Botanical designation: Catharanthus roseus.
Cultivar denomination: ‘Suncathamiho’.
The present invention relates to a new and distinct variety of Catharanthus plant, which is hereinafter referred to by the name of ‘Suncathamiho’.
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, great profusion of single, pale pink flowers, the whole bush remaining in bloom for a considerable period of time and irregularity incised petals, shaped of hastate, incurvated.
The new Catharanthus plant was originated from a cross-pollination of the female parent ‘MC21-15’ and the male parent ‘MC21-P-2’. The female parent ‘MC21-15’ (unpatented) used in the crossing of ‘Suncathamiho’ is a strain of applicant's breeding lines (i.e., proprietary Catharanthus roseus selection), having white petals, and the male parent ‘MC21-P-2’ (unpatented) used in the crossing of ‘Suncathamiho’ is a strain of applicant's breeding lines (i.e., proprietary Catharanthus roseus selection), having rotund petal shape. The cross-pollination was conducted in August, 2011 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 ‘Milk crown blushing pink’ and ‘Daiichi-MC21-25’ 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 ‘Suncathamiho’.
This new variety is unlike any Catharanthus plants commercially available as evidenced by the following unique combinations of characteristics.
The new variety ‘Suncathamiho’ differs from the similar variety ‘Milk crown blushing pink’, which was applied for Japanese plant variety protection (the application number: 23662; the application date: 2009 Apr. 2; the registration number 21019; the registration date: 2011 Sep. 8), in the following points.
The new variety ‘Suncathamiho’ differs from the similar variety ‘Daiichi-MC21-25’, which was applied for Japanese plant variety protection (the application number: 26287; the application date: 2011 Sep. 8; the registration number 22599; the registration date: 2013 Jul. 29), in the following points.
This new variety of Catharanthus plant ‘Suncathamiho’ 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.
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 ‘Suncathamiho’ while growing in a pot.
The first sheet is a photograph of a close view of flowers of the new variety of Catharanthus plant ‘Suncathamiho’.
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 ‘MC21-15’ (unpatented) used in the crossing of ‘Suncathamiho’ is a strain of applicant's breeding lines (i.e., proprietary Catharanthus roseus selection), having white petals, and the male parent ‘MC21-P-2’ (unpatented) used in the crossing of ‘Suncathamiho’ is a strain of applicant's breeding lines (i.e., proprietary Catharanthus roseus selection), having rotund petal shape.
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 ‘Suncathamiho’ 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).
This new variety of Catharanthus plant having the above botanical characteristics is suitable for flower bedding and potting, particularly in hanging pots or planters.
