

- 1. The main color of surface of corolla lobe of ‘Suncatha 2335’ is bright red purple (RHS N66C). That of ‘Daiichi-S23-25’ is PURPLE-VIOLET (RHS near N80A).

The new variety ‘Suncatha 2335’ differs from the similar variety ‘Daiichi-SIR22-16’, which was applied for Japanese plant variety protection (the application number: 25152; the application date: 2010 Aug. 31; the registration number 21647; the registration date: Mar. 19, 2012), in the following points.

- 1. The main color of surface of corolla lobe of ‘Suncatha 2335’ is bright red purple (RHS N66C). That of ‘Daiichi-SIR22-16’ is white (RHS NN155C).
- 2. The leaf size (L×W) of ‘Suncatha 2335’ is 49 mm×23 mm. That of ‘Daiichi-SIR22-16’ is 45 mm×28 mm.
- 3. The petiole length of ‘Suncatha 2335’ is 10.5 mm. That of ‘Daiichi-SIR22-16’ is 7.0 mm.

This new variety of Catharanthus plant ‘Suncatha 2335’ was asexially reproduced by the use of cuttings at Higashiomi, Shiga, Japan, and homogeneity and stability thereof were confirmed. The instant plant retains its distinctive characteristics and produces true to type in successive generations.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The depicted plants had been reproduced by the use of cuttings and were photographed during October 2013 while growing outdoors in wall pots with about 15 cm of container size at an age of approximately 6 months.

The second sheet is a photograph of a typical plant of the new variety of Catharanthus plant ‘Suncatha 2335’ while growing in a pot.

The first sheet is a photograph of a close view of flowers of the new variety of Catharanthus plant ‘Suncatha 2335’.

DETAILED BOTANICAL DESCRIPTION

In October 2013, the cultivation of the seedlings was repeated at Higashiomi, Shiga, Japan. The average day temperature was about 25° C., and the average night temperature was about 15° C. The plants were grown under natural sunlight. The number of days to flowering (response time) was about 3 to 4 weeks. The keeping quality was about 180 days. The plants had temperature resistance to about 5° C. (the lowest temperature) and about 35 to 40° C. (the highest temperature). Further, the plants had the same tolerance to pests and pathogens as a typical Catharanthus plant.

For the parentage information: The female parent ‘S22-P-5’ (unpatented) used in the crossing of ‘Suncatha 2335’ is a strain of applicant's breeding lines (i.e., proprietary Catharanthus roseus selection), having pale pink petals, and the male parent ‘Daiichi-SIR22-16’ used in the crossing of ‘Suncatha 2335’ is a strain of applicant's breeding lines (i.e., proprietary Catharanthus roseus selection), having red single petals, which was applied for Japanese plant variety protection (the application number: 25152; the application date: Aug. 31, 2010; the registration number: 21647; the registration date: Mar. 19, 2012).

For the propagation information: the new cultivar was propagated by cutting; the number of days to initiate roots during the summer was about two weeks; approximate soil and/or air temperature during the summer was around 30° C.; the number of days to initiate roots during the winter was about three weeks; approximate soil and/or air temperature during the winter was around 25° C.; the number of days to produce a rooted young plant during the summer was about five weeks; the number of days to produce a rooted young plant during the winter was about six weeks; root density was moderate; root branching was free; root color was white; and root texture was fibrous.

The botanical characteristics of the new and distinct variety of Catharanthus plant named ‘Suncatha 2335’ at an age of approximately 4 months are shown in the following Table. 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 The 5th edition 2007).
