Hybrid tea rose plant named `Ruikuik`

A new variety of hybrid tea rose plant having cream colored flowers and suitable for growing under glass.

SUMMARY OF THE INVENTION 
The present invention relates to a new and distinct variety of rose plant 
of the hybrid tea rose class which was discovered as a naturally occurring 
mutation in a controlled planting of the variety `Ruirovingt`, U.S. Plant 
Pat. No. 8,528. The varietal denomination of the new variety is `Ruikuik`. 
The new variety was isolated and asexually reproduced by budding in 
Holland. 
Among the novel characteristics possessed by this new variety which 
distinguish it from its parent and all other varieties of which I am aware 
are its attractive cream colored flowers borne on a floriferous plant with 
long stems and suitable for production of cut flowers under glass. The new 
variety can be reproduced through propagation by cuttings, grafting, 
budding and micropropagation. 
Asexual reproduction by budding of the new variety as performed in Holland 
shows that the foregoing and other distinguishing characteristics come 
true to form and are established and transmitted through succeeding 
propagations.

DESCRIPTION OF THE NEW VARIETY 
The following is a detailed description of the new variety, with color 
terminology in accordance with The Royal Horticultural Society Colour 
Chart (R.H.S.C.C.) and horticultural terminology in accordance with 
standard terminology used in UPOV-approved horticultural guidelines. The 
terminology used in color descriptions herein refers to plate numbers in 
the aforementioned color chart. 
Parentage: Mutation of `Ruirovingt`. 
Class: Hybrid Tea. 
As can be seen in the accompanying detail illustration there is shown a new 
shoot, 1; compound three, five and seven leaflet leaves, 2, 3 and 4, 
respectively; a stem 5; buds, 6 and 7; a flower, 8, about one-third open; 
and a flower, 9, more fully open. Also shown are flower stems 10, 11 and 
12, with reproductive organs displayed. The other illustration shows cut 
flower form of the new variety. 
The following further horticultural description is based on observations 
made of specimens grown under glass in Holland.
