ABSTRACT:
BOTANICAL/COMMERCIAL CLASSIFICATION
Rosa hygrida
/Hybrid Tea Rose Plant.
VARIETAL DENOMINATION
‘Keihatakaho’.
SUMMARY OF THE INVENTION
The new variety of
Rosa hybrida
Hybrid Tea rose plant of the present invention was discovered during 1998 in Japan while growing among plants of the ‘Febesa’ variety (U.S. Plant Pat. No. 11,529). The new variety of the present invention accordingly is believed to be a naturally-occurring mutation of the ‘Febesa’ variety of unknown causation.
The new variety was selected and preserved primarily because of its distinctive blossom coloration that differed from the parent ‘Febesa’ variety. More specifically, the ‘Febesa’ variety exhibits blossoms that are light pink in coloration whereas the new variety of the present invention forms blossoms that are a deeper pink in coloration. In addition, the number of petals per blossom is different. More specifically, the ‘Febesa’ variety commonly forms approximately 20 to 24 petals per blossom on average whereas the new variety of the present invention commonly exhibits approximately 50 petals per blossom on average.
It was found that the new variety of Hybrid Tea rose plant of the present invention possesses the following combination of characteristics:
(a) forms attractive large buds on straight erect stems,
(b) forms in abundance deep pink blossoms,
(c) forms attractive dark green semi-glossy foliage, and
(d) is particularly well suited for the production of cut flowers under greenhouse growing conditions.
The new variety well meets the needs of the horticultural industry and can be used to advantage during the commercial production of cut flowers under greenhouse growing conditions.
The new variety of the present invention also can be distinguished from the ‘Keihayanasa’ variety (U.S. Plant patent application Ser. No. 09/832,834 filed concurrently herewith) that also is a mutation of the ‘Febesa’ variety. More specifically, the ‘Keihayanasa’ variety forms salmon pink blossoms having approximately 30 to 34 petals per blossom.
The new variety of the present invention has been found to undergo asexual propagation by a number of routes, including budding, grafting, and the rooting of cuttings. Such asexual propagation by the above-mentioned methods as performed in France has shown that the characteristics of the new variety are strictly transmissible by such asexual propagation from one generation to another.
The new variety has been named the ‘Keihatakaho’ variety.
