Lammerts, Freedom, Calif., assignor to Germaims, Inc., Los Angeles, Calif. Filed May 11, 1970, Ser. No. 36,504 lut. Cl. A01h 5/00 U.S. Cl. Plt.-20 1 Claim ABSTRACT OF THE DISCLOSURE A hothouse variety of hybrid tea rose originating as a seeding of Baccara (RP. 1,367) Rumba l(P.P'. 1,9119') and distinguished by an improved and more uniform red coloring of its flowers when compared with the seed parent Baccara, particularly at the 1% to 1/2 opened stage, and by a much more abundant production of flowers, which bloom from early to late season in the garden and the year around under glass.

BACKGROUND OF THB INVlENTION This new variety of rose plant has resulted from breeding eforts carried on by me at Livermore, Calif., since 1953 with the object of developing a rose which would combine the texture, keeping quality and general color range of Baccara (P.P. 1,367) with increased flower production and mproved foliage appearance. The most satisfactory results were obtained by crossing Baccara with the unrelated, very productive, floribunda variety Rumba (RP. 1,919) and the seedling originator 'of this new variety, discovered in 1965, was selected for testing and asexual propagation because the new plant appeared to combine the desired characteristics of Baccara with the glossy foliage of Rumba. Testing also showed the selected seedling to have the advantageous productivity characteristics of Rumba, and because the distinguishing and sought for features of the breeding efi'orts remained true from generation to generation of asexual reproduction, this new variety was chosen for commercial production.

Asexual propagation of this new variety was first done at Lvermore, Calif., by budding and propagation by the same method as now being done under glass at Livermore, Calif., and in the nursery at Hamilton City, Calif.

DESCRIPTLON OF THE DRA'WINGS My new variety of rose plant is illustrated by the accompanying photographic representation in which the upper view shows various stages of bloom development from new bud to the fully opened flower; and the lower view shows the front and back sides of a typical leaf, portions of the mature Wood, and a young branch showing the new Wood and foliage.

My new variety of rose plant 'most resembles` Baccara (P.P.` 1,367), itsiseed parent. There are many distinctive diiferences, however, and the most outstanding and noticeable difference is that the color of the outside petals of the fiower of the new variety, up to the time the blooms are 1A to 1/2 open, is Red 53B whereas the outside petals of B'accara at the same stage are Greyed- Purple 187A to 187B. This diiference gives the new variety a clear clean appearance at this stage, whereas, at the same stage. Baccara has a blotched appearance.

My new variety has another important advantage in that its productivity is more than double that of Baccara. My new variety produced 28 fiowers over a twelve month period, whereas Baccara produced 13 flowers during the same time. Both varieties were grown under similar conditions for this test and both were budded plants on Manetti understock.

Other noticeable difierences of my new variety of rose plant over the parent 'variety Baccara are found in the peduncle which in Baccara is of Green 143C in color andhas about 10 per inch of very small, almost hair size, prickles. The peduncle of the new variety is Yellow- Green 146D in color and has many prickles averaging 19 per inch, of a size clearly visible and some of which are like small 1/8" long thorns.

The thorns of the newV variety are larger on flolwering wood and much more red at the base than those of Baccara, which have relativelylittle red at base. The thorns of Baccara are also more slender and average 14s" less in height than thosel` of the new variety. Also, the leaves of the new variety are glossier, more serrated, less round and more pointed than those of Baccara; carry more anthocyanin on the under side than the leaves of' Baccara; and have leaf veins that are more deeply indented than Baccara.

All of the observations upon which the foregoing specification is based. were made under greenhouse conditions Vat Livermore, Calif., and Salina, Calif., and under nursery field conditions at Hamilton City, Calif.

I claim:

1. A new and distinct 'variety of rose plant substantially as herein shown and described,` characterized by the clear,.clean appearanceJ of the outer surface of the outer petals of the 1A: to 1/2 opened fiower, as compared with the seed parent Baccara at the same stage; by its doubling of the flower output of Baccara; and by its'more vigorous growth. habit and more glossy and attractive foliage than either of its parents.
