Abstract

A new variety of yellow floribunda rose plant distinguished by the deep rich color of its blooms and the high glossy green color of its foliage which enhances the beauty of the flower; by the improved vase life performance of the cut flowers for holding color and shape; by its vigorous growing habit and resistance to disease; and by its free and continuous blooming habit under greenhouse culture.

Description

BACKGROUND OF THE NEW PLANT
This new variety of yellow rose plant originated as a seedling resulting from breeding efforts carried on by me at Richmond, Ind., with the object of producing rose plants having better flower production and growing habits as well as improved color and keeping qualities. The crossing to produce this plant was done in March 1970 and the first flower from the resulting seedling occurred in October 1971. The improved and favorable characteristics of the new plant led to my asexual propagation of the plant by budding at Richmond, Ind., and further propagation under my direction through successive generations at Hamilton City, Calif., has demonstrated that its distinctive features hold true from generation to generation and appear to be firmly fixed. Greenhouse propagation and growing of this new plant in preparation for introduction to the commercial market has been carried on at Richmond, Ind., since 1973.
DESCRIPTION OF THE DRAWING
My new variety of yellow rose plant is illustrated by the accompanying photographic drawing which shows, in full color, newly opened and three-day opened flowers, several stages of bud opening, young and mature leaves, and specimens of young and old wood, the colors shown being as nearly true as can be obtained by conventional photographic procedures.

Compared to its seed parent, this new plant is considered to be superior because of its deep rich color and dark glossy foliage which brings out the attractiveness of the variety. Also, it has the advantageous characteristic of a much longer vase life which is seldom found in a yellow rose.
This variety is also much better than its pollen parent, Hoosier Gold, in that it holds a better and more consistent bud shape and color. The color is a richer yellow type floribunda with better growing habits than Hoosier Gold in that it has a longer stretch in stem length and is very productive even in low light conditions.
