Senecio cruentus (Masson ex L′Hér.) DC.
‘Sunsenebubakai’
The present invention relates to a new and distinct variety of Senecio plant, which is hereinafter referred to as ‘Sunsenebubakai.’
A Senecio cruentus (Masson ex L′Hér.) DC. is a very popular plant that is used in flower bedding and potting in the winter and spring seasons.
The purpose of this invention is to obtain a new Senecio cultivar with abundant and large sized petals having blue and white-bicolored ray floerts, and an upright and medium sized appearance.
The new Senecio plant originated from cross-pollination of the female parent ‘09-83’ and the male parent ‘09-09’. The female parent ‘09-83’ (unpatented) used in the crossing of ‘Sunsenebubakai’ is a strain of the applicant's breeding lines (i.e., proprietary Senecio selection), having white petals, and the male parent ‘09-09’ (unpatented) used in the crossing of ‘Sunsenebubakai’ is a strain of the applicant's breeding lines (i.e., proprietary Senecio selection), having light blue and pink-bicolored petals. The cross-pollination was conducted in March, 2010, at Higashiomi, Shiga, Japan.
In February 2011, the seedlings obtained by the crossing were planted in a field, and some seedlings were selected in view of growth habit, flower size and color thereof. Shortly thereafter stem tip culturing was carried out, and then the propagation was started.
In November 2013, the cultivation of the seedlings was repeated. The botanical characteristics of that plant were then examined, using similar variety ‘Sunsenebuba’ for comparison. As a result, it was concluded that this Senecio plant is distinguishable from any other variety, whose existence is known, and has uniform and stable characteristics.
The new variety of Senecio plant was then named ‘Sunsenebubakai’.
This new variety is unlike any Senecio commercially available as evidenced by the following unique combinations of characteristics.
1. Abundant and large sized petals having blue and white-bicolored ray floerts.
2. Upright and medium sized appearance.
The new variety ‘Sunsenebubakai’ differs from the similar variety ‘Sunsenebuba’, which was applied for Japanese plant variety protection (the application number: 12095; the application date: 199/11/10; the registration number 10653; the registration date: 2002Sep. 31), in the following points.
1. The ray floret color of ‘Sunsenebubakai’ is bicolor, blue (95B) and white (NN155C). That of ‘Sunsenebuba’ is bicolor, violet-blue (93B) and white (NN155C).
2. The flower diameter of ‘Sunsenebubakai’ is about 81 mm. That of ‘Sunsenebuba’ is about 68 mm.
3. Ray floret length of ‘Sunsenebubakai’ is about 31 mm. That of ‘Sunsenebuba’ is about 27 mm.
4. The disc diameter of ‘Sunsenebubakai’ is about 16 mm. That of ‘Sunsenebuba’ is about 12 mm.
This new variety of Senecio plant ‘Sunsenebubakai’ 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 November 2013 while growing outdoors in wall pots which were about 15 cm in size at an age of approximately 6 months.
In November 2013, the cultivation of the seedlings was repeated at Higashiomi, Shiga, Japan. The average day temperature was about 10° C., and the average night temperature was about 5° C. The plants were grown under natural sunlight. The number of days to flowering (response time) was about 22 weeks. The quality was maintained for about 150 days. The plants had temperature resistance to about 0° C. (the lowest temperature) and about 30° C. (the highest temperature). Further, the plants had the same tolerance to pests and pathogens as a typical Senecio plant.
For the parentage information: The female parent ‘09-83’ (unpatented) used in the crossing of ‘Sunsenebubakai’ is a strain of the applicant's breeding lines (i.e., proprietary selection of Senecio cruentus), having white petals, and the male parent ‘09-09’ (unpatented) used in the crossing of ‘Sunsenebubakai’ is a strain of the applicant's breeding lines (i.e., proprietary selection of Senecio cruentus), having light blue and pink-bicolored petals.
For the propagation information: the number of days in which roots started to form during the summer was about 7 days; approximate soil and/or air temperature during the summer was around 18-20° C.; number of days in which roots started to form during the winter was about 7 days; approximate soil and/or air temperature during the winter was around 18-20° C.; number of days to produce a rooted young plant during the summer was about 28 days; number of days to produce a rooted young plant during the winter was about 28 days; root density was fine; root branching was free; root color was white; and root texture was fibrous.
The botanical characteristics of the new and distinct variety of Senecio plant named ‘Sunsenebubakai’ at an age of approximately 6 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 5th edition 2007).
This new variety of Senecio plant having the above botanical characteristics is suitable for flower bedding and potting, particularly in hanging pots or planters.
This application is related to and claims priority under 35 U.S.C. 119 to U.S. provisional plant patent application 61/965,150, filed Jan. 23, 2014, entitled ‘Sunsenebubakai.’
